bialetti safety valve leaking manufacturer

The safety valve is an important safety feature of your Bialetti pot.  If steam or pressure is being regularly released from the safety valve, do not ignore as your pot may be blocked, or have a faulty safety valve.

To check for a blockage, disassemble your pot by removing the ring and filter, and cleaning inside the column of the upper chamber. Then check the funnel to ensure it is not bent nor restricting the flow of water. Finally, located in the middle of the safety valve is a small piston, move the small piston in a circular motion to remove any clogging within the valve potentially caused by lime scale or other sediment.

Should after these actions the safety valve continues to activate, cease using your pot immediately and return to your authorised Bialetti stockistfor checking/servicing.

The size of your Bialetti stovetop depends on how much coffee you like to drink in any one sitting, how strong you like it and how many people join you. When Bialetti says "2 cup", that is to say your stovetop will produce "two espresso cups" of coffee. An espresso cup of coffee generally amounts to approximately 30mls.

You must not underfill the water in the base or put too little coffee in the filter to try and achieve a lesser quantity of coffee output because this will affect the pressure and effectiveness of your stovetop. Therefore, when you purchase your Bialetti make sure you are buying the correct size for your typical use. In many Italian household"s, there are a couple of sizes in the cupboard to accommodate everyday use, versus when guests are around.

Often in New Zealand, people like to drink their coffee with milk and often quite strong (like a classic Flat White). If you were to make a Flat White with a Bialetti stovetop, it would take approximately "2 cups" of coffee, and added milk from a Tuttocrema.

If water is leaking from your safety valve, either before or during a brewing cycle, something is not quite right and it will need to be resolved before your machine is able to produce coffee again. The leak from the safety valve could be coming from one of three places:

If the leak is coming from the gold coloured safety ring, you simply need to replace it. Further details on how to do that, as well as how to prevent it happening again, can be found here. You will have received a spare safety ring with your machine.

If water is leaking from the head of the safety valve, it’s likely that the internal seal has become dislodged and damaged. Though this is a rare event, in this case the safety valve will need to be replaced. You can purchase a replacement safety valve here, and there are instructions showing how to replace the safety valve here.

A leak from this point suggests one of two things. The first is that the safety valve isn’t screwed on tight enough. Screw it in hand tight, then use a 13mm spanner to tighten it so that there is ‘metal on metal’ contact between the boiler and the safety ring. You won’t need to tighten it very hard, the thing to feel for is a sudden increase in resistance when screwing it in.

The second thing to check is whether the two red o-rings on either side of the safety ring are in good condition. Simply check that they’re well-seated either side of the safety ring and that they are clean and free of damage. Then screw the valve back onto the boiler. These o-rings form the seal between the safety valve and the boiler, so if they’re not in place the safety valve will leak. If you need some replacement seals, you can buy those here.

The devil is in the details. It is often the smallest things, the particularities, that make all the difference. This is also the case in regards to the preparation of a good coffee, a ritual in which all the steps and every single component play a fundamental role. Among all, one of the most important elements is the Moka valve. Often ignored, it is vital not only for the quality of the coffee, but also for the safety of those who prepare it.

The valve was born with the invention of the Moka Express in 1933. It is a safety valve positioned on the bottom chamber. To better understand the importance of the valve and its use, we need to take a step back and illustrate step by step

This is where the valve of the Moka comes into play. It must open when the pressure is too high. By doing so, it allows the steam to escape regularly, without causing any damage. In short, the Moka’s safety valve provides security. Hence, it should only intervene when the coffee maker is used under abnormal operating conditions.

A long-standing and debated question: how far can you fill the bottom chamber for a state-of-the-art coffee? The Moka valve can come in handy to answer this dilemma. Another important role of the valve is that it acts as a "measuring cup". Its position on the bottom chamber is not accidental. Rather, it indicates to those who prepare the coffee the correct amount of water to use. The only exception is for some special coffee pots that are already equipped with a measuring cup. Ideally the water should reach just below the safety valve.

The Moka valve, therefore, is not a decoration or a mere design element. Rather, it is a very important component for the correct functioning of the coffee maker. It guarantees safety and plays a part in the making of an excellent coffee.

Consequently, it is necessary to keep it clean and maintain it regularly. For example, using tap water to make coffee brings with it the risk of limescale deposits obstructing the hole in the valve. The resulting danger is that it could get clogged.

We have seen that one can simply use hot water to clean the Moka valve. To avoid limescale obstructions, simply move the piston that comes out of the valve along its axis when washing it. To ensure the Moka functions correctly, it is recommended to repeat this checkup periodically.

Been using my Vigano stovetop coffee pot on an electric stove for about 6 years. When I first got it I meticulously filled it to just below the safety valve yet was still scared to death of the thing blowing up if I left it too long on the hot ring. Immediately it began to glub and blub Id take it from the hot ring and stand back until it became quiescent.

That was then! I gradually discovered that as long as one does not too strenuously tamp the coffee in the basket (an unnecessary step in any case), filling the base to above the valve and leaving the pot on a low, low setting after it has "perked", is perfectly safe and gives me several cups of HOT coffee instead of one hot and the rest increasingly cooler.

Maybe your moka pot is hissing and spitting steam or your coffee is too weak. Here are the ways to fix the most common problems with a Bialetti to make sure your morning brew is everything you expect.

Three possible reasons: Either the safety valve is clogged, you’ve filled the reservoir above the fill line, or the filter may be clogged up so that the water isn’t escaping into the jug part of the pot as it should.

What to do: Take the whole pot apart, including the gasket and filter, and rinse thoroughly, wiping off any stray or stuck coffee grounds with a sponge. Also, check to see if your safety valve has a tiny protuberance (like a little metal stick that you can push from the inside)—some of my older pots had this, but my newer one doesn’t. If so, push this in a few times (it springs back again) to dislodge the blockage. If the problem continues, you might have to send the pot back or buy a new one, depending on whether it’s still under warranty.

It"s not hard to make a great cup of coffee with these machines, but there are specific things you must do, including seasoning it, loading it properly, and keeping it clean. Read How to Make Perfect Stovetop Espresso Coffee With a Bialetti Moka Pot to learn more.

If your moka pot leaks around the joint between the top and bottom, meaning the ring-shaped gasket is leaking, then check three things: 1) Is the gasket clean of coffee grounds?; 2) Is the gasket "rubbery", meaning supple and has not hardened from age and heat? (Since your moka pot is new, I"d expect the gasket to be in good shape); 3) Finally - a trick to better seal the two sections of the pot - wet the ring-shaped gasket before assembly. A few drops of water on the gasket before screwing the top and bottom sections together reduces friction of metal on rubber and allows you to easily screw the two sections together tighter.

Obviously, if the safety valve is leaking steam, then pressure is in the bottom of the pot is too high and you need to go to a coarser coffee grind and/or less coffee dose in the filter basket. Make sure you have not tamped or settled the coffee in the basket in any way.

Operating a Moka Pot seems simple: you add ground coffee and water, pop it on the stove and enjoy nice strong coffee a few minutes later. But then, one day, you witness a bubbling, dripping mess on your stovetop. If you notice a Moka Pot leaking, it’s one of the most obvious signs that your coffee maker requires some attention.

Moka Pot leaking from the middle can mean that the two chambers are not screwed together tightly enough. It is especially likely if you are new to brewing with a Moka Pot.

The pressure valve is a hole in the bottom part of the Moka Pot that prevents pressure from getting too high when you boil water in there. If you fill the lower part above the pressure valve, you will likely experience a Moka Pot valve leak. It happens because the excess water will drain out from the pressure valve.

Another potential cause of a leaking Moka Pot is a clogged pressure valve. It is a bit more serious, but it is often fixable by thoroughly cleaning once you know the issue.

Diagnosing a leaking Moka Pot can require asking questions about every step of the brewing process. This includes issues you might not remember when you think of a coffee brewing method, like grinding your beans and keeping your equipment clean.

The easiest way to stop your Moka Pot from leaking from the middle is to ensure there is no gap between the top and the bottom chambers. You may need to use more force than you think is necessary to tighten them, especially if you are new to brewing with a Moka Pot.

As frustrating as Moka Pot is leaking water, it’s a good sign that the safety valve is doing its job. Without it, excessive pressure could build up in the coffee maker while you brew, potentially causing a messy and dangerous explosion! To prevent this problem, always watch where the pressure valve is located in your Moka Pot’s bottom section, and fill no higher than that.

Even if you haven’t quite gone over the safety valve, too much water can lead to coffee bubbling over the top of the coffee brewer. While this isn’t technically a leak, it’s still likely to create a mess that needs to be cleaned in your kitchen.

To avoid spilling, keep the water level a bit below the bottom of the safety valve. Keeping the lid of the Moka Pot open while you brew coffee can also help you see what’s going on. Finally, take the coffee brewer off the stove burner before it bubbles out the spout.

Coffee that’s too finely ground can block water movement through the coffee grinds. In the best-case scenario, you’d get burnt coffee full of bitterness. When water can’t get where it needs to go, you will likely have a Moka coffee pot leaking.

However, putting milk in a Moka Pot is a bad idea because it will likely clog your coffee maker. As a result, it may start leaking. To ensure your Moka Pot works properly, do not put anything other than water and coffee grounds inside it when you are brewing coffee.

Many prominent manufacturers of Moka Pots, such as Bialetti, sell replacement gaskets for their devices. That way, you don’t have to get a whole new pot if you have a Bialetti leaking due to one damaged component.

If you bought an off-brand Moka Pot to save money, you might find purchasing replacement gaskets and other parts more difficult. It can be important to consider if you are trying to choose between Bialetti Moka Pot and its cheaper competitors. Spending more on your initial investment can mean you don’t have to buy a new Moka Pot later.

A final scenario that could lead to a leaking Moka Pot, though it’s less plausible than most other reasons, is a crack in your Moka Pot. In that case, it will leak from the Moka Pot’s crack rather than the valve or the center.

After extensive usage or due to use of wrong ground coffee and/or scale water, your Brikka might get clogged, release pressure through the valve or between parts, use only part of the water etc. It will stop acting normally and will not produce your favorite Moka.

Prepare your Moka and see if all is working as expected, coffee is flowing freely, crema is built and no pressure leaks from the pressure valve or between water and coffee containers.

Turns out, the new gaskets that Bialetti sells (at least here in Greece) are different from the older ones. The new gasket is a simple white sort-of washer, while the older one had a groove in the outer rim, which ensured a snugger fit and kept the filter firmly. Now with the new gasket, the filter can be turned more easily, still I tested it and it produced a fine brew.

A moka pot is a great tool but there’s also a bit of a learning curve to get the best results. You might have noticed coffee leaking from the wrong places.  What’s the problem and how can you stop this mess from happening?

The biggest reason for a moka pot leaking is that the upper collector isn’t screwed onto the boiler tightly enough or something is stuck in the thread. Another common problem is that the rubber gasket that sits between the filter basket and filter lid is damaged or sits in the wrong location.

Pressure will always find the path of least resistance to get out. So if the coffee finds less resistance by leaking out from the connection, it will leak out there and not get into the collector because making its way up the pillar and into the collector is more resistive.

The simple solution is to just screw it on tighter. Hold both the boiler and the collector and screw it on until it stops moving. It shouldn’t take hulk strength to stop leaking. The collector should screw on most of the way without much resistance. Once you hit the part where there is resistance, you should be almost there, just twist it a little further with medium strength and it should seal properly. Once it stops turning, don’t over-tighten it because you could damage the thread.

The rubber ring is supposed to sit between the filter basket and filter lid to force the coffee through the filter without leaking out the sides of the filter.

If the thread is damaged and any of the other tips don’t work to stop your moka pot from leaking, just replace it. There is no way to properly fix it in a way that’s worth your time.

If water is coming from the pressure valve in your moka pot, it’s likely that it’s dirty and residue is stuck in there that prevents the valve from opening and closing properly. Coffee residue and mineral deposits from hard water settle all over a moka pot and also in the safety valve.

First, see if you can move the valve by hand with the help of a pen or small tool. See if you can get it to move. If it does, just moving it around might break up some of the residue.

If you moka pot is quite old and cleaning doesn’t work, it’s possible the valve is just worn out. There is a small rubber o-ring in the valve. Just like any other rubber parts, the harden and break down over time. Once that happens, the water can just get through the valve because it’s not sealed off properly.

For some of the high-end moka pot brands you could find a replacement valve but you’ll have to see if the price of the replacement part is worth it compared to just getting a new pot.

If you have a solid jet of water shooting from your safety valve, you might just have filled the boiler too much. Just fill the water level in the boiler to just under the safety valve.

If all other options aren’t what is leaking the last option is the boiler itself. It’s very unlikely to happen but maybe if you drop your pot repeatedly some place could crack and start leaking. Inspect it closely and if you can find any cracks, it’s game over. Just get a new moka pot.

If you can’t find any visual cracks, fill it up with water (below the pressure valve) and leave it alone for a day. If you can find any water leaking out, it’s finished.

Moka Pot: Just buy a high quality Moka pot from the get go. The cheaper ones can be messy when brewing. Bialetti is the original and still one of the best with it’s classic looks. They cost a bit more than the cheap ones but these can last for decades and the parts that wear out are easily available for the Bialetti Moka pots.

The most common reason for a leaking moka pot is that the top and bottom chambers are not tightly screwed together. Other causes are that the pieces are not threaded or aligned correctly, the rubber gasket is damaged, or the grind size is too fine.

Most people will experience a leaking moka pot at one point or another because they forget to tighten the chambers tightly enough. This probably won’t happen too often though.

A moka pot may also leak out of the pressure valve if the internal pressure rises above 3 bars. This will usually only happen if something is clogging the moka pot and preventing the steam to release upwards into the upper chamber.

In this case, a leaking moka pot is inevitable because it won’t matter how tight the moka pot is screwed together. A fault rubber gasket will prevent your moka pot from having a secure seal that is able to withstand the internal pressure cause by the brew.

Make sure your grind size is not too fine. It should be slightly more coarse than an espresso grind. This will reduce the internal pressure and prevent the pressure valve from going off.

If your Moka Pot is leaking, apply some vegetable oil to the screws and twist the top on and off multiple times before wiping clean with a clean cloth. This creates a softer surface and, in most cases, prevents leakage. It is much simpler to clean your Moka pot on a constant schedule; in that manner, you won’t have to struggle with a clogged device and leaking issues!

The number one reason your Moka pot is leaking is that the rubber gasket isn’t sealing properly. Over time, the gasket will become harder and won’t create a proper seal. This will cause the hot water to seep out of the pot and make a mess.

Another important reason your Moka pot might be leaking is that the screws are loose. If the screws are loose, they won’t create a tight seal, and water will leak out. Make sure to check the screws on your Moka pot regularly and tighten them if necessary.

If your Moka pot has a safety valve, make sure that it’s working properly. The safety valve is there to release the pressure if it gets too high. If the valve is not working properly, it can cause the Moka pot to leak.

There are a few things that can happen when your Moka pot is leaking. First, you may notice that your coffee isn’t as strong as it usually is. This is because the water is leaking out of the pot, so there’s less water to extract the coffee oils from the grounds.

If none of the preceding solutions have worked, try using coarser coffee grounds. We hope this list helps you or even our tips might help with any leaking issue!

Exploding coffee makers—especially when they’re pressurized—tend to be day-ruiners. Yeah, cleaning isn’t that fun, but trust me…. it’s necessary, especially when it comes to moka pots. Safety and cleaning are actually interconnected with this brewer.

Now, moka pots do have asafety valvethat’s designed to keep too much pressure from building up in the device. Once more pressure than is necessary is generated, it starts to shoot out of the valve in the form of steam.

The valve is clogged with coffee grounds. If grounds happen to fall into the valve, they’re probably going to get stuck there. Over time, this can cause blockage in the valve and compromise its safety.

The valve is clogged with water gunk. If your local water source is ‘hard’ (has a high level of calcium and magnesium), you’re bound to see white gunk build up inside your moka pot over time. This gunk can be pretty stubborn and can clog the safety valve.

You covered the safety valve with water. Over-adding water can cover the safety valve, which keeps it from being able to let out steam. Always leave a small amount of space between the water level and the safety valve.

Over time, coffee oils and micro-grounds build up all over the insides of the moka pot. These are harmless when it comes to your health (unless those grounds are in the safety valve), but they do impact your brew’s flavor. Those old oils can go rancid and the grounds continually impart bitter flavors into later brews.

Add lots of water. Fill the lower chamber, cover the safety valve, and keep adding until the water line hits the coffee filter basket (that way the oils can be cleaned from there at the same time).

Pour out some of the water. Make sure the safety valve is no longer covered—you’re about to do a plain water brew cycle and want the valve to work if needed.

While the process takes a few hours overall, there’s really only 5-10 minutes of hands-on cleaning—and it goes a long way. Now your brew will be untainted by old grounds, your moka pot won’t have a faulty valve, and you can brew will complete confidence.
