Is your coffee maker leaking? Something inside it could be broken. Follow these 4 steps.

Having your coffee maker flood your kitchen countertop is a nightmare. All you wanted for your morning was a nice cup of coffee, and instead you ended up having to sweep the kitchen floor. Sounds familiar?

There are many reasons why this might be happening to you. From an internal obstruction, to a broken component. It’s really anyone’s guess. That is, if you don’t have a detailed list of what the culprits might be, and the steps required to fix them.

Lucky for you, I’ve prepared one below.

To fix most of these issues, you won’t even have to buy a replacement. You’ll just need to get some vinegar and clean your appliance. That being said, there is a small chance you might have to open your coffee maker and expose the wiring, but don’t worry, that’s not nearly as intimidating as it sounds.

All set? Let’s begin!

The Steps to Follow Are:

  1. Check your pot for cracks
  2. Check for clogging
  3. Inspect your coffee maker’s hose
  4. Check your valve pump

I want to make this process as simple as possible for you, which is why the first two steps will not require you to open your appliance, but you should have a screwdriver and some pliers handy, just in case.

#1 Check Your Pot for Cracks

Besides obvious accidents, there are other things that cause coffee pots to crack. One of the most common is dramatic and sudden changes in temperature.

The cracks on your pot can be nearly invisible

I know, I know. This sounds like something very obvious, but sometimes small pot cracks are very easy to miss. I’m not talking about quarter sized holes in your recipient, I’m talking about hairline fractures.

Believe it or not, even a very thin crack could be causing your leakage, especially if you leave your coffee maker unattended for extended periods.

While it’s true that the tempered glass in your coffee pot makes it very resistant, extreme temperatures or pressure buildup can crack it over time. Steam can create enormous amounts of pressure within your pot, so watch out for buildup. It can be catastrophic.

Solution: The simplest solution would be to get a new coffee pot; however, if you’re too attached to yours or simply don’t want to spend that money now, there are always other options.

5-minute epoxy has been known to work great to fix these cracks, as it is temperature and moisture resistant. All you have to do is apply it to the cracks you identify, and let it rest.

If that doesn’t sound like something you want to try, there are different fixes out there.

#2 Check for Clogging

Cleaning your coffee maker every other month is not only advised, but necessary to keep you from drinking harmful chemicals. Depending on where you live and the quality of the water you use to brew your coffee, this issue could present itself more quickly.

As you probably know, in order to brew, your coffee maker passes hot water through the coffee grounds of your choice, and onto the pot.

Over time, this process can contribute to the formation of sediment, which can obstruct the passing of water and cause it to leak. So, if you’ve neglected cleaning your appliance for a while, this is probably the issue.

Solution:  Luckily, addressing this is very simple, all you need is a bit of water and some vinegar.

To get rid of the sediment stuck within your coffee maker, you’ll have to combine both ingredients in equal parts and pour the mixture into your water tank. Once you have done that, run a regular brewing cycle. This is known as descaling.

Depending on how severe your particular obstruction is, you could see water coming out to the pot right away, or within 20-30 minutes. The vinegar will break down all the unwanted elements that are clinging to the internal components of your coffee maker.

If your coffee tastes somewhat vinegary after performing this process, just put some water in the tank and do a couple more brewing cycles to get rid of the taste.

#3 Inspect Your Coffee Maker’s Hose

Check for a broken hose

The hose within your coffee maker is responsible for transporting the hot water from your water tank, onto your ground coffee beans, and finally down to your pot. Logically, when it breaks, you’re going to have leaks everywhere.

If you haven’t descaled your coffee maker in a while, this could be a blessing in disguise. Sometimes, there’s just so much sediment built up in your hose, that no amount of vinegar can safely remove it. So cheer up. It’s not all bad news!

Solution: If neither of the previous two steps fixed your problem, you’re going to have to go in. Don’t start sweating buckets, thought, it should all be fairly simple and run smoothly.

First, unplug your coffee maker and locate the screws that will let you access its guts. Normally, they’re either at the top, or at the bottom. Remove them to expose the hose and all other internal components of your appliance.

Lastly, carefully remove your hose (it should come off easily) and check for leaks. If there are any, it’s time to replace it. You can get another one for less than $20 at any online marketplace.

 #4 Check Your Valve Pump

Coffee grounds can become an obstruction

I’ve kept the most complicated step for last. Now, there’s no reason to panic. When I say complicated, I don’t mean rocket science, I just mean you’re going to have to do some scrubbing at best. Relax!

Your coffee maker’s valve pump is usually located within your hose. This nifty little piece of equipment is responsible for making sure that there is an adequate flow of water throughout the brewing process.

As time goes by, coffee grounds and/or sediment can stick to your valve pump and compromise its functionality. This could explain your leakage problem.

Solution:  Since you already removed the screws and exposed your coffee maker’s guts, this should be fairly simple. All you have to do, is locate the valve within your hose, remove it, and scrub the impurities off with a toothbrush.

In the case that your valve is broken or otherwise compromised, you’re going to have to get a replacement.

All done!

Conclusion

 A leaky coffee maker can make a mess, fast.

More often than not, the reason behind the occurrence is not a faulty component, but rather a broken pot or clogging derived from poor maintenance.

Knowing your way around your coffee maker, and understanding its components, can save you a lot of time and headaches. The same goes for cleaning it every other month and descaling it with vinegar to make sure there’s no sediment build up.

That being said, proper maintenance also includes looking out for your own safety. Always remember to unplug your coffee maker from the wall outlet and turn it off before tempering with its internal components.

Moreover, there’s no shame in feeling overwhelmed. If at any point during these steps you feel doubtful, do not hesitate to call a trusted technician, and have them help you out.
