Is your slow cooker leaking water? It might be due to a small crack or even misuse. Here’s how to find and fix the leak.

There are many mishaps that can happen in the kitchen, but very few are as frustrating as a leaking slow cooker.

Coming home to a flooded cook top and a wasted meal can ruin anyone’s day. If this has happened to you before, there’s probably an issue with your slow cooker’s body or lid.

Worry not, though. In most cases, these imperfections can be fixed in a jiffy.

Below, you’ll find a list of the possible causes to this inconvenience, how you can address them, and some suggestions in case your warranty has expired.

Let’s get to work and contain the flood!

Your Slow Cooker Could Be Leaking Due To…

  • Overfilling
  • A damaged lid rubber
  • A broken pot

There are many possible causes behind the leaking, each a bit more complex than the previous one. But rest assured, that when I say “complex”, I don’t mean rocket science. You’ll just need to buy a couple of things.

Moreover, if your slow cooker is not older than a year, there’s a very big chance that you’re still under warranty coverage! That will make things a lot easier. But don’t worry if this is not the case, you still have a lot of options if your warranty is expired.

Why does my slow cooker leak? The most common reasons are issues with the rim of your lid or with the gasket that seals it closed. Check all the reasons below!

#1 You’re Overfilling Your Slow Cooker

Always  keep your slow cooker below ⅔ of its maximum capacity

I’d love to start this list off with this possible cause, which is not even a technical issue, but rather a more user-related mistake.

Hey, I don’t blame you! To be honest, I also skim through the user manuals of my appliances every now and again.

It turns out, most manufacturers recommend not filling your slow cooker beyond 2/3 of its maximum capacity, as this can cause overflowing and leaking. Remember that cooking releases steam and causes condensation, which, when combined with overfilling, can cause your slow cooker to spill.

Solution: Fortunately, to fix this issue you need no replacements, warranty coverage, or the help of a technician. All you have to do is make sure you’re following the 2/3 rule of thumb mentioned above, and you should be fine.

Problem solved.

#2 Your Lid’s Rubber Is Damaged

If your lid’s seal is compromised, leaking will occur

This is where things start moving away from user-related issues, and towards normal wear and tear factors.

Depending on how often you use your slow cooker, the rubber ring on the lid, which is responsible for creating the seal, might be damaged or worn out. This is considered normal, as components like these are expected to last only for so long.

If your rubber lid seal ring is broken, bent or otherwise damaged, that could explain your leaking problem.

The great news is that replacing this part is super simple!

Solution: Depending on your warranty’s coverage, you can either have it replaced by your manufacturer, or do the job yourself.

Since this is such an easy and quick fix, I’d recommend trying to do this on your own.

Especially considering that sending your slow cooker to the manufacturer can take days or weeks.

The replacement process is almost identical for several kitchen appliances, so don’t be afraid to follow the instructions for a pressure cooker, for example. You can find your new rubber lid seal at online marketplaces for about $15.

#3 Your Pot Is Broken

Cracked Slow Cooker Pot
Although slow cooking is very safe, a few things can cause a ceramic or stoneware crock to crack.

Watch out for hairline fractures on your pot

This is one of those things you can easily miss.

The problem with broken slow cooker pots is that even a hairline crack can cause them to leak.

Now, while this could be the issue, having it happen is not that common, since slow cooker pots will normally only break if:

  • They experience sudden temperature changes
  • You put them on the stove burners
  • You lay them down carelessly

So, try not to go all Hulk on them when cooking!

The good news is that fixing this problem is not very difficult, you can even do it at home if you can spare an hour or two.

Solution: You have two routes you can take to address this issue.

If you’re still within your warranty coverage, you can send your slow cooker to your manufacturer to have it fixed or replaced. But if your warranty is expired, there’s still hope!

If your slow cooker is made from ceramic, you can buy 5-minute clear epoxy and patch it up. This material is normally heat and moisture resistant, which makes it perfect to repair those annoying small cracks.

When to Use Your Warranty?

Throughout this list, we’ve talked about deciding whether to send your slow cooker to your manufacturer for repairs, but how viable is it really? The short answer is…it depends.

Most slow cooker manufacturers will issue a 1-year warranty, so, if yours is older than a year, you’re probably not covered by it anymore.

That is, unless you bought an extension. If you did, great, but if you didn’t, you still have a lot of cheap and quick options available to you.

I’m Still Within Coverage, When Can I Send My Slow Cooker In?

Most manufacturers will happily replace your slow cooker or its components if they’ve failed under normal operating conditions. That means, that they will take care of the repairs if your appliance failed while using it according to their instructions.

Commonly, manufacturers won’t accept cracked pots or damaged components if they were dropped, placed over a burner, or used otherwise incorrectly.

For example, if your slow cooker’s pot cracked because you accidentally placed it too hard on the counter, you’re unfortunately out of luck. Bummer.


Having your slow cooker leak can ruin your day.

There is just no possible way to use a slow cooker to make a meal when the contents of it keep overflowing and making a mess on your cook top.

As we’ve discussed, on many occasions, the slow cooker could be perfectly fine, it just needs to be a bit emptier to stop it from leaking. And even when the problem is actually technical, most fixes are quick, cheap and simple.

Every year, thousands of slow cookers are sent back to manufacturers for repairs that the owners could have performed themselves.

I cannot stress this enough, even if you’re still under warranty coverage, there are only a handful of reasons to send your slow cooker in for repairs or call a technician.

Most of the time, a new rubber lid seal or some clear 5-minute epoxy will do the trick, saving you time and money, and getting you back to cooking the very same day.

That being said, if you’re not 100% confident that you can fix your slow cooker on your own or don’t want to void your warranty, it’s totally ok to ask for your manufacturer’s or technician’s help. All that matters is that you stay safe and are able to enjoy the wonderful meals your slow cooker can prepare for you.
