Mr. Coffee Beeps 3 Times And Won’t Brew (Troubleshooting!)

It’s normal for your Mr. Coffee machine to beep one time when it has finished brewing. But when it beeps 3 times or more there is something wrong.

This can be frustrating, especially when you’re in need of your morning caffeine fix. In this article I listed some possible solutions to help you troubleshoot this issue.

How To Fix A Mr. Coffee That Won’t Brew And Beeps 3 Times?

You’ve got your Mr. Coffee machine that loves to beep three times then goes on strike, no brew, nothing. The 3 beeps can have a few different causes:

  • Components are not properly in place.
  • Clogged tubes inside the machine.
  • Potential fault in the hot plate.

Let’s dive deeper into how to fix these issues.

Mr. Coffee Beeping 3 times

Ensure All Components Are Properly Seated

In my experience, the most common reason that can cause your Mr. Coffee machine to beep three times and fail to brew is if the carafe, the filter basket, the lid, or the water reservoir are not correctly positioned.

The machine has a built-in safety feature that beeps three times to alert you to this issue, preventing it from brewing until all parts are properly seated.

here’s how you can address it:

  1. Make sure the carafe is correctly placed on the warming plate. Ensure it sits flat and is centered correctly.
  2. Check the filter basket. Ensure that it is securely inserted in its compartment.
  3. Close the lid all the way.
  4. Verify the water reservoir is appropriately filled and properly closed.

Sometimes, in the rush of brewing a pot of coffee, you might accidentally trigger the start button before all the components are ready. Wait for a few seconds after ensuring everything is in place before pressing the start button.

This simple fix could potentially solve your problem and allow you to enjoy a fresh brew without any further inconvenience.

Clear The Clogged Tubes

Another thing that can cause your Mr. Coffee to beep three times are clogged tubes inside the machine. To fix this issue, I took the following steps:

  1. Unplug the coffee maker and let it cool completely to ensure safety.
  2. Unscrew the bottom of the coffee maker using a small Phillips head screwdriver.
  3. Use pliers (needle nose type would work well) to remove the wire clamps holding the silicone water tubes to the hot plate.
  4. Inspect the water line running from the reservoir to the hot plate for any visible blockages. If you find something, gently remove it.
  5. If nothing is visible, try blowing into the hose to remove any potential invisible blockages like scale or grounds.
  6. Once the line is clear, clean it using vinegar to remove any residual build-up.
  7. Reassemble the machine.

After unclogging the tubes, it’s a good idea to run a descaling cycle to make sure all the mineral buildup gets rinsed out of the tubes. Here is how to do that:

  1. Make sure the carafe is empty and the coffee maker is turned off. Remove any leftover coffee grounds from the filter basket.
  2. Mix equal parts of white vinegar and water. This will be your descaling solution. If your coffee maker has a 12-cup capacity, mix 6 cups of white vinegar with 6 cups of water.
  3. Pour the vinegar solution into the coffee maker’s water reservoir.
  4. Place the carafe back on the warming plate and start a brew cycle. Allow the machine to run a full cycle with the vinegar solution.
  5. Switch the machine off halfway through the brewing cycle and let it sit for 30 minutes. Then, switch it back on and finish the cycle.
  6. After the cycle with the vinegar solution is complete, empty the carafe and fill the reservoir with clean water. Run a full brew cycle with just water to rinse out any residual vinegar solution. You might want to do this a couple of times to make sure all traces of vinegar are gone.
  7. Use a clean, dry cloth to wipe down your coffee maker, paying special attention to the area around the lid and the exterior of the pot.

The Hot Plate Workaround

If the previous methods don’t work or if the problem lies with the hot plate. Follow the below steps:

  1. Brew your coffee as usual.
  2. After starting the brewing process, add a small amount of water to the hot plate, making sure that it doesn’t overflow.
  3. The coffee maker will then brew a complete pot of coffee and keep it hot.

Note that this method should only be a temporary solution and the machine should be turned off manually when done brewing. This is because overriding safety features is potentially risky.

Mr. Coffee Beeping 5 Times

If your Mr. Coffee coffeemaker is beeping 5 times instead of 3, it could be an issue with the fuse, the heating element, or the temperature switch. And you might have to replace one of these components.

If you’re handy with electronics, then this shouldn’t be too hard. Here is a video explaining the problem:

Considering A New Coffee Maker

If your machine is still under warranty, consider reaching out to Mr. Coffee for a replacement or repair.

If not, and none of the above solutions have helped, it might be time to consider purchasing a new coffee machine.

You could purchase a brand new Mr. Coffee machine for the same amount you’d typically spend on coffee in a single month.

Another great option, if you want to spend a bit more for some more functionality, is the Ninja Programmable Brewer.


The beeping of your Mr. Coffee machine is usually a sign of simple issues like misplaced components, clogged tubes, or a problem with the hot plate. These can often be resolved with careful inspection and cleaning.

If issues persist, consider contacting Mr. Coffee if your machine is under warranty or perhaps invest in a new coffee maker if your warranty has expired.

Ultimately, ensuring your coffee machine operates efficiently is key to a reliable, enjoyable morning brew.
