Reasons Why Mr Coffee Won’t Brew and What to Do

Here are some of the most common reasons why a Mr Coffee won’t brew and what you can do about it.

No Power Supply

If there is no power supply, your Mr. Coffee won’t brew. Actually, it won’t even start.

Start by ensuring that the power supply switch is on. Then, check whether the light of the coffee brewer is on. If it’s on, then there is no problem with the power supply. If the light is off, check the plug and ensure it’s properly connected to a power source.

Damaged Power Cord

A damaged power cord may also be the culprit behind your Mr Coffee, not brewing. When a cord is damaged, it cannot transmit power to the coffee maker, making it impossible to brew coffee. One of the signs of a damaged power cord is the machine turning on and then shutting off unexpectedly.

Sometimes, the damage can be visible. The cord may also look fine but still has a problem that prevents it from functioning properly. The only solution to this problem is getting another cord.

Inadequate Water Levels

If the coffee maker is beeping but not brewing, the issue can be related to the water level. Ensure that the water inside the water reservoir is enough. Then, try brewing and see whether it works.


If you haven’t deep cleaned your coffee maker for a while, it could be why it’s not brewing. This can happen if it gets clogged by calcium and hard water deposits. These deposits affect water flow, making it impossible for the coffee maker to brew.

To clean the machine, add five cups of white vinegar to the glass pot, then hold the start button for two minutes. Pour the vinegar through the filter when the machine starts to heat. Finally, rinse it using water.

If you do not have vinegar, you can still clean your machine without vinegar.

A Faulty Warming Plate

If the warming plate of your Mr. coffee is faulty, it won’t brew coffee. Unfortunately, a faulty warming plate can only be replaced for your machine to continue functioning.

 If you have tried the other methods and your coffee maker is still not working, have the warming plate checked and replaced if it’s faulty.

Unbalanced or Off-Centered Filter

An unbalanced or off-centered filter is another reason your  Mr Coffee can fail to brew. If this is the cause, you need to reposition the filter as you open the top lid of the machine.

Mr. Coffee Pot Beeping

If Mr Coffee pot is beeping but doesn’t brew, it could be that the water reservoir is full or the parts are not nestled correctly into their nooks.
