The brewing process heavily relies on hot water. Hot water infuses into your coffee grounds, drawing out their essence and creating your ideal cup of coffee.


This process doesn’t work well with cold and lukewarm water. Thankfully, your coffee maker is built with a heater that brings water from the reservoir to the ideal brewing temperature.

As such:

Heating water from the cold water reservoir is an important step in brewing. So it can suck when the water in your Keurig coffee maker isn’t heating.


This isn’t a hopeless situation. Here are a few possible causes for your Keurig’s heating problem.

Keurig Isn’t Heating

It’s safe to say you can’t brew coffee without hot water, with the exception of a cold brew or a frap. The heat helps when brewing, and your coffee maker is meant to facilitate cold water heating. If your coffee maker isn’t heating, you can check the heating light, the water pump, or the heater.

1. The Heating Light Isn’t Coming On

Your Keurig coffee maker has different ways of helping you follow the brewing process. It varies depending on your model, but it is usually evident.


Most Keurig coffee makers have a heating light. This lets you know when your coffee maker is heating water from the reservoir.


If the light isn’t coming on, or stays on and refuses to switch to brewing, you may have a problem with your coffee maker.


This occurs commonly and has a straightforward troubleshooting method. You can remedy this problem by following the steps below.

  • Step 1: Turn off your coffee maker and unplug it from the power socket.
  • Step 2: Carefully remove the cold water reservoir and empty it into the sink. Set it aside.
  • Step 3: Plug your coffee maker back in and place a cup on the drip tray.
  • Step 4: Make sure the machine is off and hold the brew button.
  • Step 5: Hold the brew button down until your coffee maker stops dripping.
  • Step 6: Refill the water reservoir and turn your machine back on.

This will empty the hot water reservoir within your machine. Your coffee maker will have to heat a new batch of water, and the brewing process should continue uninterrupted.

2. The Pump is Faulty

Here’s the thing:

Your Keurig coffee maker is a lot more sensitive than you think.


Your coffee maker was constructed in a way that internally regulates many factors you normally ignore.


One such factor is the internal temperature of the machine. You see, your coffee maker majorly consists of electrical parts and needs to avoid overheating.


It regulates its temperature by circulating cold water from the reservoir.

As such:

The heater will stop as a failsafe if the water pump isn’t functioning as it should. Consequently, water must flow into your coffee maker for the heater to work.


You may be able to fix this problem by using the turkey baster method. This will work if there is something obstructing water flow within your machine.


If your pump itself has stopped working, contact Keurig customer service for more troubleshooting options.

3. The Heater is Faulty

Water is heated in a small compartment in your machine. It is large enough to accommodate the right amount of water for brewing.


A faulty heater will not heat your water. If this part develops an issue, it can greatly affect the brewing process.


This is a highly technical part of your Keurig brewer. Do not attempt to fix it if you do not know what you are doing.


Contacting Keurig customer service is the safer bet. They will either hook you up with a new part, fix the existing one for you, or recommend a new coffee maker if necessary.

4. A Coffee Maker Reset is Required

If all else fails, you can try resetting your Keurig coffee maker.

You see:

Your heater or water pump may have incurred a slight electrical fault due to an interrupted brew. There are also other small incidents that a quick reset can fix.


You can reset your Keurig coffee maker by following the steps below.

  • Step 1: Power down your coffee maker by holding the power button.
  • Step 2: Unplug it from your power socket and carefully remove the cold water reservoir.
  • Step 3: Set the water reservoir aside and allow your coffee maker to sit for at least thirty minutes.
  • Step 4: Reassemble the coffee maker and brew normally.

This should give your machine enough time to roll back any minor electrical faults incurred. Hopefully, this fixes the heating problem and lets it brew normally.

Models Commonly Affected

You see:

Any Keurig coffee maker could suffer from this heating problem. It largely varies from user errors to faulty machine parts.


There are a few models that are usually associated with the issue.

1. Keurig K40

The Keurig K40 has a few indicator lights that help monitor the coffee maker’s condition.


It also comes with a heating light. As such, it can suffer from a heating problem if the light isn’t coming on during the brewing process.

2. Keurig B60

Keurig B60

The Keurig B60 is an older model single-serve coffee maker.


The internal heater on this model can sometimes stop working and may require a replacement or a fix.

3. Keurig B150

Keurig B150

The Keurig B150 is a commercial model and is made to brew multiple times if required.


This can wear down both the water pump and the heater.

As such:

Do not be surprised if the B150 no longer heats water or stops brewing entirely.

Other models that can develop this problem short term or in the long run include the Keurig 2.0, Keurig K40, the Keurig Duo, the Keurig Mini, the Keurig Single, and the Keurig B70.


Your Keurig needs hot water to brew a hot cup of coffee.

As such:

A faulty heater or pump is not a problem you can overlook.


You can remedy this issue by trying the below listed possible solutions.

  • Make sure the heating light is functional and on.
  • Check the water pump and replace it if necessary.
  • Check that the water heater isn’t faulty.
  • Reset the coffee maker to be on the safe side.

Remember that:

Your coffee maker is designed to mitigate as much damage as possible. Getting to the bottom of this could save you a lot of future repair costs.
