Keurig Stuck on Preheat - What to Do?

Is your Keurig stuck in the preheating cycle? The most probable causes are the water pump or a blockage. While a malfunctioning water pump can cause your Keurig to continue cycling through the preheating process, you don't want to jump immediately to that conclusion.

The first thing you should do is check the water nozzle. It's possible that it may be clogged with coffee grounds or other debris. If this is the case, it's a really easy fix. You can use a needle or similar object to dislodge whatever is blocking your nozzle. However, this could be dangerous. Once the blockage is removed, the hot water will likely pour out onto your hand. Make sure your Keurig is turned off and unplugged to avoid this scenario.

If you have the Keurig 2.0, the best way to unclog your water nozzle is by using the tool that Keurig has designed specifically for this purpose. This will be safer, helping you avoid spewing water or getting poked by a needle.

If you are still experiencing problems after unclogging your water nozzle, you should contact Keurig support because you may need a new water pump.

Why Won't My Keurig Heat Up?

Is your Keurig going through the motions only to give you a cup of cold or lukewarm coffee? Don't panic just yet. This could be a very simple fix. According to Keurig, if the coffee is warm but not as hot as expected, it could be due to the type of cup you are using.

Types of Cups

Foam and paper cups work as insulators, keeping your coffee hot. However, ceramic and glass cups may be cold before brewing, dropping the temperature of your coffee when it hits the cold cup. Keurig troubleshooting recommends running a cup-cleansing brew when you first turn on your Keurig. This allows both the cup and the Keurig to properly heat up.

Keurig Needs Cleaning

With the quick and easy process involved in using a Keurig, you may forget that, like original coffee makers and pots, it needs to be cleaned regularly. If you don't keep it clean, your machine will develop calcium build-up. Without a regular cleaning routine, your Keurig will likely become clogged with dried coffee grounds as well. Both calcium build-up and a machine clogged with coffee grounds can cause your Keurig to stop heating up.

You can quickly and easily clean your Keurig with descaling pods.
