Keuirg not heating water. Troubleshoot

The temperature of coffee preparation is essential for its flavor. Even a small decrease in temperature can have a big impact. The ideal water temperature is 198 degrees Fahrenheit, allowing the desired flavors of the ground coffee to be extracted and producing a balanced cup. If the temperature drops below 194 degrees, it results in an under-extracted coffee with poor taste.

If the temperature is too low, there is a sharp drop in the taste, accentuating the feeling of a cold coffee.

Even a slight decrease of 7 or 8 degrees can significantly impact the coffee flavor. The end result is a cup of coffee that is not at its best and does not provide a satisfying flavor experience. Therefore, it is important to pay attention to the temperature of coffee preparation to ensure a well-prepared and delicious cup of coffee.

Issues with the cup size

Keurig coffee makers are specifically designed to brew coffee in certain cup sizes. If a larger cup than the machine is intended for is used, it may not provide enough time for the water to heat properly before it is dispensed. This can result in the coffee being lukewarm or cold.

Therefore, using the correct cup size for the Keurig coffee maker is important. However, this should not be a problem if the machine is not experiencing the two issues discussed below:

Issues with clogging of the Keurig injector

If the needles of the Keurig coffee maker become clogged with coffee sediments or minerals, the water cannot flow correctly through them. This can cause slower brewing, and, as a result, the coffee will be less hot.

Regular cleaning of the needles is essential to avoid this problem. This can be done by using a cleaning solution or running a water cycle through the coffee maker without a K-Cup.

Descale your Keurig

If the Keurig coffee maker is not regularly cleaned, coffee sediments or minerals can accumulate in the machine. This can affect its performance and ability to heat the coffee properly.

To maintain proper functioning and avoid temperature problems with the coffee, cleaning the coffee maker regularly, including descaling, is crucial. Descaling removes the buildup of minerals and sediments, which can affect the coffee’s taste and the coffee maker’s longevity.

Problems with the thermal switch or heating element

If the water temperature does not reach the correct temperature at the heating element, the coffee in your cup will seem cold, and its taste will not be good. This could be caused by a failure in the coffee maker’s heating element, although this is quite rare as these devices are very simple.

A leak in the heating element could cause a lack of temperature, but this would be a completely different issue we have already addressed HERE.

The most common issue is a failure in the coffee maker’s thermal switch, which is responsible for opening and closing the circuit that allows the coffee maker to heat the water. The water will not be heated enough if the thermal switch opens the circuit below the correct temperature. In these cases, the solution would be to replace the thermostat.

➡️ If the thermal switch malfunctions, the coffee may come out completely cold, or the Keurig may not brew at all, as it prevents operation when the thermal switch is not functioning correctly.

Methods to improve the temperature of your Keurig coffee

If you’re finding that your Keurig coffee isn’t as hot as you would like it to be, you can try a few tricks to increase the temperature and keep it hotter for longer. Here are some alternatives if you’re looking for a hotter cup of Keurig coffee:

  1. Preheat your Keurig machine: Run plain water through the machine for one cycle without inserting a K-cup pod. This will help raise the machine’s temperature, and your coffee will be hotter.
  2. Preheat your mug with hot water before pouring coffee into it, especially during colder months. This will prevent the coffee from immediately losing heat when it comes in contact with the cold mug.
  3. Use a stainless steel travel mug: Stainless steel travel mugs are excellent at retaining heat. They can keep your coffee hot for several hours.
  4. Use a cup warmer: If you have a cup warmer, use it to keep your coffee warm for longer. Place your mug on the warmer, and it will maintain a constant temperature.
  5. Avoid using paper or foam cups: Paper or foam cups can significantly lower the temperature of your coffee. If possible, use a ceramic or glass mug with a lid.
