Possible Causes of the Issue

There are several reasons why your Keurig K-Supreme Plus may not be brewing a full cup of coffee. Some of the most common causes include:

Insufficient water level in the water reservoir: If the water level in the reservoir is low, your Keurig may not be able to brew a full cup of coffee. Make sure to check the water level and refill the reservoir as needed.

Clogged or dirty needle that punctures the coffee pod: Over time, the needle that punctures the coffee pod can become clogged with coffee grounds or other debris, which can cause the machine to brew less coffee. You can clean the needle by using a paper clip or Keurig’s needle cleaning tool.

Incorrect brewing setting: If the machine is set to brew a small cup of coffee, it will only dispense a small amount of water, which can result in a less than full cup. Check and adjust the brewing setting to ensure the right cup size is selected.

Malfunctioning water pump or valve: If the water pump or valve is malfunctioning, the machine may not be able to dispense enough water to brew a full cup of coffee. In this case, it may be necessary to replace the damaged parts.

Other potential causes: There are several other potential causes of the “not brewing full cup” issue, including mineral build-up in the machine, a malfunctioning control board, or a damaged reservoir float.
