Why is my Bunn GRX Coffee Maker coffee cold?
- LLaura FernandezAug 14, 2025
If your Bunn Coffee Maker is producing cold coffee, ensure the brewer is plugged in and the vacation switch on the side is turned on, allowing 15 minutes for the water to reach the correct temperature. For BX, GRX, and NHBX models, check that the warmer switch is in the “on” position. If you have a BTX model with a thermal carafe, pre-heating it will help keep your coffee warm longer.
