    Why is my Bunn Coffee Maker coffee cold?

      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.

      If your Bunn Coffee Maker's funnel is overflowing, make sure the lid is fully open. Note that the brewer isn't designed to hold water in the upper tray for a long time. Also, remove the top lid to check that the rocker arm is correctly snapped in place and the rubber stopper area is thoroughly cleaned.

      If your Bunn Coffee Maker is brewing only a partial decanter, remember that some water is always absorbed by the coffee grounds and filter. Adjust the amount of water you input accordingly to compensate for this absorption.

      If your Bunn coffee is not staying hot, especially when using a STX model with a thermal carafe, pre-heating the carafe will help maintain the coffee's temperature for a longer time.
