    Why is no coffee coming out of my Bunn BX-B Coffee Maker?

      If coffee isn't coming out of your Bunn Coffee Maker, make sure the lid is closed. The reservoir may need to be refilled, as evaporation can occur over time. Ensure you've added the minimum water input, as the brewer requires at least 4 cups (591.5 ml / 20 oz) to begin brewing. Also, check the sprayhead holes and clean them if necessary.

    Why is my Bunn BX-B Coffee Maker brewing cold coffee?

      If your Bunn Coffee Maker is brewing 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 heat to the proper temperature. For BX, GRX, and NHBX models, the warmer switch should be in the 'on' position. If you're using a BTX model with a thermal carafe, pre-heating the carafe will help your coffee stay warm longer.

      To prevent your Bunn Coffee Maker funnel from overflowing, use BUNN paper filters. Check if the sprayhead is missing and replace it if necessary. The issue might be caused by using decaffeinated, fine grind coffee, or softened water.

    What to do if my Bunn Coffee Maker only brewed a partial decanter?

      Miranda NelsonAug 13, 2025
      If your Bunn Coffee Maker only brewed a partial decanter, the reservoir may need to be refilled due to evaporation over time. Also, some water is always absorbed by the coffee grounds and filter, so you may need to adjust the water input accordingly.

    Why is my Bunn BX-B Coffee Maker making a loud rumbling noise?

      Katelyn MoranSep 12, 2025
      If your Bunn Coffee Maker is making a loud rumbling noise, make sure the lid is fully open. The brewer is not designed to hold water in the upper tray for an extended period, so ensure proper use. Remove the top lid to ensure the rocker arm is snapped in place and the rubber stopper area is thoroughly cleaned.
