If coffee does not come out of the Bunn coffee maker, unplug the machine, place cold water into the decanter and put the empty funnel into the guides. Fill the brewer with the cold water from the decanter, and place the decanter on the base until the internal tank begins to fill. Repeat the filling process, and let the water flow through the funnel and into the decanter. Once it stops, empty the decanter, plug in the machine and attempt to brew coffee.

If the funnel overflows, check for lime buildup on the sprayhead, and clear it with a toothpick or scrubbing brush if it's present. This problem may also be fixed by using coarser ground coffee or using Bunn coffee filters. If water begins flowing while the lid is still open, ensure it is not partially closed or completely remove the lid to solve this problem.

A worn gasket can cause the coffee maker to leak. This happens over time. To fix the problem, appliance owners can check the condition of the gasket and seals and replace them if needed. Other causes for this problem include improper care or maintenance and mineral deposits accumulating in the coffee maker. Appliance owners should care for their appliances as described in the user manual.

Using the wrong filter can cause grounds in the coffee or cause the funnel to overflow. Appliance owners can replace the filter with one that is specifically designed for use with Bunn coffee makers. The spray-head should also be inspected and replaced if it is not working properly.

Finally, mineral deposit buildup can cause the coffee maker to make loud, rumbling noises. The problem can easily be fixed by cleaning the appliance regularly using a de-lining spring. Appliance owners should also avoid using soften water to prevent the problem from occurring. Using improperly stored coffee, varying mixes, brands and quantities, and using water with high sulfur content can cause coffee to taste bitter or weak.
