Q: My Bunn coffee maker is not turning on. What could be the problem?
If your Bunn coffee maker is not turning on, the first thing to check is the power cord and outlet. Ensure that the power cord is properly plugged into both the coffee maker and the electrical outlet. Also, verify that the outlet is working by plugging in another appliance. If the issue persists, it’s possible that the thermal fuse or the on/off switch might be faulty. In this case, you may need to consult a professional for assistance or contact Bunn’s customer support.
Another possible cause could be a tripped circuit breaker or a blown fuse. Check your home’s circuit breaker or fuse box to see if the breaker has tripped or a fuse has blown. If so, reset the breaker or replace the fuse. If none of these solutions work, it’s likely that there’s an internal issue with the coffee maker, and you may need to consider replacing it.
Q: Why is my Bunn coffee maker leaking water?
A leaking Bunn coffee maker can be frustrating and messy. The most common cause of leaks is a clogged or dirty water reservoir. Check the reservoir for any blockages or mineral buildup and clean it thoroughly. Also, ensure that the reservoir is properly aligned and seated. If the leak persists, it’s possible that the gasket or seal around the reservoir might be worn out or damaged. Inspect the gasket and replace it if necessary.
Another possible cause of leaks could be a faulty or clogged brew head or spray head. Check these components for any blockages or mineral buildup and clean them thoroughly. If the leak is coming from the bottom of the coffee maker, it’s possible that the drain valve might be clogged. Check the drain valve and clean it if necessary. If none of these solutions work, it’s likely that there’s a more serious internal issue, and you may need to consult a professional for assistance.
Q: How do I descale my Bunn coffee maker?
Descaling your Bunn coffee maker is an essential maintenance task to remove mineral deposits and prevent damage. To descale your coffee maker, you’ll need a descaling solution specifically designed for coffee makers. Mix the solution with water according to the manufacturer’s instructions and pour it into the water reservoir. Run a brewing cycle to allow the solution to flow through the coffee maker. Repeat the process until the solution is gone.
After descaling, run several brewing cycles with just water to rinse the coffee maker thoroughly. It’s recommended to descale your Bunn coffee maker every 3-6 months, depending on usage and water quality. You can also use a mixture of equal parts water and white vinegar as a descaling solution. However, be sure to rinse the coffee maker thoroughly after using vinegar to prevent any residual taste.

Q: Can I use a paper filter in my Bunn coffee maker?
Yes, you can use a paper filter in your Bunn coffee maker, but it’s not recommended. Bunn coffee makers are designed to use a metal filter, which allows for a cleaner and more flavorful brew. Paper filters can absorb some of the coffee’s natural oils and flavors, resulting in a less flavorful cup. However, if you prefer to use a paper filter, make sure to use a high-quality filter specifically designed for coffee makers.
When using a paper filter, ensure that it’s properly seated in the filter basket and that the basket is securely in place. Also, be aware that paper filters can clog the coffee maker’s brew head or spray head, so be sure to clean these components regularly. If you’re unsure about using a paper filter or have any concerns, consult your Bunn coffee maker’s user manual or contact Bunn’s customer support.
Q: How do I clean my Bunn coffee maker’s brew head and spray head?
Cleaning your Bunn coffee maker’s brew head and spray head is essential to prevent clogs and ensure optimal performance.

Repeat the process until the solution is gone.
After cleaning, run several brewing cycles with just water to rinse the coffee maker thoroughly. You can also use a cleaning brush or a small toothbrush to gently scrub away any mineral buildup or debris from the brew head and spray head. Be sure to rinse the components thoroughly after cleaning to prevent any residual taste. It’s recommended to clean the brew head and spray head every 1-3 months, depending on usage and water quality.
