• Check if coffee maker is plugged in, and if Tank Power Switch is ON. If the coffee maker
was not ON, wait 15 minutes for tank to reach operating temperature.
• Tank may not have reached operating temperature before brewing. The tank will reach
operating temperture 15 minutes after the coffee maker has been turned ON, or after a
brew cycle.
• This is normal if it occurs after a brew, or intermittently throughout the day. This occurs
as the water in the tank reheats.
• This sound may indicate that there is lime build-up on the heater. Clean the unit as
directed in the ROUTINE CLEANING section of the manual.
• Make sure lid is completely open to activate the rubber stopper in the pour-in bowl.
• The coffee maker is not deisgned to hold water in the pour-in bowl overnight.
• Remove the top cover to ensure that the rubber stopper is in palce and the area is clean.
• Are you using BUNN filters? Other filters may be the wrong size or porosity. You can
order more BUNN filters at bunn.com.
• Check to see if sprayhead is in place. If sprayhead is missing, the funnel will overflow
• If you brew decaf, use fine ground coffee, or have soft water, you may require use of a
special flow restrictor sprayhead. One can be obtained by completing an online form
at www.bunn.com/home-products/parts-form or by calling 1-800-352-2866 (USA) or
1-800-263-2256 (Canada).
