KitchenAid KCM0812 coffee maker troubleshooting
KCM0812 is a siphon coffee maker manufactured by the Whirlpool-owned U.S. brand KitchenAid. Siphon coffee brewing, sometimes called “vacuum” brewing, is the key feature of this model. This technique involves using vapor pressure for making the water move from the carafe into an upper brewing reservoir.
| PROBLEM | SOLUTION |
|---|---|
| If the LED light is not illuminated: | Check to see whether the Siphon Coffee Brewer is plugged into a grounded 3-prong outlet. If it is, check the fuse or circuit breaker on the electrical circuit the Coffee Brewer is connected to and make sure the circuit is closed. |
| If water does not flow up into the brew unit from the carafe... | • Check water was added to carafe. • Check the On/Off switch is turned in the on position with LED illuminated. • Check the power cord is plugged in. • Check the brew unit is properly seated to the carafe and the brew unit handle aligns with the carafe handle. |
| If coffee grounds found in carafe... | • Check that the coffee filter is locked into place. |
| If coffee does not drop from the brew unit into the carafe... | • Check grind size. Maybe too fine which can clog the filter. • Check the brew unit is properly seated to the carafe and the brew unit handle aligns with the carafe handle. |
| If during brewing, coffee leaks out of the top of the brew unit... | • Be certain not to overfill the carafe. Make sure not to fill past the “8 cups/max” line. • Do not reboil a pot of previously brewed coffee. Reboiling the coffee can cause the brew unit to overflow. |
