Keep-warm function does not work; coffee cools quickly after brewing.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed warming plate element, Open thermal fuse on plate, Faulty keep-warm thermostat, Defective control relay

Safety first: Unplug and allow the unit to cool before touching the plate.

Check settings: Ensure the keep-warm function is enabled and not set to zero minutes.
Feel for warmth: After brewing, carefully feel near (not directly on) the plate to see if it warms at all. If completely cold, the element or fuse may be open.
Avoid overloading: Do not place heavy or non-standard containers on the plate.
Service plate: Replacing the warming plate element or thermal fuse requires opening the base and should be done by a technician.
