De'Longhi Keypad Matrix / Contact Contamination

Buttons respond intermittently or register the wrong function when pressed.

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

Moisture or grease under keypad overlay, Worn membrane contacts, Partially loose ribbon cable, Faulty keypad scanning circuit on PCB

Safety first: Unplug the cooker before cleaning.

Surface cleaning: Wipe the keypad area with a cloth lightly dampened with mild detergent, then dry thoroughly.
Avoid sharp objects: Do not press buttons with fingernails or utensils; this can damage the membrane.
Power reset: Unplug for 10 minutes, then reconnect and test button response.

Persistent misreads indicate internal keypad or PCB issues that require professional replacement.
