GE Dishwasher Repair – Hartville, OH (CDT866P2M4S1)

A GE dishwasher in Hartville had a blank screen that prevented the homeowner from seeing what they were selecting. The dishwasher still worked, but the display was completely dead. When we opened up the control panel, we found extensive corrosion and burnt out spots on several resistors and small components.

The Problem

The screen on the dishwasher went blank, making it impossible to see what cycle or options were being selected. The dishwasher still functioned, but operating it was basically guesswork without the display feedback.

Diagnosis

The old user interface board was clearly bad, showing corrosion and burnt out spots on several of the resistors and small components. This is somewhat of a common issue with GE dishwashers. Fortunately, GE had already sent out a replacement board under warranty.

The Repair

• Parts replaced: WD21X24945 — configured UI control (customer-supplied under warranty)
• Work performed: Installed new user interface board
• Result: Display restored to full function

Is It Worth Repairing?

GE dishwashers from this era have known control board issues, but when the part is covered under warranty, it’s absolutely worth fixing. The dishwasher itself was still functioning mechanically, so replacing just the interface board restored it to full operation at minimal cost.

Maintenance Tips for GE Dishwashers

• Keep the control panel dry — moisture intrusion is a leading cause of board failures in GE models
• Don’t slam the door shut, as vibration can loosen connections to the display board
• Register your GE dishwasher for warranty coverage, as control boards are a common failure point
