Ge Dishwasher: door sensor malfunction

Professional Repair Guide

What is this symptom?

Experiencing a GE Dishwasher door sensor malfunction? Your appliance may not recognize the door as closed, preventing cycles from starting or triggering 'door open' errors. This issue often stems from a faulty door latch assembly or sensor switch, leading to communication failures with the control board. Troubleshoot effectively with our tips.

Urgency: Medium

Important Tips for Ge Models

  • GE dishwashers typically use a combined latch/switch assembly (part number examples WD01X29878) that must signal closure to the control board; failure of this assembly is a frequently reported cause of door closure errors.

Possible Causes

Faulty door latch assembly (door sensor switch failure)

How to Identify: Dishwasher won’t start, control board indicates door not closed even when it is; testing continuity with a multimeter shows open circuit on switch contacts when door is closed.

Part: Door latch assembly (e.g., GE part WD01X29878)

DIY Solutions

Inspect and Realign Door/Latch

Easy 10-20 minutes
Tools Needed: none or basic screwdriver

  2. Close the door slowly, feeling for smooth engagement of the latch; adjust the rack or reposition dishes if needed.
  3. Gently push/pull the door while closing to ensure the latch striker engages properly.
⚠️ Safety First: Ensure dishwasher is off before handling dishes/racks.
