GE Dishwasher: door sensor issue

Professional Repair Guide

What is this symptom?

If your GE dishwasher is showing that the door is open or won't start, it may be a door sensor issue. This could be due to a faulty latch, misalignment, or obstructions that prevent the door from closing properly. Addressing this issue promptly can help restore functionality and ensure your appliance operates efficiently.

Urgency: Medium

Important Tips for GE Models

GE dishwashers use a latch and door switch to detect closed door; misalignment or latch failure often triggers false open detection preventing start.

How to Identify: Dishwasher won’t start; pressing door firmly may allow start; visual misalignment or broken latch parts.

Part: Door latch assembly / latch strike

Defective door switch not detecting closed door

How to Identify: Error persists after latch inspection; multimeter continuity test fails when door closed.

Part: Door switch inside latch assembly

Obstruction or misloaded racks preventing door closure

How to Identify: Items sticking out or racks not fully pushed in, preventing full door closure.

Part: Dish racks / obstruction

Door alignment issues including hinge or leveling causing poor latch engagement

How to Identify: Door appears crooked, rubs cabinet or does not sit evenly with the frame.

Part: Door hinges / leveling legs
