The WG04F05477 is the genuine OEM left switch breakwater for GE dishwashers. This small but critical component sits in the door latch assembly and controls the left-side door switch operation, ensuring the dishwasher starts and stops correctly when the door is opened and closed. If your dishwasher won't start, runs with the door open, or has a faulty door latch response, this breakwater is a common culprit.

✓ Model-Specific Repair Pages

The WG04F05477 breakwater is part of the door latch and switch assembly on GE Profile dishwashers in the GLDT690 and GLDT696 series. It acts as a physical barrier and actuator that engages the left door switch when the door is latched, signalling the control board that it's safe to begin a wash cycle. This part directly supersedes the older WD21X10391.
