Product Overview
Replace your faulty dishwasher flood switch and restore your appliance's heating and drying performance with the iFJF WD21X10519 Flood Switch. Designed as a direct OEM-compatible replacement for GE dishwasher models, this flood switch detects excess water in the base pan and prevents flooding — while also enabling the heating element and drying cycle to function properly. If your GE dishwasher isn't heating or drying dishes, a failed flood switch is often the culprit.

Why Replace Your Flood Switch?
A failed flood switch is one of the most common causes of GE dishwashers not heating or drying. When the switch malfunctions, it either falsely detects a leak (triggering constant draining) or fails to detect one (risk of flooding). Replacing it restores proper operation and protects your kitchen from water damage.
