Bosch 00165262 Dishwasher Drain Check Valve

Dishwasher Drain Check Valve – Bosch

The dishwasher drain check valve is a one-way valve in the drain system that allows water to flow out to the drain but prevents it from flowing back into the dishwasher tub after draining. When the check valve fails or sticks open, water from the drain line can siphon back into the tub, leaving standing water after a cycle. This direct-replacement drain check valve restores proper one-way drainage and prevents backflow.
