Bosch 00172272 Dishwasher Pump to Heater Hose Clamp

Dishwasher Pump to Heater Hose Clamp – Bosch

The dishwasher pump to heater hose clamp secures the hose connecting the wash pump to the heater assembly, keeping the connection tight and leak-free during operation. When the clamp corrodes, cracks, or loses tension, the hose can loosen and water may leak inside the dishwasher. This direct-replacement hose clamp restores a secure, watertight connection between the pump and heater hose.
