00620774 Dishwasher Pump Drain
The
00620774 is a genuine OEM Bosch
dishwasher dr
ain pump (often referenced as a BLDC drain pump on some platforms). Its job is to evacuate dirty water from the sump through the drain hose during drain phases and at the end of cycles. A failing drain pump can be electrically open/shorted, mechanically seized, or obstructed by debris (glass, labels, food, broken plastic). Symptoms: dishwasher won’t drain, standing water in tub, humming/buzzing during drain, intermittent draining, drain error codes, or water backing up due to a failed internal check valve or restriction.
IMPORTANT: Always check the drain path (filter, sump cover, check valve, drain hose loop/air gap, disposer knockout) before replacing the pump.
CRITICAL: Disconnect power at the breaker before servicing; water spill risk is high.
