Dishwasher Not Draining? 00642239 Drain Pump – Fix Standing Water Fast
If your dishwasher finishes a cycle but leaves standing water in the bottom of the tub, the drain pump has likely failed. In most Bosch, Thermador, Gaggenau, and Kenmore Elite dishwashers, this is caused by a failed drain pump assembly. When it fails, water cannot be evacuated from the tub, preventing cycle completion, causing odors, and rendering the dishwasher completely unusable. ⚡ Common failure point in Bosch-built dishwashers. Part 00642239 is the genuine OEM replacement that restores full drainage and normal cycle operation immediately.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Appliance powers on and runs normally
- ✔ Wash and rinse functions work correctly
- ✔ Water supply and inlet confirmed OK
- ✔ ONLY problem is water remaining in the tub after the drain cycle

While the dishwasher base is open, inspect the drain hose and sump filter for cracks or blockages — a damaged hose or clogged sump can cause the new pump to fail prematurely or produce the same drainage symptoms.
⚙️ Installation
Skill Level: Moderate — 45–60 minutes. Disconnect power and water supply before servicing. Remove the kickplate and lower access panel to reach the pump in the base of the unit. Disconnect the wiring harness and drain hose clamps, unscrew the mounting bracket, swap the pump assembly, and reconnect all connections before testing.

💡 Pro Tip
Before replacing the pump, remove and clean the sump filter — a severely clogged filter can mimic drain pump failure symptoms. If the filter is clear and water still won't drain, the pump motor has failed and this part is your fix. Replacing both the pump and cleaning the filter at the same time prevents a callback.
