Bosch Dishwasher E24 Error: Drain Fix & Pump Part Numbers (#00631200)
Quick Answer: The E24 error code on a Bosch dishwasher indicates a draining problem: residual water is not being pumped out of the tub within the required time limit. It is caused by a missing white pump cover inside the sump, a clogged drain hose at the sink air gap, or a failing drain pump (#00631200).
⚠️ Stop Before Buying a Pump: Over 40% of Bosch E24 errors happen right after someone cleans the filter and forgets to snap the small white plastic pump cover (#00611322) back until it clicks! Without that cover, the pump impeller simply spins water in circles.

- Scoop out standing water with a cup and pry off the small white plastic impeller cover at the bottom of the sump.

Frequently Asked Questions (Bosch E24)
Why am I getting Bosch E24 right after installing a new garbage disposal?
Your installer forgot to knock out the plastic drain plug inside the garbage disposal inlet nipple. Knocking out that plastic plug with a screwdriver and hammer solves E24 immediately at zero cost.
How do I replace the drain pump (#00631200) on a Bosch dishwasher?
Unplug the unit, remove the front kickplate (2 screws), unclip the wiring harness from the pump at the front center of the sump, press the locking tab, and twist the pump counter-clockwise a quarter turn to pull it straight out.
