Dishwasher Not Draining or Making Grinding Noise? Drain Pump 00631200 – Fix Drain Faults Fast

If your Bosch dishwasher has standing water in the tub after a cycle, is making a loud humming or grinding noise during drain, or is throwing E24 or E25 error codes, a failed drain pump is the most common cause. In most Bosch-built dishwashers, the drain pump is the sole component responsible for expelling wastewater from the tub — when its motor burns out or the impeller jams, water cannot exit and the dishwasher stalls or errors out. ⚡ Common failure point in Bosch SGE, SHE, SHX, SHEM, SHPM, and SHXM series dishwashers. Part 00631200 is the genuine OEM drain pump that restores full drain function — superseding 631200, 1208028, AP2802385, and PS3439123 with no modification required. An XPart premium aftermarket option (DW31200) is also available.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dishwasher powers on and wash cycle runs normally
• ✔ Drain hose and household drain line confirmed clear and unobstructed
• ✔ Filter assembly has been cleaned and is free of debris
• ✔ Control board and door latch confirmed functional
• ✔ ONLY problem is water remaining in tub, drain noise, or E24/E25 error codes

🔧 Common Symptoms

• Dishwasher won’t drain — standing water left in tub after cycle completes
• Loud humming, grinding, or buzzing noise during drain cycle
• E24 error code (drain blocked / pump failure)
• E25 error code (drain pump blocked or impeller jammed)
• Dishwasher stops mid-cycle during drain phase
• Water leaking under the dishwasher from pump housing

✔ If these symptoms match, this is the most likely failed component in the drain circuit.

✔ In most cases, replacing this drain pump restores full drain function and clears error codes immediately.

⚙️ Installation

Skill Level: MODERATE — 30–45 minutes. Disconnect power and water supply before beginning. Remove the lower spray arm, filter assembly, and pump cover to access the drain pump. Disconnect the wiring harness and drain hose from the old pump, remove the mounting hardware, and install the new 00631200 in the same position. Reconnect all connections, reassemble the filter and spray arm, and run a short drain cycle to verify operation before replacing the base panel. Confirm the impeller spins freely by hand before powering on — any resistance indicates debris still present in the sump.
