This Part Fixes These Problems

Washer Won't Drain

Water remains standing in the drum after the cycle ends; washer stops mid-cycle at drain phase.

E13 / E04 Error Code

Control board displays drainage fault codes E13 or E04, preventing cycle completion.

Loud Pump Noise / Humming

Pump hums, buzzes, or grinds loudly during the drain phase but fails to move water; motor may be seized or impeller stripped.

Washer Leaking at Base

Water drips or pools beneath the front of the washer due to a cracked pump housing or failed pump seals.

Abnormal Vibration During Drain

Washer shakes excessively during drain phase caused by an imbalanced or damaged pump impeller assembly.

Product Description

Why Choose Our 436440 Washer Drain Pump Motor Assembly?

🔧
Built to OEM SpecificationsEngineered to match original Bosch specs: 120V / 60Hz / 1.25A motor, rated for 10-min ON / 50-min OFF duty cycle. Dimensions: 9-7/8"L × 5-1/8"W × 6-1/8"H — a precise drop-in fit with no modifications required.
⚙️
Complete Assembly IncludedComes pre-assembled with drain pump motor, impeller, ABS pump housing, cleanout filter screen, manual drain hose, hose clamp, and rubber mounting feet — everything needed for a full replacement right out of the box.
🔇
Quieter Than OriginalUpdated pump design uses precision-balanced impeller and vibration-dampening rubber feet to significantly reduce operational noise — many customers report the replacement runs quieter than the factory pump it replaced.
🛡️
Corrosion-Resistant ABS HousingUpdated white ABS volute housing replaces the older black-housing design. High-strength plastic construction resists corrosion, heat, and detergent chemicals — built to outlast original under heavy laundry loads.
🔌
Plug-and-Play Wiring ConnectorPrecision-molded wire harness connector matches the original Bosch plug exactly. No splicing, no adapters — stable electrical connection prevents loose contacts, intermittent faults, or error codes after installation.
🌐
Broad Cross-Brand CompatibilityFits Bosch WFMB / WFMC / WFVC / WFXD series front-load washers plus select Thermador and Gaggenau models. Replaces over 14 cross-reference part numbers including 00674704, 00703146, LP6440, AP3764202, PS3464593, EAP3464593, PS8714879, and 1106007.

💡 Pro Tip: How to Know Your Drain Pump Has Failed

Your part is likely the culprit if you notice any of the following:

⚠️ Washer displays E13 or E04 error code and stops mid-cycle

⚠️ Drum fills with water but will not drain — standing water remains after cycle

⚠️ Pump hums loudly or makes grinding noise during drain phase but no water exits

⚠️ Pump housing is hot to the touch after a drain attempt, indicating motor seizure

⚠️ Visible water leak from the pump area at the base of the washer

Before replacing, always clean the pump filter and check for obstructions (coins, bra underwires, socks). If the filter is clear and the E13/E04 code or no-drain condition persists, the pump motor or impeller is almost certainly the cause. The impeller is not available separately — replacing the complete assembly is the correct repair.

Questions & Answers

Will this pump fit my Bosch WFMC3200UC washer?
Answered by Support Team  ·  Mar 15, 2024
Yes. Part 436440 (00436440) is the correct drain pump assembly for the WFMC3200UC. It is confirmed compatible across the full WFMC3200UC variant lineup. Always verify by checking the part number on your existing pump before ordering.
My new pump came with a white housing but my original was black. Is this correct?
Answered by Support Team  ·  Nov 20, 2023
Yes, this is expected. Bosch updated the pump housing from black to white in a design revision. The new white housing is the current replacement for all older black-housing units. It is fully compatible and is a direct upgrade — no modifications needed.
The new pump came with a manual drain hose attached. Do I remove it?
Answered by Support Team  ·  Jan 8, 2025
No — do not remove the manual drain hose, hose clamp, or plug from the pump. Due to a housing design change, current replacement pumps include this hose to prevent leaking from the now-open port. The hose must be stowed near the pump inside the machine after installation.
My washer shows an E13 error code. Is the drain pump definitely the problem?
Answered by Support Team  ·  Jul 22, 2024
E13 typically indicates a drain fault. First, check and clean the pump filter (accessible via the front access door) for debris like coins or underwires. If the filter is clear and the washer still won't drain or the pump hums without moving water — especially if the pump body is hot to the touch — the pump motor or impeller has failed and this part is the correct fix.
Is this pump also compatible with Thermador and Gaggenau front-load washers?
Answered by Support Team  ·  Feb 10, 2026
Yes. The 436440 drain pump is a cross-brand part used in select Bosch, Thermador, and Gaggenau front-load washing machines. The same motor assembly (120V / 60Hz / 1.25A) was used across all three brands during the Nexxt and related series production runs. Confirm by matching your existing pump's part number to the replaces list: 00436440, 00674704, 00703146, LP6440, AP3764202, PS3464593, PS8714879, or 1106007.
