Description

This sump is the dishwasher wash-pump housing that collects and directs wash water to the pump assembly, keeping circulation and drainage working properly. Replacing a damaged sump restores proper water flow and helps prevent leaks. What it does

• Houses the wash pump and channels water between the tub and pump for normal wash and drain cycles.
• Prevents internal leaks by providing a sealed path for wash water.
• Symptoms it commonly addresses: leaking under the dishwasher, poor wash performance, pumps running but no water movement, or intermittent drainage problems.
• Works with the motor/pump assembly and associated seals to maintain correct water flow.

What's included One sump (wash pump housing) — ships as a single part. Install notes

• Disconnect power and shut off water supply before starting any repair.
• Access typically requires removing the lower kickplate and tilting or pulling the dishwasher out to reach the sump area.
• Inspect pump seals, mounting clips, and gaskets during replacement; replace any worn or damaged components separately.
