• Failure may cause poor cleaning, no spray action, or a silent/stalled wash cycle
• Humming, grinding, or buzzing from the pump area can indicate a failing motor
• May lead to unusually long or incomplete cycles due to low circulation

• Disconnect electrical power and shut off the water supply before servicing
• Access from the bottom; remove the toe panel and tilt/lay the unit back to reach the pump/motor
• Mark and unplug wiring, release clamps/fasteners, and install the new motor with seals aligned as originally positioned
• After reassembly, run a short cycle and check for leaks and proper spray action

Sump assembly collects and channels a washer's drained water into the drain pump to let the machine empty properly. Replacing a worn or cracked sump helps stop leaks and restores normal draining performance. What it does:

• Directs and funnels tub water to the drain pump so the washer can evacuate water.
• Prevents water from leaking under the washer when intact and properly sealed.
• Can cause poor or no draining, standing water in the tub, or drain/pump-related error codes when damaged.
• May produce unusual noises during the drain cycle if cracked or clogged.

• Disconnect power and turn off water supply before starting any repair.
• Access typically requires removing the washer's front or lower access panel; support the machine as needed.
• Inspect and replace any worn seals, hoses, or clamps when installing to ensure a watertight fit.
• After installation, run a short drain/spin cycle and check for leaks before returning the washer to regular use.
