Customer Questions and Answers for Sump And Motor Assembly (Dishwasher) by Whirlpool

This sump and motor assembly replaces the lower tub sump with the circulation pump pre-installed. It restores proper water recirculation to the spray arms and a tight seal at the tub floor to help reduce leaks and noise.

• Circulates wash water through the spray arms for consistent cleaning performance
• Channels and filters water beneath the tub via the integrated sump
• Maintains a watertight seal at the tub base
• Common symptoms of failure: weak or no spray action, poor cleaning results, loud humming/grinding during wash, or water leaking from the center bottom area

• Disconnect power and turn off the water supply before servicing; allow internal components to cool
• Remove the lower rack, spray arm, and filters to access the sump; disconnect hoses and wiring, then release the locking tabs to remove the assembly
• Ensure all seals/O-rings are properly seated; fully engage hose and electrical connections to prevent leaks
• After installation, run a brief test cycle and inspect carefully for leaks before reassembling panels
