Possible Causes

Cracked sump assembly, Loose or split drain hose, Leaking circulation pump seal, Loose clamp on inlet or drain connections

How to Fix / Troubleshooting

Safety First: Turn off power and water supply immediately to prevent further leakage and electrical hazards.

  • Remove toe-kick: Take off the lower front panel and inspect the base with a flashlight for signs of dripping or dried mineral trails.
  • Check hoses and clamps: Inspect the drain hose, inlet hose, and internal rubber hoses for cracks or loose clamps. Tighten clamps and replace damaged hoses.
  • Inspect sump and pump: Look for water around the sump seal and circulation pump. If the pump housing or sump is cracked or leaking at the seal, replace the sump and motor assembly.
  • Test after repair: Run a short cycle while observing underneath to confirm the leak is resolved.
