Possible Causes

Loose hose clamp on pump or drain, Cracked sump or tank weld, Seal failure on wash pump, Leaking fill or rinse line fitting

How to Fix / Troubleshooting

Safety first: Disconnect power and water supply. Do not work in standing water.

  • Remove access panels: Take off the lower front and side panels to inspect the base while the machine is filled (use caution if testing with power).
  • Identify leak source: Look for drips around the wash pump, drain pump, sump, and all hose connections. Use a flashlight and mirror if needed.
  • Tighten fittings: Gently tighten hose clamps and threaded fittings that show signs of seepage. Do not overtighten plastic fittings.
  • Replace seals or components: If the pump seal is leaking or the sump is cracked, the affected component must be replaced. This is typically a technician-level repair.
  • Dry base and retest: After repairs, dry the base completely and run a test cycle to confirm no further leaks.
