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.
