Possible Causes
Leak into base tray activating float switch, Faulty waterproof system valve, Split inlet hose, Loose internal hose clamp
How to Fix / Troubleshooting
Safety first: Unplug the washer and close the water tap immediately.
- Check for leaks: Carefully pull the machine forward and inspect underneath for water in the base tray.
- Dry the base: If water is present, tilt the machine slightly (with help) and soak up water with towels. Do not tip excessively to avoid water entering electronics.
- Identify source: Remove side or front panel to inspect hoses, pump, and tub seal for drips while filling (power must be restored only when panels are safely in place).
- Repair leak: Tighten or replace leaking hoses or clamps. If the waterproof inlet valve or double-walled hose is leaking, replace the complete assembly.
Because leaks can damage electronics and floors, consider professional service.
