How to Fix / Troubleshooting
Safety first: Unplug the dishwasher and close the water tap immediately. Water in the base can reach live components.
- Pull out appliance: Carefully slide the dishwasher out of the cabinet to inspect the sides and rear.
- Check hoses and clamps: Remove side panels and base cover. Look for water tracks or mineral deposits around hoses and clamps. Tighten any loose clamps.
- Inspect sump and tub: Check the plastic sump and lower tub area for cracks or damage.
- Test after drying: Dry the base thoroughly, then run a short cycle while observing for new leaks.
- Replace damaged parts: Any cracked hose, sump, or tub component must be replaced. This is often a job for a professional technician.
