E13 error; machine detects water in base tray and may activate safety cut-out.

Safety first: Disconnect power and close the water supply immediately to prevent further leakage.

• Inspect base tray: Remove the front kick panel and check for water in the base tray. Mop up all water and dry the area thoroughly.
• Check visible hoses and clamps: Look for drips around the drain pump, wash pump, inlet valve, and hoses while briefly turning the water back on.
• Examine door seal: Inspect the door gasket for tears, deformation, or heavy soil. Clean or replace if damaged.
• Monitor for recurrence: After drying and reassembling, run a short cycle while observing the underside for leaks. If the leak source is not obvious, a technician should perform a pressure test.
