Possible Causes

Split sump hose, Loose hose clamp on pump or tub, Leaking heater seal, Cracked outer tub

How to Fix / Troubleshooting

Safety first: Unplug the appliance and turn off the water supply. Be prepared for water spillage when removing panels.

Step-by-step checks:

  • 1. Visual inspection: Remove the rear panel and run a short fill cycle while observing (keep clear of moving parts). Identify the source of the leak.
  • 2. Check sump hose: Inspect the large black hose from the bottom of the tub to the pump for splits or rubbing damage. Replace if perished and secure with new clamps.
  • 3. Tighten clamps: Check all hose clamps on the pump, tub, and dispenser connections. Tighten or replace as needed.
  • 4. Heater seal: Inspect around the wash heater where it enters the tub. If water seeps from this area, remove the heater, clean the seat, and refit with a new seal or replace the heater assembly.
  • 5. Cracked tub: If the plastic outer tub is cracked, it may require replacement of the entire tub assembly, which is a major repair.
