Possible Causes
Loose or cracked sump hose, Leaking drain pump seal, Split internal recirculation hose, Corroded tub-to-pump connection
How to Fix / Troubleshooting
Safety first: Unplug the appliance and close the water tap. Water under the machine can be slippery and hazardous.
Step-by-step checks:
- 1. Pull out the machine: Carefully slide the washer-dryer out to access the rear and sides. Use a tray or towels to catch any dripping water.
- 2. Remove panels: Take off the rear (and if needed, front lower) panel to inspect hoses and pump while running a short fill or rinse cycle.
- 3. Identify leak source: Look for active drips from the sump hose, pump body, heater flange, or internal hoses. Water trails or limescale marks can indicate slow leaks.
- 4. Tighten or replace components: Tighten hose clamps, replace cracked hoses, or replace a leaking pump. Always use correct Neff/Bosch parts and new clamps where necessary.
When to call a technician: If the leak originates from the tub seam, bearing seal, or heat exchanger, professional repair is recommended.
