E8 displayed; poor washing performance and unusual water levels

Safety first: Unplug the dishwasher and turn off the water supply. Be prepared for residual water when removing hoses.

• Listen during cycle: If the dishwasher fills but you do not hear the usual strong spray noise, the circulation pump may not be running.
• Check for obstructions: Remove filters and inspect the sump for broken glass, bones, or plastic that could jam the impeller.
• Access pump: Lay the dishwasher on its back (with towels) and remove the base panel. Locate the circulation pump attached to the sump.
• Inspect wiring and connectors: Ensure the pump connector is secure and there are no burnt marks or melted plastic.
• Manual impeller check: If accessible, try to rotate the impeller gently with a screwdriver. If seized or very stiff, the pump must be replaced.
• Replace pump assembly: Order the correct Rosières circulation pump and install, ensuring all seals and clamps are correctly fitted to prevent leaks.
