What the E8 error means
The E8 error code indicates that your Hoover dishwasher has detected water in the base pan beneath the inner tub. This triggers the anti-flood protection system, which stops the dishwasher from operating to prevent flooding your kitchen. The water in the base pan is detected by a float switch or sensor, which sends a signal to the control board to display the E8 error and halt the cycle.
Common causes
- Leaking door seal or gasket allowing water to escape during the wash cycle
- Blocked or damaged drain hose causing water to back up and overflow
- Faulty water inlet valve allowing excessive water into the machine
- Damaged internal hoses or loose connections leaking water into the base
- Clogged sump or filter causing water to overflow from the wash chamber
- Faulty float switch giving false readings even when no leak is present
How to fix the E8 error
- Turn off and inspect for visible leaks Switch off the dishwasher at the mains and pull it away from the wall if possible. Check around the door seal, underneath the unit, and around the supply and drain connections for any signs of water. Mop up any standing water.
- Remove water from the base pan Tilt the dishwasher backwards slightly (about 30 degrees) for 10-15 seconds to drain water from the base pan into a towel placed underneath. Alternatively, remove the lower access panel and use towels to soak up water from the base. This will reset the float switch.
- Check the door seal Inspect the rubber door gasket for cracks, tears, or debris that might prevent a proper seal. Clean the seal thoroughly with warm soapy water and check for any damage. Replace the gasket if it appears worn or damaged.
- Inspect internal hoses and connections Remove the lower spray arm and filter assembly to access the sump area. Check all visible hoses, clamps, and connections for tightness and damage. Tighten any loose clamps and replace damaged hoses.
- Clean the filter and check for blockages Remove and thoroughly clean the filter assembly, checking for food debris or foreign objects. Inspect the drain pump area for blockages that could cause water to back up and overflow.
- Test the float switch Locate the polystyrene float in the base pan (usually accessible by removing the kick plate). Ensure it moves freely and is not stuck in the raised position. If it is stuck or damaged, it may need replacement.
