Dishwasher
E8
The E8 error code on an Electrolux dishwasher indicates a problem with the water level sensor or overfill detection — it’s a moderately serious fault that will stop your machine mid-cycle, but it’s often fixable at home without a callout.
What does this error mean?
The E8 code tells you that the dishwasher’s control board has detected an abnormal water level — typically too much water in the base or tub. The machine is designed to cut out at this point to prevent flooding. In most Electrolux models, this links directly to the pressure switch or float switch system that monitors how much water has entered the appliance.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the machine first: switch off at the mains, wait 5 minutes, then power back on and run a short cycle. A temporary sensor glitch may clear itself.
Remove and clean the filter: pull out the cylindrical filter and flat mesh filter from the bottom of the tub, rinse under hot water, and use a soft brush to clear grease or food debris. Refit and test.
Check and clear the drain hose: pull the machine out slightly, inspect the hose at the back for kinks or blockages. Disconnect it from the sink waste and blow through to confirm it’s clear.
Inspect the float switch: remove the bottom rack and look for a small dome-shaped plastic float near the front-left of the tub floor. Press it up and down — it should move freely. If it’s stuck or gummed up, clean around it with warm soapy water.
Check the base tray for standing water: carefully tilt the machine backwards about 45° (have towels ready) to drain any water that has pooled in the base tray. If water is present, this confirms a leak from an internal component — do not continue using the machine.
If none of the above resolves it, the pressure switch or water inlet valve likely needs replacing — these are straightforward parts to swap on most Electrolux models if you’re confident working with appliances unplugged. Order parts via the model number on the door frame.
📞 When to call a professional
Call a qualified appliance engineer if you find standing water in the base tray (indicating an internal leak), if the inlet valve or pressure switch needs replacing and you’re not comfortable working on appliances, or if the error returns immediately after a reset and filter clean. Tell the engineer: ‘My Electrolux dishwasher is showing an E8 error code — I suspect either the pressure switch, float switch, or water inlet valve.’
⚖️ Repair or replace?
A professional repair for an E8 fault — typically replacing the pressure switch or inlet valve — will cost £80–£150 including parts and labour in the UK. If your dishwasher is under 5 years old, repair is almost always worth it. Over 8 years old with recurring faults, replacing with a new mid-range machine (£350–£550) is likely better value long-term.
