The E1 error code indicates a possible leak in your Smeg dishwasher. This triggers a safety feature that stops the dishwasher and prevents flooding.
Understanding the Cause
The dishwasher has a flood prevention system with a float switch. When the switch detects water in the bottom tray and stays stuck in the “closed” position for more than 5 seconds, the E1 error appears.
What causes the Smeg dishwasher E1 error code?
- Actual water leak: Leaking water from the tub, hoses (including the aqua-stop hose), components at the bottom (pumps, softener), or the connection hose can cause the float switch to activate.
- Float switch malfunction: The float switch itself might be faulty or improperly positioned, causing it to stay stuck in the “closed” position even without excess water.
- Electrical issue: Faulty wiring or a malfunctioning timer board could also be to blame.
How to fix the the Smeg dishwasher E1 error code:
- Turn off the dishwasher and unplug it. Safety first!
- Check for leaks: Visually inspect the dishwasher for any signs of water leaks. Look under the appliance, around the hoses, and inside the tub.
- Empty any water: If there’s water in the dishwasher’s base, carefully remove it with a towel or cup. This will help reset the float switch.
- Reposition the float switch: Consult your dishwasher’s manual for proper float switch placement. Make sure it moves freely.
- Check electrical connections: If you’re comfortable with electrical work, you can use a multimeter to check the continuity of the connections to the float switch and timer board. Refer to your dishwasher’s manual for the wiring diagram. If you’re unsure, consult a qualified appliance repair technician.
- Run a test cycle: Once you’ve addressed potential causes, restart the dishwasher and run a short cycle. If the E1 error reappears, the timer board might be faulty.
By following these steps, you should be able to identify and fix the cause of the E1 error code in your Smeg dishwasher.
