Smeg Dishwasher E1 Error Code

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 Smeg dishwasher E1 error code:

1. Turn off the dishwasher and unplug it. Safety first!
2. Check for leaks: Visually inspect the dishwasher for any signs of water leaks. Look under the appliance, around the hoses, and inside the tub.
3. 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.
4. Reposition the float switch: Consult your dishwasher’s manual for proper float switch placement. Make sure it moves freely.
5. 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.
6. 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.
