Here’s a breakdown of common Electrolux dishwasher error codes:

Water Supply and Filling Issues

i10, i11, iF0, iF1: Water Fill Valve Error or Overfilling Detected

These codes generally indicate a problem with the dishwasher’s water supply or that the appliance has detected an overfill situation.

Possible Causes:

Closed water tap.
Low water pressure.
Kinked or blocked inlet hose.
Clogged inlet valve filter.
Faulty water inlet valve.
Drain hose positioned too low, causing siphoning.
Faulty pressure sensor or its hose is obstructed, bent, or leaking.
Faulty wiring to the inlet valve or pressure sensor.
Issues with the flow meter (if applicable to your model).
Leaking in the base of the appliance (for iF0, iF1).
Faulty main control board.

Troubleshooting Steps:

Check the Water Supply: Ensure the water tap supplying the dishwasher is fully open and that there is adequate water pressure. The recommended water pressure is typically between 40 and 80 psi. If your home’s water pressure is consistently low, a plumber may need to investigate.
Inspect the Inlet Hose: Examine the water inlet hose for any kinks, bends, or visible blockages. Ensure it’s securely connected to both the water source and the dishwasher.
Clean the Inlet Valve Filter: Locate the filter on the water inlet valve (where the hose connects to the dishwasher). Turn off the water supply, disconnect the hose, remove the filter, and rinse it clean under running water.
Check Drain Hose Position: The drain hose should be looped up higher than the dishwasher’s base (typically at least 40 cm or about 16 inches) before connecting to the drain. This prevents water from continuously draining out while the dishwasher is trying to fill.
Inspect for Leaks (iF0, iF1): If you suspect overfilling or a leak in the base, carefully inspect the hoses, connections, and the bottom tray of the dishwasher for any signs of water. A small amount of water in the base can trigger the flood switch.
Examine Wiring: Visually inspect the wiring harnesses connected to the water inlet valve and the pressure sensor for any signs of damage or loose connections.
Consider Component Testing (Advanced): If you’re comfortable using a multimeter, you can test the resistance of the water inlet valve solenoid. Typical values are around 0.9−1.1KΩ at 120V AC or 2.8−3.3KΩ at 220V AC.

Water Drainage Issues

i20: Water Drainage Error

This code indicates that the dishwasher is not draining water properly.

Possible Causes:

Clogged or kinked drain hose.
Blocked drain pump filter.
Obstruction in the drain pump or drainage system.
Drain hose connected too high (should be no more than 60 cm or about 24 inches above the appliance base).
Faulty drain pump.
Faulty pressure sensor.
Faulty wiring to the drain pump or pressure sensor.
Faulty main control board.

Troubleshooting Steps:

Check and Clear the Drain Pump Filter: This is the most common cause of drainage issues. Locate the filter at the bottom of the dishwasher tub, remove it according to your manual, and thoroughly clean it of food debris and buildup.
Inspect the Drain Hose: Ensure the drain hose is not kinked, bent, or blocked. Verify that its connection to the under-sink plumbing or garbage disposal is clear. If connected to a garbage disposal, ensure the knockout plug has been removed.
Check Drain Hose Height: Confirm the drain hose is not elevated more than 60 cm (approx. 24 inches) above the dishwasher’s base.
Inspect the Drain Pump Impeller: With the power off and the filter removed, you may be able to visually inspect the drain pump impeller for any large objects or debris obstructing its movement. Be cautious when doing this.
Examine Wiring: Check the wiring harness connecting the drain pump to the main control board for any damage or loose connections.
Consider Component Testing (Advanced): Using a multimeter, you can test the resistance of the drain pump motor. For a single-phase pump, expect values around 15−18Ω at 120V AC or 180−230Ω at 220V AC. For a BLDC (brushless DC) drain pump, the resistance between any two of the three terminals (U, V, W) should be approximately 90Ω.

Recommendation to Prevent Drain Problems: Regularly clean the drain pump filter and avoid overloading the dishwasher or using excessive detergent, as these can contribute to blockages.

Water Overflow and Leakage

i30, i36: Water Overflow Error
