A Comprehensive Guide to Electrolux Dishwasher Error Codes

Knowing what to do when an error code pops up on your Electrolux dishwasher can be tricky. It’s tough to pinpoint the exact problem and figure out a fix without a guide.

That’s why we’ve put together a complete list of Electrolux dishwasher error codes, explaining what they mean and offering solutions to help you troubleshoot and resolve any issues.

Electrolux Dishwasher Error Codes Explained

Before you start any repairs, always unplug your dishwasher and use caution.

i10: Water Fill Valve Error

This code indicates a problem with the dishwasher filling with water.

Possible Causes:

• Closed water tap: The water supply to the dishwasher is off.
• Low water pressure: Insufficient water pressure from your home’s supply.
• Clogged or faulty inlet valve: The valve that controls water entry is blocked or not working correctly.
• Faulty inlet valve wiring: Damaged or loose wires connected to the inlet valve.
• Improper drain hose height: The drain hose is positioned too low (lower than 40cm above the appliance base), which can cause siphoning issues.
• Pressure sensor issues: A faulty pressure sensor, or its hose is obstructed, bent, or leaking, or the wiring is faulty.
• Faulty main PCB: The main control board is malfunctioning.

Solutions:

• Open the water tap. Ensure the water supply is fully on.
• Check water pressure. It should be between 40 and 80 psi. If it’s too low, you might need to call a plumber.
• Clean the inlet valve filter. This filter is usually on the inlet valve. Remove and rinse it with clean water.
• Inspect inlet valve wiring. Disconnect the wiring and check for any damage. Repair or replace if necessary.
• Test the inlet valve resistance. Use an ohmmeter to check the valve’s resistance. If it’s infinite, replace the valve.
  • Inlet Valve Ohmic Value:
    • 0.9 – 1.1 KΩ @ 120 Vac
    • 2.8 – 3.3 KΩ @ 220 Vac
• Examine the pressure sensor’s hydraulic circuit. Disconnect and check for leaks. Repair or replace if found.
• Check pressure sensor wiring. Disconnect the wiring and look for damage. Repair or replace if necessary.
• Consider replacing the main board if the error persists after trying the above solutions.

i20: Water Drainage Error

This means your dishwasher isn’t draining water properly.

Possible Causes:

• Improper drain hose setup: The drain hose is bent, kinked, or connected too high (above 60 cm), preventing proper drainage.
• Blocked drain hydraulic circuit: The internal pipes for drainage are clogged.
• Faulty drain pump wiring: Damaged wiring preventing the drain pump from operating.
• Faulty drain pump: The pump itself is not working.
• Faulty pressure sensor: The sensor that detects water levels isn’t functioning, so the dishwasher doesn’t know when to drain.
• Faulty main PCB: The main control board is malfunctioning.

Solutions:

• Clean the drain pump filter. Located at the bottom of the dishwasher, this filter collects food debris. Remove and rinse it thoroughly.
• Check drain pump wiring. Look for breaks or frayed wires between the main board and the drain pump. Repair or replace any damaged wiring.
• Test the drain pump resistance. Use a multimeter to check the pump’s resistance. If it’s outside the specified range, replace the pump.
  • Drain Pump Ohmic Value:
    • Single-phase: 15–18 Ω @ 120 Vac | 180–230 Ω @ 220 Vac
    • BLDC (three-phase): ~ 90 Ω between U, V, and W
• Check the pressure sensor. Ensure it’s functioning correctly.

• Faulty float microswitch: The switch activated by the float sensor is not working.
• Drainage problem: An underlying issue preventing water from draining (refer to i20).
• Faulty main PCB: The main control board is malfunctioning.

Solutions:

• Clean the drain pump filter. Ensure it’s free of debris.
• Inspect water tank and hoses. Check for blockages, leaks, or cracks in the water tank and connecting hoses. Tighten connections or replace hoses if you see drips.
• Check float wiring harness connection. Ensure it’s secure.
