Electrolux Dishwasher i20 Error Code: Meaning, Causes and fixes

The i20 error code on an Electrolux dishwasher usually appears when there’s an issue with water drainage. This error code is essentially an abbreviation for “Drain Pump,” indicating that the dishwasher is encountering difficulties in expelling water during either the wash or rinse cycle.

To get a bit technical, the i20 error code pops up when the pressure sensor fails to reach its home level within the specified time limit of 90 seconds. This sensor plays a crucial role in monitoring the water level within the appliance, and when it doesn’t reset within the allotted time, it triggers the i20 error, signaling a problem with drainage.

Unveiling the Factors Behind the Electrolux Dishwasher i20 Error Code

Let’s break down each of these contributing factors to the i20 error code on your Electrolux dishwasher:

  • The drain hose is like the escape route for water from your dishwasher. It should be installed in a straight path and connected to the drain system at a height of no more than 60 cm (approximately 2 feet). If the hose is bent or if the connection point is too high, the water won’t drain properly.
  • Think of the drain hydraulic circuit as a network of pipes and filters that guides water out of your dishwasher. If this circuit becomes blocked or obstructed, it’s akin to having a clogged pipe in your plumbing at home. Water won’t be able to flow freely, causing drainage issues within the dishwasher.
  • The drain pump’s primary function is to expel water from the appliance. It needs electricity to operate, and this power comes through wiring connected to the main control board. If there’s a problem with this wiring, it’s like a break in the electrical connection, preventing the drain pump from doing its job.

  • The drain pump is a critical component of the drainage process. It physically pumps the water out of the appliance. If the drain pump itself is faulty, water won’t be removed as it should.
  • The pressure sensor is like the dishwasher’s water level monitor. If it’s not working properly, it won’t be able to accurately tell the dishwasher when it has finished draining the water.
  • The main board of your dishwasher coordinates its various functions. If it’s faulty, the appliance won’t receive the right instructions to complete its tasks, including drainage.

Solving the Electrolux Dishwasher i20 Error: Step-by-Step Troubleshooting and Repair

Remember to exercise caution and ensure the appliance is disconnected from power before attempting any troubleshooting or repairs.

  1. Straighten the drain hose and adjust its height.
  • Inspect the drain hose for any kinks or bends. Straighten it out if necessary.
  • Check the height of the drain hose connection; it should be no more than 60 cm (about 2 feet) above the floor or drain. Adjust it if it’s too high.
  • Reconnect everything securely.
  1. Clear Blocked Drain Hydraulic Circuit:
  • Turn off and unplug the appliance.
  • Examine the drain pipes, filter, and connections for any obstructions. Remove any debris or foreign objects.
  • Ensure that the drain path is clear and unobstructed.
  • Reassemble and reconnect everything.
  1. Check and repair faulty wiring.
  • Inspect the wiring connecting the drain pump to the main control board.
  • Look for loose connections or damaged wires.
  • If you encounter any issues, please address them by repairing or replacing the wiring as necessary.
  1. Test and replace a faulty drain pump.
  • Access the drain pump, typically situated at the dishwasher’s lowermost part.
  • To check the resistance of the drain pump, use a multimeter and set the dial to the “ohms” (Ω) setting.
  • Carefully touch the probes of the multimeter to the two terminals of the drain pump.
  • If the dishwasher has a 120-vac drain pump (single phase), the resistance should fall within the range of 15–18 Ω.
  • If the dishwasher has a 220 Vac Drain pump (single phase), the resistance should be within the range of 180–230 Ω.
  • For a BLAC drain pump (three-phase), the resistance between the U, V, and W terminals should be approximately 90 Ω.
  • If the resistance measurement is not within the specified range for your drain pump type, it indicates a faulty drain pump, and it should be replaced.

  1. Diagnose and replace a faulty pressure sensor.
  • Locate the pressure sensor, often positioned near the bottom of the dishwasher.
  • Inspect the sensor for any damage or loose connections.
  • If it’s found to be malfunctioning, replace it.
  1. Address issues with the Main Control Board:
  • First, disconnect the appliance from the power source.
  • Inspect the main control board for visible damage or burned components.
  • If there are signs of a faulty control board, it may need replacement.

Conclusion:

Tackling the Electrolux dishwasher i20 fault code is all about methodical troubleshooting. By following these steps, you can address the root causes and restore your dishwasher to its optimal working condition. Remember to prioritize safety.

Frequently Asked Questions (FAQs) about Electrolux dishwashers i20 error code:

The i20 error code on your Electrolux dishwasher indicates a problem with water drainage. It essentially stands for “Drain Pump Error,” signifying that the appliance is having difficulty draining water during a wash or rinse cycle.

To prevent the i20 error code, ensure that the drain hose is properly configured, straight, and connected at an appropriate height. Regularly check for any blockages in the drain hydraulic circuit, including screen filters, and keep it clear. Maintain the dishwasher’s components, including the drain pump and pressure sensor, in good working condition.

While you can try resetting the appliance by pressing the Cancel/Reset button for 3 seconds or turning the dishwasher off for 8 minutes and then back on, the i20 error code usually reappears if the underlying drainage problem is not resolved. It’s important to diagnose and address the root cause, as outlined in our blog post troubleshooting guide.
