How to Fix Electrolux Dishwasher Error 20

Error Code: 20 Difficulty: Moderate

Problem: Indicates a drainage problem, which could be caused by a clogged filter, a blocked or kinked drain hose, or a faulty drain pump. This is an alternative display for the ‘i20’ error code.

How to Fix 20 Error (Step-by-Step)

1. Turn off the power to the dishwasher at your home’s circuit breaker to ensure safety.
2. Open the dishwasher door and remove the bottom dish rack to access the filter system.
3. Twist the cylindrical filter counter-clockwise and lift it out, along with the flat mesh screen underneath. Wash both parts thoroughly with warm, soapy water to remove any food debris.
4. While the filter is out, inspect the sump area at the bottom for any obstructions. Reinstall the clean filter and screen.
5. Locate the drain hose under your sink. Check the entire length of the hose for any visible kinks or bends that could restrict water flow and straighten them.
6. Disconnect the drain hose from the garbage disposal or sink drainpipe to check for clogs at the connection point. Clear any debris you find before reattaching the hose securely.
7. If the problem persists after these steps, the drain pump may be faulty and require replacement, which involves accessing the bottom of the appliance.
8. Turn the appliance off, wait about 2 minutes, then turn it back on.

Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
