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)
- Turn off the power to the dishwasher at your home’s circuit breaker to ensure safety.
- Open the dishwasher door and remove the bottom dish rack to access the filter system.
- 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.
- While the filter is out, inspect the sump area at the bottom for any obstructions. Reinstall the clean filter and screen.
- 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.
- 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.
- If the problem persists after these steps, the drain pump may be faulty and require replacement, which involves accessing the bottom of the appliance.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Electrolux Dishwasher
Focused repair path: dishwasher fill, drain, wash, heat, latch, sensor, and control checks. Do not treat the fault as reset-only if it keeps returning; use the failed function to choose the next test.
- Disconnect power before opening panels, then confirm whether the Electrolux dishwasher repeats the same code after a clean reset.
- Match the symptom to the part of the cycle or function that fails: fill, drain, heat, cool, spin, latch, ignite, fan, sensor, or control response.
- Inspect simple causes first: airflow, water supply, drain path, door closure, filter, venting, wiring connectors, and visible damage.
- Use meter testing or service diagnostics before replacing electronic controls, because wiring, switches, sensors, and loads can mimic board failure.
- Use the complete Electrolux dishwasher model number from the appliance tag before ordering any model-specific part.
Check, inspect, clean, test, measure, remove, reconnect, clear, and replace parts only when the symptom supports that path. If these checks point toward a part, verify the complete Electrolux model number from the appliance tag before ordering.
