Answer to continue safely
Is it safe to keep using?
No. The dishwasher cannot complete a wash cycle while i20 is active. Standing water in the tub can cause odors and potential mold growth. Resolve the drainage issue before running the machine again.
Can I reset the code?
Yes. You can reset i20 by pressing Start/Cancel for 3 seconds or by turning off the dishwasher at the breaker for 60 seconds. However, if the drain blockage is not cleared, the code will return immediately when the next drain cycle is attempted.
When to stop immediately?
Stop if you notice: The drain pump makes no sound at all when a cycle is started, Water is leaking from beneath the dishwasher onto the floor.
Symptoms You May Notice
Standing water remains in the tub after a cycle
The dishwasher completes or pauses mid-cycle, but several centimeters of water remain pooled at the bottom of the tub because the drain cycle did not clear the sump.
Drain pump runs but water does not exit
You can hear the drain pump humming, but water is not moving through the drain hose to the sink plumbing, indicating a blockage downstream of the pump.
Error code i20 displays after starting a wash cycle
The machine begins the cycle, attempts an initial drain, and immediately triggers i20 because it detects residual water that cannot be pumped out.
Unpleasant odor from stagnant water
Water that sits in the sump for hours or days begins to produce a sour or musty smell, especially noticeable when the door is opened.
Possible Causes
Clogged drain filter
Food particles, glass fragments, or grease have accumulated in the cylindrical drain filter or the fine mesh screen beneath it, blocking water flow to the pump.
DIY PossibleKinked or blocked drain hose
The drain hose between the dishwasher and the sink drain or garbage disposal is kinked, compressed, or internally clogged with grease buildup.
DIY PossibleFailed drain pump motor
The drain pump impeller is jammed by debris or the motor windings have failed, preventing the pump from generating enough pressure to expel water through the hose.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the drain filter
Remove the bottom dish rack. Twist and lift out the cylindrical drain filter from the sump floor. Rinse it under warm running water with a soft brush. Also clear any debris visible in the filter housing before reinstalling.
Check beneath the fine mesh screen as well — small glass shards or seeds often hide underneath.

2
Inspect the drain hose
Pull the dishwasher forward enough to access the drain hose at the rear. Trace it from the dishwasher connection to the sink or disposal inlet. Straighten any kinks and disconnect the hose end to blow through it and confirm airflow.
If the hose connects to a garbage disposal, run the disposal first to clear any food that may be blocking the shared drain port.

3
Reset and test
Press and hold the Start/Cancel button for 3 seconds to cancel the current cycle. Close the door and select a quick rinse cycle. Listen for the drain pump to activate within the first 30 seconds and verify water is leaving the tub.
On some Electrolux models, pressing the Start button twice quickly initiates a drain-only cycle.
When to Call a Professional
Contact a qualified technician if:
- Drain pump motor hums but the impeller does not spin, indicating a seized pump
- A burning smell comes from the drain pump area during operation
- The control board shows additional error codes alongside i20, suggesting an electrical fault
