I20
Electrolux i20 on a dishwasher: not draining
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
Electrolux uses i20 when the dishwasher cannot remove water from the tub in time. Unplug it, clean the filters and sump, and check that the drain hose is not kinked and sits within the heights Electrolux gives.
Safety first
Stop and check this first
- Unplug the dishwasher before putting your hands in the sump: there is water close to electrical parts and the pump sits underneath.
Safe checks you can perform
- Filters and sump
- Drain hose
- Sink spigot and blanking plug

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Drain pump check
What they doWith the appliance disconnected, the technician inspects the drain pump and its connection and measures against Electrolux specification.
They must show youthe measurement or the removed part with the visible fault.
In writingwhat was checked, the result and the reference of any replaced part.
Drain test
What they doAfter the repair, the technician runs a programme and checks the tub is empty with no i20.
They must show youan empty tub at the end of the programme.
In writingthe test and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
- 1
Filters and sump
No special tools
Procedure
- Who:
- you.
- How:
- unplug the dishwasher, remove the lower basket, take out the filters as the manual shows and clean filters and sump.
- Result that matters:
- filters free of debris and a clear sump.
- If there was debris and the programme drains after cleaning:
- that was the cause.
- If they were clean:
- move on to the hose; the filter is ruled out.
- Evidence to keep:
- a photo of the filters before cleaning.

Drain hose
No special tools
Procedure
- Who:
- you, with a tape measure.
- How:
- without moving the appliance, look at the hose and measure its length and the height of the drain point.
- Result that matters:
- no longer than 400 cm and a drain point between 40 and 85 cm, with no kinks.
- If it was kinked or out of range and drains once corrected:
- it was the installation.
- If everything is within range:
- the hose is ruled out.
- Evidence to keep:
- both measurements and a photo of the hose run.

Sink spigot and blanking plug
No special tools
Procedure
- Who:
- you, if the appliance is new or was moved.
- How:
- open the siphon inlet where the hose connects, see whether the blanking plug is still there and remove it; also check the spigot is not clogged.
- Result that matters:
- a clear path from the dishwasher to the house drain.
- If the plug was still in and it drains once removed:
- it was the installation.
- If everything was clear and i20 returns:
- book a repair; the problem is inside the appliance.
- Evidence to keep:
- a photo of the open siphon.

What it means
For Electrolux, i20 is a drainage problem: the appliance does not empty the tub within the expected time. The Electrolux guide checks, in order, the sink spigot, the filters and sump, the drain hose installation (no longer than 400 cm, drain point between 40 and 85 cm high, not kinked or damaged) and, on a new or moved appliance, the blanking plug in the siphon. If none of that explains it, the code does not say whether the drain pump has failed: a technician measures it.
Warnings and stop conditions
- Loweditorial warning
Unplug the dishwasher before putting your hands in the sump: there is water close to electrical parts and the pump sits underneath.
Evidence: Dishwasher displays error code I20, C2, F2 or AL6, or beeps twice, not draining
Symptoms and causes
Probable causes · in order
- Blocked filters or sumpCommon
Food debris in the filter or sump slows draining. You see it when you take the filters out: if there is debris and it drains after cleaning, this was it.
Evidence: Dishwasher displays error code I20, C2, F2 or AL6, or beeps twice, not draining
- Drain hose installed wronglyPossible
Kinked, damaged, longer than 400 cm or with the drain point outside 40 to 85 cm. You check it by looking at and measuring the hose, without opening the appliance.
Evidence: Dishwasher displays error code I20, C2, F2 or AL6, or beeps twice, not draining
- Siphon blanking plug not removedPossible
Only on a dishwasher just installed or moved. The siphon comes sealed with a plug that has to be removed so the water can leave.
Evidence: Dishwasher displays error code I20, C2, F2 or AL6, or beeps twice, not draining
