Zanussi E20 on a washing machine: not draining in the expected time
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On a Zanussi washing machine, E20 means it cannot drain within the expected time. Check the drain hose goes no more than 10 cm into the drain, is not kinked, and clean the pump filter.
Safety first
Stop and check this first
- Unplug the washer before opening the filter and use a container: water will reach the floor next to an electrical appliance. If the programme was hot, let it cool.
Safe checks you can perform
- Hose position and height
- Filter and pump
- Drain test into a bowl
Leave these tasks to a qualified professional

- Do not attempt this professional task: Drain test after the repair
What a technician must be able to justify
Technician visit
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 diagnosis
What they doWith the washer unpowered, the technician checks whether the pump turns freely, measures its winding with a multimeter and checks the internal duct.
They must show youthe measured pump value against the Zanussi specification or the object that blocked it.
In writingcheck, result, any replaced part with reference and why.
Drain test after the repair
What they doThe technician runs a programme with spin and checks the drum ends empty and E20 does not return.
They must show youthe drum empty at the end.
In writingprogramme, result and date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Hose position and height
- Who:
- you, with a tape measure.
- How:
- check the drain hose goes no more than 10 cm into the pipe and the drain is between 60 and 100 cm high from the washer base.
- Result that matters:
- hose and height within those values, with no kinks or twists.
- If it was outside those values or kinked:
- correct it and try a programme.
- If everything complies:
- clean the filter and pump.
- Evidence to keep:
- a photo with the tape measure.
Evidence: Zanussi washing machine not draining, error code E20 or E21
Filter and pump
- Who:
- you, with the washer unplugged.
- How:
- open the filter cover, drain the water into a container, remove debris from the filter and, if you can see the pump blade, turn it with a pencil; then run a hot wash without detergent, as Zanussi says.
- Result that matters:
- a clean filter and a blade that turns freely.
- If there was debris and it then drains without E20:
- that was the cause.
- If it was clean:
- try draining into a bowl.
- Evidence to keep:
- a photo of the filter and what was removed.

Drain test into a bowl
- Who:
- you.
- How:
- put the end of the hose in a bowl or the sink and run a drain programme.
- Result that matters:
- the water flows out normally.
- If it drains fine this way:
- the blockage is in the household trap or connection.
- If it still does not drain:
- unplug the washer for 1 to 2 hours in case the pump protected itself and, if E20 returns, book a technician.
- Evidence to keep:
- a short video of the water flowing or not.

What it means
Zanussi explains that E20 (and E21 to E24 or C2) appears when the washer cannot drain within the expected time. The causes it gives are a blocked drain filter, a restriction in the drain hose or a drainage system fault. It also names excess foam, which blocks the level system, and a blocked pump that protects itself with a thermal fuse. The code is not enough to declare the pump failed.
Warnings and stop conditions
- Mediumeditorial warning
Unplug the washer before opening the filter and use a container: water will reach the floor next to an electrical appliance. If the programme was hot, let it cool.

Symptoms and causes
Probable causes · in order
- Blocked drain filterCommon
You can tell on opening the filter and finding debris; after cleaning it and a hot wash without detergent, it drains.
Evidence: Zanussi washing machine not draining, error code E20 or E21
- Kinked, pushed in or badly extended hoseCommon
Zanussi says it must go no more than 10 cm into the drain, with no kinks, checking the joints if it was extended; it shows when you inspect the route.
Evidence: Zanussi washing machine not draining, error code E20 or E21
- Drain at the wrong height or blockedPossible
The height must be between 60 and 100 cm; if it works when draining into a bowl, the blockage is in the household trap.
Evidence: Zanussi washing machine not draining, error code E20 or E21
- Blocked pump protected by its thermal fusePossible
Zanussi says a blocked pump is switched off by a bimetal fuse; after 1 to 2 hours without power it works again if it has freed up.
Evidence: Zanussi washing machine not draining, error code E20 or E21
