Teka E21 on a TKD washing machine: drain time exceeded
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
On a Teka washing machine from the TKD range, E21 means the 3 minute drain time was exceeded. Teka names a pinched drain hose or a blocked drain pump. Check first that the hose is not pinched.
Safety first
Stop and check this first
- Unplug the washer before moving it to check the drain hose: water may come out next to an electrical appliance.
Safe checks you can perform
- TKD range model
- Pinched drain hose
- Drain service test

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 measurement
What they doWith the washer unpowered, the technician measures the pump impedance with a multimeter; the Teka TKD manual gives about 150 to 250 ohms at 230 V.
They must show youthe measured value against the range in the Teka manual and any object removed from the pump.
In writingmeasured value, result, the pump reference if replaced and why.
Service test and test wash
What they doThe technician runs the service test that activates the pump and a programme with a full drain.
They must show youthe test without E21 and the tub empty.
In writingtest done, 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.
TKD range model
- Who:
- you, no tools.
- How:
- read the appliance label and check whether the model is TKD 1270, TKD 1280, TKD 1480, TKD 1490 or TKD 1610 WD.
- Result that matters:
- knowing whether your washer belongs to the range the manual covers.
- If it is a TKD:
- E21 means drain time exceeded; go on to the hose.
- If it is another range:
- the meaning may differ; check your model manual.
- Evidence to keep:
- a photo of the model label.

Pinched drain hose
- Who:
- you, with the washer unplugged.
- How:
- carefully pull the washer away from the wall and check the drain hose along its whole route.
- Result that matters:
- a hose with no crushing or pinching.
- If it was pinched and it drains without E21 once freed:
- that was the cause.
- If it is clear:
- the next suspect is the pump; book a technician.
- Evidence to keep:
- a photo of the hose before and after.

Drain service test
- Who:
- technician.
- How:
- runs the TKD service test, which activates the drain pump, and measures the pump with no power.
- Result that matters:
- whether the pump drains in the test and whether its winding measures within the Teka figure.
- If the pump does not drain but measures fine:
- it points to a mechanical blockage.
- If the reading is out of range:
- it confirms a pump fault.
- Evidence to keep:
- a job sheet with the measured value.
The service test and pump measurement are technician work: they involve mains voltage and opening the appliance.

What it means
In the Teka service manual for the TKD range (TKD 1270, 1280, 1480, 1490 and 1610 WD), E21 means drain time exceeded: the washer does not empty the tub within 3 minutes. Teka gives two possible causes, a pinched drain hose and a blocked drain pump. Codes differ in other Teka ranges, so confirm your model is a TKD. The code does not prove the pump has failed.
Warnings and stop conditions
- Mediumeditorial warning

Symptoms and causes
Probable causes · in order
- Pinched drain hosePossible
Teka names it as a cause; you can tell because the hose is visibly crushed or bent behind or under the washer, and it drains once freed.
Evidence: Teka Manual de Servicio MSWM15043 ES gama lavadoras SPA (TKD)
- Blocked drain pumpPossible
If the hose is clear, Teka points to a blocked pump; the technician checks it in the service test.
