E21
Haier E21 on a dishwasher: water flows in unchecked, shut the tap
Risk level
High
Professional inspection is recommended.
Urgency
High
Quick answer
On Haier dishwashers, E21 means an uncontrolled water supply with the solenoid valve open. Haier asks you to close the water tap immediately and disconnect the dishwasher from the power supply; then call the technical service.
Safety first
Stop and check this first
- With E21 water may keep flowing in: do not leave the tap open or the appliance plugged in hoping it fixes itself, because the risk is a flood with live parts nearby.
Safe checks you can perform
- Close the tap and disconnect now
- Do not move or tilt it with water inside
- Look at the supply hose and its safety devices
Leave these tasks to a qualified professional
- Do not attempt this professional task: Diagnosis of the water inlet
- Do not attempt this professional task: Supervised test fill
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.
Diagnosis of the water inlet
What they doThe technician tests the inlet solenoid valve and what controls it to find out why water enters without the appliance calling for it.
They must show youthe solenoid valve test and its result.
In writingthe cause, any part replaced and its reference.
Supervised test fill
What they doAfter the repair, the technician opens the tap, runs a programme and checks that filling stops at the right level.
They must show youa fill that stops by itself and a programme without E21.
In writingthe level at which filling stopped and the test 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.
Close the tap and disconnect now
- Who:
- you, as soon as you see E21.
- How:
- close the tap that feeds the dishwasher and pull the plug from the socket, which is exactly what Haier asks for this code. Do it with dry hands.
- Result that matters:
- water stops coming in and the appliance has no power.
- If water is already on the floor:
- wipe it up only after unplugging.
- If everything is dry:
- keep the tap closed anyway until the repair.
- Evidence to keep:
- photo of the display showing E21 before unplugging, if it is safe.

Do not move or tilt it with water inside
- Who:
- you.
- How:
- leave the dishwasher where it is. Haier recommends not moving or tilting it during operation so the overflow safety device works properly, and moving it only when no water remains inside.
- Result that matters:
- not upsetting the overflow protection or spilling the water inside.
- If you need to pull it out:
- wait for the technician to empty it.
- If it can stay where it is:
- do nothing more with it.
- Evidence to keep:
- note of whether there was water in the tub when you opened the door.

Look at the supply hose and its safety devices
- Who:
- you, with the Haier unplugged.
- How:
- if your model has Aquastop, look at the window on the supply hose: a red mark means the hose has deteriorated and must be replaced. If it has Waterblock, check the box at the tap connection without cutting or opening the hose, which contains live parts.
- Result that matters:
- giving the technician information about the state of the supply hose.
- If you see the red mark or the box is damaged:
- keep the appliance unplugged and tell the technician.
- If there are no visible signs:
- the valve diagnosis is for the technical service.
- Evidence to keep:
- photo of the Aquastop window or of the connection box.

What it means
The error table in the manual for the Haier XF 6B0M3PDA dishwasher (edition 24.11) defines E21 as an uncontrolled water supply with an open solenoid valve. In other words, water keeps entering when the appliance is not asking for it. Haier gives two immediate actions: close the tap and disconnect the appliance from the power. The manual explains that all its dishwashers have an overflow safety device that cuts the inflow or drains the excess if water goes above the normal level. The code points to the symptom and does not by itself confirm the solenoid valve is broken: that check belongs to the Haier technical service.
Warnings and stop conditions
- Higheditorial warning
With E21 water may keep flowing in: do not leave the tap open or the appliance plugged in hoping it fixes itself, because the risk is a flood with live parts nearby.

Evidence: Haier dishwasher XF 6B0M3PDA user manual (70060922)
- Water above the normal levelPossible
When water goes above the expected level because of a fault, the overflow safety device cuts the inflow or drains the excess, as the installation section explains.
