E6
Haier E6 on a tumble dryer: lint or condenser filters clogged
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On Haier heat pump dryers, E6 means the filters are clogged. Unplug the dryer, clean the lint filter in the door opening and the condenser filter in the base, then clear fluff from the front of the heat exchanger and the ventilation slots.
Safety first
Stop and check this first
- The heat exchanger holds HFKW-134a gas in a sealed circuit: do not pierce or bend it, and leave any repair to customer service.
- Unplug the dryer before cleaning the filters or heat exchanger, as Haier requires for any maintenance task.
Safe checks you can perform
- Clean the lint filter in the door opening
- Clean the condenser filter in the base
- Clear the heat exchanger front and the vents
- Never dry without filters or with damaged ones
Leave these tasks to a qualified professional
- Do not attempt this professional task: Airflow inspection by Haier customer service
- Do not attempt this professional task: Test programme with filters fitted
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.
Airflow inspection by Haier customer service
What they doIf E6 persists after cleaning the filters, heat exchanger front and vents, the Haier technician inspects the internal air path and the heat exchanger behind the filters.
They must show youwhere the blockage was and the fan moving air after the repair.
In writingthe code read, what was blocking the air, any part replaced and the test carried out.
Test programme with filters fitted
What they doAfter the work, the technician runs a programme with both filters fitted and confirms it finishes without E6 coming back.
They must show youthe dryer finishing the programme with no E6 on the display.
In writingthe programme used, how long it ran and that it ended with no code.
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.
Clean the lint filter in the door opening
- Who:
- you, with the dryer switched off and unplugged.
- How:
- take the lint filter out of the drum, open it and wipe off the fluff with a damp cloth or wet hand. If you see a detergent film, wash it with warm water and a soft brush. Also remove fluff from the filter housing and the seal before putting it back.
- Result that matters:
- a clean filter with no detergent coating, seated properly.
- If the filter was blocked:
- after cleaning, run a programme and see whether E6 is gone.
- If it was already clean:
- move on to the condenser filter in the base.
- Evidence to keep:
- photo of the lint filter dirty and then cleaned.
Evidence: User manual Heat-Pump-Dryer HD90-A636 (GB V07 082016)
Clean the condenser filter in the base
- Who:
- you, following the Haier manual.
- How:
- with the dryer unplugged, open the service door at the bottom, open the four levers and pull out the condenser filter. Remove the rear filter screen and clean it with a damp cloth, or under running water if it is very dirty. Refit the screen and reinstall the filter in reverse order, closing the levers.
- Result that matters:
- the condenser filter clean and all four levers closed.
- If it was packed with fluff:
- with both filters clean, E6 should stop appearing.
- If both filters were clean:
- check the front of the heat exchanger.
- Evidence to keep:
- photo of the clean condenser filter and rear screen.
Evidence: User manual Heat-Pump-Dryer HD90-A636 (GB V07 082016)
Clear the heat exchanger front and the vents
- Who:
- you, wearing household gloves.
- How:
- with the condenser filter out and the dryer unplugged, remove fluff from the front of the heat exchanger with a sponge or vacuum cleaner; Haier notes it comes off more easily if you spray it with water first. Vacuum the ventilation slots too. Do not push hard tools between the fins.
- Result that matters:
- no visible fluff on the heat exchanger front or the ventilation slots.
- If there was a lot of fluff:
- refit the filter and run a programme.
- If E6 returns with everything clean:
- switch the dryer off, unplug it and contact Haier customer service.
- Evidence to keep:
- photo of the cleaned heat exchanger front and a note of the date.
Evidence: User manual Heat-Pump-Dryer HD90-A636 (GB V07 082016)
Never dry without filters or with damaged ones
- Who:
- you.
- How:
- when refitting, check that neither filter is torn and that both sit in place. Haier forbids running the dryer without the lint filter or the condenser filter, or with either one damaged, because fluff would then reach the heat pump.
- Result that matters:
- both filters intact and fitted before you switch on.
- If a filter is torn:
- do not use the dryer until you have a replacement from Haier service.
- If they are fine:
- keep using it and clean them after every cycle.
- Evidence to keep:
- photo of any tear you find in a filter.

What it means
The user manual for the Haier HD90-A636 heat pump dryer (GB edition V07, 2016) lists E6 with a single cause, filters are clogged, and a single fix, clean the filters. The dryer has a lint filter in the filling opening and a filter in the base that protects the heat pump, and Haier asks for both to be cleaned after every cycle. If the code comes back after cleaning, it says to switch off, disconnect the power and call customer service. Other models may use other codes. E6 by itself is no proof that a dryer part has failed.

Symptoms and causes
Probable causes · in order
- Lint filter full or coated with detergentCommon
Fibres shed by the laundry collect in the filter at the filling opening, and detergent residue can form a coating that holds the air back.
Evidence: User manual Heat-Pump-Dryer HD90-A636 (GB V07 082016)
- Dirty condenser filter in the baseCommon
Fluff builds up gradually in the base filter that protects the heat pump, and Haier warns it may affect how the dryer works.
Evidence: User manual Heat-Pump-Dryer HD90-A636 (GB V07 082016)
- Fluff on the heat exchanger front or ventsPossible
When the heat exchanger front is not cleaned about every 10 cycles and the ventilation slots are not vacuumed, fluff restricts the airflow.
Evidence: User manual Heat-Pump-Dryer HD90-A636 (GB V07 082016)
