Edesa F03 on a washing machine: drainage fault, water not drained

Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On Edesa washers such as the EWF-9400 WH, F03 means a drainage fault: the machine cannot get the water out. Check the drain hose is not pinched or frozen, that water flows through it and that the filter is not clogged.
Safety first
Stop and check this first
- This code table is from the Edesa EWF-9400 WH manual; on other Edesa models the same code may mean something else, so check your model's manual.
- The water inside may be hot: wait for it to cool and unplug the washer before opening the pump filter, with a cloth on the floor in case it spills.
Safe checks you can perform
- Check the drain hose route
- Drain the water and clean the pump filter
- Restart and repeat the programme

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 diagnosis
What they doThe Edesa authorised technician checks why the water does not leave: hose, filter and the drain circuit inside the machine.
They must show youwhere the blockage or fault was and the part involved.
In writingthe cause found, the part replaced with its reference and the reason.
Test programme with a full drain
What they doAfter the repair, the technician runs a programme with a spin and checks that the washer drains and finishes without F03.
They must show youthe programme finished without F03 and no water left in the drum.
In writingthe programme used, the result and the date of the test.
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.
Check the drain hose route
- Who:
- you, with the washer switched off and unplugged.
- How:
- pull the washer out a little and follow the drain hose from the back to the sink, bath or wall drain. Check it is not pinched, kinked, damaged or frozen. Edesa says the end must sit 60 to 100 cm above the floor and be secured so it cannot slip.
- Result that matters:
- ruling out the hose stopping the water from leaving.
- If it was pinched, kinked or frozen:
- fix it (let it thaw by itself) and repeat the programme.
- If the hose is clear and properly placed:
- clean the pump filter.
- Evidence to keep:
- photos of the hose route and of the height of its end.

Drain the water and clean the pump filter
- Who:
- you, with the washer unplugged and the water cooled.
- How:
- lay an absorbent cloth on the floor and make sure the water has cooled. Open the pump filter cover; if there is an emergency drain tube, pull it out, put it in a container, remove its plug and let the water out; if not, put the container under the filter. Turn the filter slowly anticlockwise, take it out, rinse it under running water and refit it clockwise with a clean seal surface.
- Result that matters:
- a clean, properly closed filter that does not hold back the drain.
- If there was fluff, buttons, coins or hairpins:
- after cleaning, repeat the programme.
- If the filter was clean:
- do the restart Edesa suggests.
- Evidence to keep:
- photo of the filter and what came out, and roughly how much water.

Restart and repeat the programme
- Who:
- you.
- How:
- switch the washer off, wait a few seconds, switch it on again and repeat the wash programme, as the troubleshooting section says. Watch whether it drains and spins.
- Result that matters:
- knowing whether F03 returns with the hose and filter already checked.
- If it drains and finishes without F03:
- keep an eye on the next washes.
- If F03 returns:
- call the Edesa authorised service.
- Evidence to keep:
- photo of the code on the display and the programme it appeared in.

What it means
The error table in the official manual for the Edesa EWF-9400 WH defines F03 as a drainage fault. Edesa asks you to check whether the hose is pinched and water flows through it, whether the drain filter is clogged and whether the hose is frozen. The manual adds that the pump filter should be cleaned when the appliance cannot start the spin cycle or there is debris in the pump. Then switch off, wait a few seconds, switch on and repeat the programme; if it persists, call the authorised service. The code alone never proves that a part is faulty.

Symptoms and causes
Probable causes · in order
- Clogged drain filterCommon
Edesa asks you to check whether the filter is clogged; the manual says to clean the pump filter especially after washing woolly or very old laundry, or if buttons, coins or hairpins got in.
Evidence: Edesa EWF-9400 WH manual de instrucciones (ES/EN/FR/PT)
- Drain hose pinched or kinkedCommon
The F03 table asks whether the hose is pinched and whether water flows through it; a hose trapped behind the machine blocks the outflow.
Evidence: Edesa EWF-9400 WH manual de instrucciones (ES/EN/FR/PT)
- Frozen hoseLess common
Edesa lists a frozen hose among the F03 checks, which can happen if the washer stands somewhere that drops below freezing.
Evidence: Edesa EWF-9400 WH manual de instrucciones (ES/EN/FR/PT)
- Drain hose badly installedPossible
The manual says the hose end must sit 60 to 100 cm above the floor and that incorrect installation can make the machine work abnormally.
