Whirlpool F05 on a washing machine: drain blockage or pump issue
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
F05 on a Whirlpool washing machine means a waste pipe blockage or a pump issue: water stays in the drum or the door will not open. Check the pump filter, the waste water hose and the under-sink plumbing.
Safety first
Stop and check this first
- Draining the filter releases dirty water that may be hot: let it cool, unplug the machine and do not force the door open with water inside.
Safe checks you can perform

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 test
What they doWith the machine disconnected, the engineer reaches the pump, checks whether it turns and empties the drum, and checks its connection against Whirlpool's specification.
They must show youthe pump tested, the result of the drain test and the state of the filter and hose.
In writingthe cause found, the part replaced with its part number and the reason.
Final drain and spin cycle
What they doAfter the repair, the engineer runs a drain and spin cycle in front of you and checks the drum ends up empty and the door opens.
They must show youthe complete cycle without F05 and the drum empty at the end.
In writingthe test carried out, the result and the 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.
Pump filter
- Who:
- you, with the machine switched off and unplugged, if your model has an accessible filter.
- How:
- check your model's handbook for a pump filter and how to drain it; put down a container and towels, let the water out slowly and clear the filter.
- Result that matters:
- whether the filter held fluff or objects that were slowing draining.
- If it was dirty or held objects and the machine now drains:
- that was the cause.
- If it was clean or your model has no accessible filter:
- move on to the waste hose.
- Evidence to keep:
- photo of what was in the filter and the date.

Waste water hose
- Who:
- you, without opening the machine.
- How:
- follow the waste hose from the back of the machine to the drain and look for kinks, squashing behind the unit or a visible blockage at the end.
- Result that matters:
- whether the water has a clear path from the machine to the drain.
- If it was kinked or blocked and drains once fixed:
- the pump is ruled out.
- If the hose is fine:
- check the house drain.
- Evidence to keep:
- photo of the hose route before and after repositioning it.

Under-sink plumbing
- Who:
- you.
- How:
- if the hose goes into the sink trap or a standpipe, check whether the sink drains freely and whether there is debris where the hose enters.
- Result that matters:
- separating a house plumbing blockage from a problem in the machine.
- If the sink also drains slowly or the inlet is dirty:
- it is a house blockage, not the machine.
- If everything drains well and F05 keeps coming back:
- ask the service to check the pump.
- Evidence to keep:
- note of how the sink drains and photos of the drain inlet.

What it means
In Whirlpool Service UK's official table, F05 means waste pipe blockage or pump issue. The symptoms it lists are that the door will not open, or opens but water remains inside the drum. The control sees that the water is not leaving in time, but not where the blockage is: it can be the pump filter, the hose or the house plumbing. The code alone does not prove the pump is faulty; Whirlpool only points to it once the three checks have not solved it. There is no matching page on whirlpool.es, so the Spanish entry follows the UK page.

Symptoms and causes
Probable causes · in order
- Blocked pump filterCommon
Fluff, coins or buttons in the filter slow draining; it is the first check Whirlpool asks for, on models with an accessible filter.
Evidence: Whirlpool | Washing Machine Error Codes | Whirlpool Service
- Blocked waste water hoseCommon
A blockage or kink in the waste hose stops the water even if the pump works; you can tell because the filter is clean.
Evidence: Whirlpool | Washing Machine Error Codes | Whirlpool Service
- Blocked house drainPossible
If the washer drains into the sink trap or a standpipe, a blockage there slows or returns the water; Whirlpool asks you to check it.
Evidence: Whirlpool | Washing Machine Error Codes | Whirlpool Service
- Drain pump failurePossible
Whirlpool says that if none of the above works, a pump failure is likely; the engineer confirms it, not the code.
