Answer to continue safely
Is it safe to keep using?
No. The machine will not run cycles with F5 active. The door safety switch is a critical safety component — do not attempt to bypass or tape the door closed.
Can I reset the code?
Yes. A 60-second mains power reset clears F5. If the door latch and seal are physically intact the machine may restart normally. Recurring F5 requires switch replacement.
When to stop immediately?
Stop if you notice: The door cannot be opened after an F5 fault and drum contents are visible through the glass — do not force the door., F5 recurs on every start attempt even after confirming a clean seal and intact door hook..
Symptoms You May Notice
Dryer drum does not start after pressing the start button
Pressing start produces no motor response — the drum does not rotate, the heater does not activate, and F5 is displayed within a few seconds of the start attempt.
Running cycle stops abruptly when door is nudged
A cycle that is running normally halts immediately if the door is slightly jostled — the door switch is making intermittent contact and losing the closed signal under vibration.
Door appears fully shut but F5 persists
Visually the door is closed and the latch is engaged, but F5 remains on the display — indicating an electrical fault in the switch circuit rather than a mechanical door problem.
Clicking sound from door latch area during failed start attempt
A repeated clicking from the door latch zone as the machine attempts to start and then stops suggests the door switch is receiving an intermittent signal and repeatedly re-checking the door state.
Possible Causes
Worn or broken door latch hook
The plastic door hook that depresses the switch plunger may have worn down or snapped, not pressing the switch far enough to close the circuit.
DIY PossibleFailed door safety switch
The micro-switch inside the door catch assembly has failed — either its contacts have worn open, or the plunger mechanism is broken. This is a mechanical part that wears with repeated open/close cycles.
Requires ProfessionalLoose wiring connector on door switch
The wire terminals on the door switch have worked loose due to vibration, creating an intermittent open circuit in the door-closed signal line.
DIY PossibleSafe Checks You Can Do
-
1
Inspect the door latch and hook
Open the dryer door and examine the plastic hook on the door that engages the switch strike on the machine body. Check for visible cracks, chips, or wear on the hook tip. Close the door slowly and feel whether it clicks firmly into the catch. A hook that slides in loosely without a firm click is likely worn.
On Asko T-series dryers the door hook is part of the inner door panel assembly. It can often be popped off with a flat-head screwdriver to inspect the engagement depth.

2
Check for obstructions in the door seal
Run your fingers around the full circumference of the door seal. Lint accumulation or a small garment item caught in the seal prevents the door from closing flush, stopping the latch from engaging the switch fully.
Dryer door seals accumulate lint faster than washer seals — wipe the seal with a damp cloth weekly on high-use machines.

3
Power cycle and attempt restart
Power the dryer off at the mains for 60 seconds. Ensure the drum is empty, close the door with a firm push, and restore power. Select any 30-minute timed programme and press start. If the drum begins to rotate and the cycle starts, the fault was a transient switch misread.
If the machine starts once but F5 returns on the next cycle, the door switch is failing intermittently and needs replacement before it fails completely.
When to Call a Professional
Contact a qualified technician if:
- Door hook and seal are intact but F5 persists — door switch micro-switch needs continuity testing and replacement.
- Door switch replacement on Asko T-series dryers starts from $85 including parts and fitting.
- Wiring harness connector on switch shows corrosion or loose terminals requiring professional repair.
