Whirlpool WWDC9440 F06 fault-tried everything!
Hi all,
I have a whirlpool WWDC9440 which keeps giving me an F06 fault. I have only recently changed the bushes and when I had it out the last time they still have plenty of meat on them. When it did it the last time I tested the continuity on the motor and it seemed good. The belt is fine. I am running out of things to check! Could it be anything else apart from the motor is knackered. It is six years old.
Thanks

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Whirlpool WWDC9440 showing F06, motor circuit fault suspected
- The problem
- A Whirlpool WWDC9440 washer-dryer repeatedly showed fault code F06. The owner had recently replaced the motor brushes, reported the belt was intact, and said a continuity test on the motor seemed OK, but the fault persisted.
- Likely cause
- The accepted advice was that F06 on this model range is often linked to the motor circuit or speed feedback. Possible causes mentioned were brushes not moving or bedding correctly, a worn or damaged commutator, wiring loom or motor plug faults, a faulty or loose tacho coil or magnet, or a motor control/main PCB fault. The motor itself was not confirmed as failed.
- What fixed it
- Recommended action was to isolate the appliance and recheck the motor brush condition and movement, inspect the commutator, inspect the motor connector and wiring loom back to the PCB, and check the tacho coil and magnet. It was also noted that simple continuity testing is not enough to prove the motor is healthy. If those checks do not identify the cause, PCB or motor-circuit diagnosis by an engineer was advised. No completed repair was confirmed in the discussion.
- Checks to try
- Motor brush condition, free movement, spring pressure and bedding-in
- Commutator condition for burning, blackening, pitting or raised segments
- Motor plug and wiring loom back to the main PCB for loose pins, overheating, broken wires or corrosion
- Tacho coil and rear motor magnet for looseness or damage
- Resistance checks on tacho and motor windings
- Check for insulation faults to earth
- Parts or tools mentioned
- Motor brushes
- Drive belt
- Motor
- Tacho coil
- Main PCB
- Meter
Safety: Isolate the appliance from the mains before removing panels or unplugging components. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Hi,
On many Whirlpool washer-dryers an F06 is often related to the motor circuit or speed feedback, but I would not jump straight to condemning the motor if the brushes are still good. There are a few other common causes worth checking first.
1. Isolate the appliance from the mains before removing any panels or plugs.
2. Recheck the motor brushes properly: - Make sure they slide freely in the holders. - Check spring pressure is good. - Confirm they are bedded in correctly on the commutator and not chipped or sticking.
3. Inspect the commutator on the armature: - Look for heavy burning, blackening, pitting, or raised segments. - If badly worn, the motor can still fail even with decent brushes fitted.
4. Check the motor plug and wiring loom all the way back to the main PCB: - Look for loose pins, overheating, broken wires, or corrosion. - Pay particular attention where the loom flexes and near the motor connector.
5. Check the tacho coil on the rear of the motor: - Make sure the magnet is secure and the coil is not loose or damaged. - A failed or intermittent tacho can cause a motor-related fault even when the motor windings test OK.
6. If you have a meter, compare resistance of the tacho and motor windings and check for insulation faults to earth if possible. Simple continuity alone does not prove the motor is healthy.
7. If all of the above checks out, the fault could be on the motor control/main PCB rather than the motor itself.
At six years old it is still worth diagnosing properly before replacing major parts. If you are not confident with live electrical testing or PCB diagnosis, it is best to get a qualified appliance engineer in.

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
