Hoover Wmh 168D Help Needed

Hi Karl,

What you describe is more likely a **motor feedback/control issue** than something that needs a simple reset. The machine is probably not “seeing” the motor speed correctly on spin, so it keeps trying to reach or control spin speed and gets stuck at 1 minute.

Before inspecting anything internal, **isolate the washing machine from the mains**.

1. **Recheck the new carbon brush** - Make sure it is the **correct type for this exact motor** and fitted the right way round. - Check both brushes move freely in their holders and have good spring pressure. - New brushes can spark a bit at first, but **heavy sparking on spin** suggests poor seating, the wrong brush, or a worn commutator.

2. **Inspect the motor commutator** - Look at the copper segments where the brushes run. - If it is badly burnt, rough, grooved, or uneven, the motor can misbehave especially at high speed.

3. **Check the motor tacho coil** - On many Hoover motors there is a **tacho coil/magnet** on the back of the motor. - If the tacho is loose, damaged, disconnected, or its magnet has cracked, the control board cannot regulate spin properly. - This is one of the most common causes of endless spin/1-minute sticking.

4. **Check motor wiring and plug connections** - Inspect the motor connector, loom, and pins for burning, looseness, or broken wires, especially around the tacho wires.

5. **Control module possibility** - If brushes, commutator, and tacho all check out, the **motor control section on the PCB** may be faulty.

The fact the lower-speed rapid cycle behaves better does point strongly toward a **high-speed motor feedback problem**. If you are not confident testing the motor/tacho with a meter, it would be best to get a **qualified appliance engineer** in. Any mains electrical, gas, or sealed refrigeration work should always be left to a properly qualified engineer.
