Im about ready to knock this one on the head.
The brush has no voltage going to it.
There is 240V ac going in to the head pcb but im struggling to measure components as the pcb is covered in white silicone.
The white leds illuminate so some of the pcb is working but no volts at brush motor,
Has anyone come across this and found out what fails on the pcb.
Had this once before but fixed it using the head from a scrap machine.
