Bosch WAA28161GB/09 surging motor

Could some kind soul please tell me what Tacho readings I should get on the motor for the above ?
The machine is surging then cutting off.

if you spin the motor and set your meter on low ac volts you should see an output. if no output check for broken magnet

is it a controlled surge ie does it speed you quickly or instantly

if instantly suspect also the motor triac

measure motor from board to rule out broken wires duff connectors etc

Thanks Dave, I’ve ruled our motor now must be the board.
I’ve not had problems with motor triacs before on Bosch machines.
