If it's rotating with no heat, it could be the heating element, or the overheat trip - assuming the wiring/switch is OK.

The overheat trip may or may not be a resettable type. If it has tripped, usual cause is poor air circulation (fluff) in element.

Hi rotating with warmish air plus checked no fluff in filter wiring switch ok
I think i need open rear to check reset? ( will it rotate if there was 7no trip?)

Trip only cuts the element off. You suggest it is getting warmish. Warmish might suggest the thermostat is set to low/ out of adjustment.

Thermostat set highest ( extra dry) perhaps warmish not correct i say cold air

Update! Heat element plus trip switch checked wiring all good zero fluff inside element ( neighbour checked with multi metr)

That makes sense, but you will need to ask the experts on ukwhitegoods.
