As usual, I have come to the UK White Goods forum for help on a repair…
We have a built in Smeg washer dryer which keeps tripping the TOC on drying cycle.
We have replaced condenser and front bellows, cleaned fan blades and cleaned fan ducting, also replaced trip with new one and also advised customer to dry half loads.
a few things come to mind
whats the model no ?
The Thermostat isn’t doing its job.
The customer is switching it off early so its not doing the cool down.
