Hoover Wdyn856 washer dryer not heating on drying cycle

The problem

A Hoover Wdyn856 washer dryer would not dry clothes and produced no heat on tumble dryer mode. The fan was reported to run, but only blew cold air.

Likely cause

The accepted reply said that, given the parts already replaced, the most likely remaining cause was a wiring or connection fault. A control unit fault preventing power being sent to the dryer circuit was mentioned only as a possibility, not a confirmed diagnosis.

What fixed it

No confirmed repair was documented. The accepted advice was that after replacing the thermostat, pressure switch, heating element and the four-wire component, the remaining likely area to investigate was wiring/connections rather than guessing further parts. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Checks to try

• Fan runs but only blows cold air
• Thermostat replaced
