Hiya Moxon,
Can you post the make and model of the appliance please?
Thanks
Hiya,
The thermostats will most likely have gone on this one.
Unplug the appliance from the wall socket and turn the machine around.
Take off the rear panel and test the thermostats using a multimeter.
If you have any flashing lights or indicator lights lit, let me know.
Hope this helps.
