Hotpoint dryer not heating.
Looked at this dryer in the past (no heat) checked the thermostats, elements etc. all ok. Tried machine and it started working. Approximately 12 months later the dryer is not working again.Thermostats and elements are ok. One of the buttons that has a thermometer image is permanently lit, also when you turn the machine on and press start nothing happens then if you turn it off at the plug and turn it on again the machine will start to work the drum goes round but no heat. Any ideas please
