okay i should not be saying this as work for Hotpoint
the one shot stat has operated so need to replace the stats remove the heater cover on the back on the machine always turn off the power please, there 2 round objects with wires attached to them they are the stats, the stats have coloured dots on them, the one of them will have a green spot on on it this the one at fault and the shiny face of the stat will be concave in shape instead of convexed like the other stat, what it means you dryer has got too hot your local hotpint spares shop will be able to get them from there. replace them in the correct order you found them in, replace the heater cover then clean out the condenser unit and fluff filter and it should work again
hope this works for you it should do
