Last year my dryer on the above washing machine stopped heating up during the cycle.
I called an engineer who showed me a little trip switch on the top of the machine that just needed pressing down and he told me that in future that is all I need to do.
This was fine for months but now it has started happening again. And this time,when I press the trip switch down it only lasts until half way through the drying before it pops back out.
I have even tried to press it down half way and it pops back up after a few mintues.
Any ideas why this is happening and how I can resolve it?
