If your dryer button is not sticking in, you need to replace the relay pcb module which is situated just behind the front bezel. This module contains a relay which is not catching anymore. Remove 3 screws from top of lid at back of machine.
Slide wooden lid off.
You will see the wire harness at front by timer.
You need to change the little (match box size) module which has about 5 wires going to it.
Will cost you about 12 -15 quid
Call the manufacturer and they will charge over £100 call out.
Easy job to do youself
Phone up hoover parts dept and they'll sell you the part.
Hope this helps
