theres a clear plastic sort of framework behind the buttons... a bit like in an Airfix plastic plane kit, the plastic breaks & then the on/off doesnt work. Zanussi know its a fault on this model but did nothing about it, I packed ours out with some kitchen roll ( toilet tissue for big bums) in the back of the on/off button, it worked reliably until the electronics circuit board packed up ( another common fault on this model... replacement is £100+, & thats fitting it yourself!) If you ever get fault code E60 flash up, thats the circuit board.
I took ours to the tip yesterday & bought a Whirlpool vented dryer instead
