Hi, My trusty Zanussi is (was) still going strong after 15 years. However, lately when I push in the on/off switch to power the machine up, the switch doesn't stay in the on position - it pops back out again. I guess that the switch is worn out - but how do I get access to it. I can't see how to get the front panel off. Thanks in anticipation.
