You need to check the service manual for your machine. Compared to an engineer call-out charge, this guy on Ebay can apparently supply most makes/model SERVICE, not USER manual which has all the codes for the LEDs and beeps. I have a Zanussi Aquacycle 1500 and suddenly on start-up it was clicking 3 times at the door switch then repeatedly beeping 4 times. I removed the switch, (Mains OFF) carefully opened it up and saw 'charring' so guessed it was worn out. Could be wrong but I'll risk a straight replacement of a £15 part that I can always keep as a spare if Im wrong! :-) Try that guy though, for a tenner you will always be able to de-code beeps.
