Got to this machine and as soon as you switch it on it clicks constantly from the timer. The customer says that it blew the house trip when it went originally.
On the board there is a fair old burn round the interlock connection and resistor R175 near to J14 connection.
I’m suspection interlock but would hate to replace both these and be left with something else. Anyone else had thie clicking. BTW the only light coming on is the power button led.
