Got a Bendix washing machine which is emiting the fault code 3 sets of 4 beeps end light flashes followed by a long bleep then repeats ad infinitum with pump activated.
As a rule on this model you need to count the flashes firstly of the ‘End’ LED and the ‘Start/Pause’ LED. The combination of which = the error code.
As I read from what you say that the END LED flashes 4 times (does it?) In that case the fault being associated with a Door Interlock and/or Interlock triac blown on the main PCB 😉
