Indesit WIDXL126 led’s2&3 flashing and doorlock
Call to this machine because it had stopped and was not doing anything.
Put it on to drain door locked, no light though pump did try to run for 2/3 seconds then after a minute or two would do the same again eventually I got led’s2&3 flashing and doorlock led(not used in fault code guide) pump would run ok and drain.
It would do the same if I selected a wash program the valve would energise for 2/3 second then pause energise for 2/3 second again and so on until nothing seems dead, no fault code this time and door locked but no light
Have checked carbons, meggered motor, heater and machine all fine changed door lock still the same took main PCB and inspected it re-soldered 4 or 5 joints and tightened all the connections to the board did not help.
Any one got any suggestions
Thanks for looking
Bernie
