MW051 blows start switches

G’day,

First thanks for your assistance. Using existing posts on this forum I have successfully diagnosed a failed ‘Out Of Balance’ micro and replaced it. Shortly afterwards the ‘Start’ switch on the board stopped working. I swapped it with the ‘Heavy Duty’ switch as I rarely use that selection but about 6 weeks later it has blown again. As a temporary measure I have connected a heavy duty switch via a couple of wires. Not ideal, but allows the family washing to be done.

Any ideas why it would chew through these switches. Also I have noticed that I can’t seem to get into the diagnostics in the manner mentioned in the sticky note. I’m sure that it sort of worked when I had the OOB micro problem but this time round all I got when holding ‘Temp Down’ and ‘Power’ was no beeps, 1 rinse light and 1 water level light.

Any ideas would be greatly appreciated.
