When you turn it on do the lights come on?
If so then when you start it does the lock?
Ok if the other lights dont come on then what you can try is this.
Remove the top of the washer and there on the front right you will see the main power board. On there you will see lots of wiring blocks.
In the middle you should see a small blue or black wiring harness going from there through the front control panel to the front board.
Remove this wiring block from the main board and give the ends a gentle squess.
Then refit it and retry it and see if the lights come on then.
If not then you need to remove the front console panel and access the wiring block on that end of the board and do the same there and retry it. As bad connections on the communication cable between the 2 boards can causes this fault.
But if thats fine then remove the mian board from the cabinet and remove the back cover of it. There you will see the board. Check there for signs of burning on there. If it has blown then the control board will need to be replaced. But this is a very expensive part and giveen the age of the washer as this is comming up as a 2001 model its not worth it as you can get a new washer for just a bit more money.
But check that wiring cable first and see what you find.
These dont have sensor or float switches im afraid.
So are you saying the washer still runs in that the drum turns and the pump runs but just no lights are comming on?
Ok im with you.
It sounds like it could be a bad connection on the wiring with tilting it.
So remove the top and do as above and check the wiring block and see if its a bad connection on there.
If the wiring isnt the issue then im afraid its one of the electronic control boards at fault. We know the power supply is ok and the switch is as the orange light comes on.
So its the electronic control board at fault. Now most of the time its the main board tha fails on these which is the one on the side with all the wiring blocks on it. In this case the board will need to be replaced but as i said it is a very expensive fix on these.
Thats the thing with these faults like this. I can be working one minuite and then the next it goes without any warning.
