Ok try this and see what happens and let me know its a short test cycle. Turn the dishwasher on. (by the on/off button)Turn it off again.Press and hold the start button for 3 seconds.Then turn it back on.Press start again. Now it will run the short test cycle. Let it complete the cycle and then turn it off.Then turn it back on again and see how it goes from there and let me know. Regards

Customer: replied 2 years ago.
not like the on off button
Customer: replied 2 years ago.
I suppose I could remove the module behind the start button
Expert:  Daniel replied 2 years ago.
Hi
Ok remove the control panel and take the control board off and check the buttons behind there.
Then refit and retry it from there. As to be honest this sounds like the front board isnt responding to the start button being pressed.
Check that and see what you find and let me know.
Regards
Customer: replied 2 years ago.
ok
Expert:  Daniel replied 2 years ago.
No worries, Let know how it goes.
Customer: replied 2 years ago.
ok. finished the strip and replace
Customer: replied 2 years ago.
the start button seems to just sit on the module
Expert:  Daniel replied 2 years ago.
Ok im taking it its still not working?
If so then its going to be a faulty module unit. Remove it and open the plastic casing and sometimes the push button thats attched onto the board breaks off so the buttons doesnt actually press aganst anything. If this has happened then the board will need to be replaced here.
Customer: replied 2 years ago.
sorry my PC stopped responding
Expert:  Daniel replied 2 years ago.
No worries
Customer: replied 2 years ago.
