Ok this dishwasher is made by Smeg and sometimes you can reset there control boards.
Try this and see what happens.
Switch on, don't wait for any lights.
As soon as you press the on button, press the programme button 4 times within 2 seconds.
The two end programme lights should come on flashing.
Press the programme button once.
The 1st light will go out.
The 5th light will continue flashing.
Wait 10 seconds.
Try this and see if it resets the control board and let me know.
Hi Daniel, have just tried the reset, but it immediately shows a symbol of wavy lines with a x over them and 1/2 to the right of them. You can press the program button and it cycles the the programs plus A1 , 2 and 3 ?. It them shows 62 on the left side of the panel !
Ok if its not resetting the control unit then its usually down to a faulty control board itself.
So there isn't much else you can do to reset it its a case of replacing the board now im afraid.
Thought that might be the case, and as some people carry them in stock, it seems to point to it.
Kind regards Pete
