My integrated Diplomat dishwasher has a fault whereby all the lights come on when the power button is pressed and I am unable to select a program. I have switched on and off a few times pressed both buttons and then all of a sudden it rights itself and I can use it. But, at the end of the wash it leaves all the lights on and are unable to use it again. Have replaced the pcb behind the light panel. Any ideas please
