EX600 Electrolux Diashwasher

Question

My Diashwasher will not repond to touchpad buttons.
The only way we can get the machine to begin a wash cycle is to use the delay button, the start/stop button does not respond at all.

Yet the machine can start cycle by using the delay button only,,but we have to wait 1 hour every time we need to use the machine..Any on know what the problem is
