I have a Diplomat ADP8332 dishwasher?

Iam unable to get my machine to complete a wash cycle,if switched on i can set it to a normal wash cycle but after initially draining it seems to start its cycle but after 2-3 minutes it turns off without any error beeps only the start light is illuminated.
I have cleared the drip tray as has been suggested,is there anything i am overlooking or is there a way to return to factory settings effectively rebooting the system board?Any ideas would be greatly appreciated.
