I have a DIPLOMAT ADP 8312 dishwasher that will not run a complete cycle?

This DIPLOMAT will not run on any cycle and cuts out after about 10 minutes. When opened it displays one flashing (DELICATE) and one constant light (the setting it is on). When switched off and on again the two lights furthest on the right of the 5 lights illuminate which I assume is an error code but I know not what for. I've checked the salt and that is fine and I've checked the water filter and all is fine. Any one out there help?
