Diplomat ADP8352 does not complete cycle?

I have an 18 month old integrated Diplomat ADP8352 dishwasher which stops part way through a wash cycle. When it stops it beeps twice and when I open the door there are no fault code lights and the power to the whole display panel appears to have cut out as none of the panel lights will illuminate, even the on/off power button. If the machine is left for a while (certainly after 30 minutes), power at the panel and indication lights are restored and it is possible to set on a cycle again, however the same fault repeats but not always at the same point in the cycle, as sometimes it still has water in it. Any ideas?


Thanks
