samsung d/w dw80r5060ug/aa0 issue

dishwasher comes on, fills with water and starts to wash. very soon, you hear a clicking on the board and the lights go off on the panel then comes back on after a second. continues to do this and will not do anything else. Sounds like a board issue to me but I have no schematic and have tried several of the methods online to put in service mode but no good. Anybody got info on this? TIA
