my kenwood 243a?

Hi, My dishwasher has decided to play up. I opened the dooor the other day to add something to the wash in mid cycle( something I have done umpteen tmies before & my electric tripped. When i tried to restart the dishwasher I found that it wont reprogramme. It showed the alarm for "salt & rinse aid" - these have been dealt with but it still wont programme to restart.
ANY IDEAS???? Thanks
