Interpreting beeps and lights in faults in diplomat adp 8352?

I have a diplomat adp 8352 dishwasher. It has developed a fault and beeps 10 times every minute or so. When the unit is opened, while it appears to have started a cycle, there is no water and the thee light from the left of the unit are lit. I have tried general maintenance including replenishing salt and general purpose clean when I actually got the unit to run. Can anyone help, I am pulling my hair out.
