how can I fix my diplomat adp8332 dishwasher?

Help! Diplomat dishwasher adp8332 gone wrong,beeps & F4 comes up after started on a 50 degree wash cycle,no water left in bottom, but If set on a 65 or 70 degree cycle, it stops working & clicking sound heard instead of beeping & water left in bottom. When opened, the light for rinse cyle is illuminated even though a different prog was selected!
