My 4 year old frigidaire dishwasher won't run....I had this issue before and it seemed that unplugging then plugging it back in did the trick. Now, when I unplug it the "heated dry" and "hi-temp wash" lights flash, indicating a power failure. I press "start/cancel" per the service data sheet then I can select my wash cycle. When I press start again nothing happens. The wash cycle light goes out and then, nothing. Any thoughts? Thanks in advance for your help.

The first thing I would do is check if the door switches are properly engaged when the door is latched. The model number you posted is incomplete.
