I have a Frigidaire Dishwasher (PLDB998AC1). The wash selector panel will light up correctly, but when you press start it doesn't turn on and within about 5 seconds the lights on the selector panel go out.

Make sure the water feed is open....although I don't know this make and model, a flashing light at the start of a program is usually always to do with a water feed problem....make sure there is sufficient water pressure at the hose (by closing the tap, removing the feed from the dishwasher and opening tap with hose in bucket) You will be surprised how many times a worn tap washer is to blame for low pressure. A stiff turning tap is always a sure sign of problems.... If the unit is a integrated model, make sure that when you close the door it "clicks"...if it does not activate the door switch properly, there could be a flashing light. Sometimes the integrated units "move" deeper into the enclosure, and the door will not close properly to activate the door switch. Oshie

I'm not sure what combination of these steps fixed the problem but its fixed none the less.

As mentioned above i removed the screws at the top of the door removed the top cover. I disconnected the power connector (white) and reconnected. I removed the latch assembly cycled the latch a few times pushed the connectors on the bottom snuggly on. Reassembled the top and the replaced the screws.

After closing the door...all the lights were blinking?? No No its ok..

Place the dial on rinse only and press dry and start/cancel. This will place the dishwasher in a maintenance mode. It will cycle through all the cycles in a short amount of time.

After all of that it started up just fine. Like i said I'm not sure what part of this process made this all work I'm just putting it all out there and i hope it helps someone else with the same problem...

Try running the hot water in your kitchen sink until the dishwasher kicks on.

1) Turn off the breaker to the machine.

2) Wait 30 seconds and then turn it back on.

3) All the lights will be flashing. At this point turn the dial to "rinse only" and then press "Heat dry" and "Start/Cancel" at the same time.

4) The Machine will go into maintenance mode going through all the cycles quickly.

5) After this is finished the problem should be solved.
