which light flashes?

SOURCE: Whirlpool ADP951 Dishwasher

Processor board sound bad. May be a loose plug ( or corroded connection on the plug ) . Unplug the dish washer from the wall plug before servicing. The open the front panel to expose the panel control board. Unplug the panel plugs and inspect them to assure no corrotion is apparent. If you see corrotion, use a pencil erracer to clean all contact points on the board and clean the plug the best possible. Plug the dishwasher plug back in the wall and check the unit for proper operation. If the operation is not correct, replace the circuit board. I hope this helps

the first thing that your dishwasher does when you turn it on is drain when you turn it on you hear a motor running then it stops then it fills start the washer when it stops to start filling open the door should be no water in the unit if there is you have a drain problem and in fact are washing your dishes in dirty water can be several things that can cause drain problems a piece of food blocking the line at the sink where the drain goes in if its run to a disposer there is a knockout plug that should be removed just stick your finger in there to see if it was removed get you installation instructions and read the part about not removing the drain loop but just about all the time installers will lol if you cant find the instructions go to www.frigidaire.com under customer support can down load them there let me know what you find

You need the control panel to reset before anything else can happen. To do this TURN OFF THE PLUG SOCKET FIRST AND UNPLUG. Then you need to drain ALL the water from the machine. Turn off the water supply feed and place the wastage pipe as low to the floor as poss ( 1-2" off floor). Water will gush out so use a large shallow tray and keep emptying the tray. Tilt the dishwasher over slightly to make sure all the water is out.
This will allow the control panel to reset itself which wouldn't normally happen if the base of the dishwasher was holding even a small amount of water.
Re connect the water, plug back in , select the RESET setting on the dial and close the door and switch on.
Leave for about 20 seconds and then turn off.
Rotate the selector switch to "A" Intensive wash and switch
I found this on another site and it really did work for me

Indesit IDL700 first two green lights flashing and cycle stops with dirty water left in the machine. CAUSE - blocked or jammed drain pump. SOLUTION - First remove all the filters inside the machine, syphon or sponge up all the water in the sump and check for any obstruction over the fine grill at the very bottom. (we had a pistachio shell covering the hole!). If this doesn't cue it you will need to gain access to the pump. First, turn off the power. Gently lift the machine onto it's side (be ready for some water to spill out!). Remove the bottom plate (6 screws) and disconnect the sump float switch. Remove the single screw retaining the pump to the bottom of the machine and rotate to remove. You should be able to see the rotor blades. With your finger check to see if the pump rotates freely. To dismantle the pump, remove the 3 screws and separate the two halves. Our pump was jammed with an apple stalk!. Reassemble and connect any cables. Apparently this is a known problem with these machines and can be prevented by assembling the filter system correctly and pre-rinsing plates etc. before placing in the dishwasher.
