When my ones lights flashed (lights 2 and 4) I thought it was def broken, i then discovered it was a knife in the top tray stopping the shower from spinning. worth a try- make sure its empty when you test it.

Hello. I really need the make/model number to help you accurately. However, from the symptoms you're describing, it sounds like the drain pump is jammed. A lot of dishwashers turn on the drain pump first to remove any stagnant water sitting in the bottom of the pump. Then, fresh water is let into the tub, fills to the proper amount, then the main pump starts. The lights flashing are an error code--different combinations of buttons flashing mean different things. On some models, a button light will flash a certain number of times, pause, then flash another number of times. This is a binary code telling the user what is malfunctioning. That's why I need the model number and any other info to help diagnose the issue. Thanks!
If your Dishwasher is not Draining check the following
On some dishwashers that have a filter (screen) along the back wall of the tub have a piston valve. The piston valve commonly causes dishwashers not to pump out. if your dishwasher does have a filter, remove it. Now remove the piston valve located in the center behind the filter. Now to check the piston valve, press up on the spring. Once done the piston should stop up the hole in the top of the valve. When a piston valve, is bad the piston dissolves to the point that it can no longer stop up the hole, in this case replace it.
Another common problem on some dishwashers that will cause it not to drain properly is the drain solenoid. To check this, first disconnect power from dishwasher then remove the bottom panel of dishwasher. Once off, you should see the drain solenoid attached to the main pump then reach under the dishwasher and push down on the solenoid. If it will not move down it is bad and needs replacing. If it will push, down most of the time it is good but not always so follow these steps as well. Reconnect power to dishwasher, now start the dishwasher in to a cycle. If you have a mechanical timer turn it slowly until the solenoid energizes. If you turn the timer all the way around and the solenoid never energizes replace the solenoid. If you have an electronic control, start the dishwasher and wait a few minutes then push start/reset then the drain solenoid should energizes, if not replace the solenoid. At times the timer will cause this part to go bad especially if its melted or frozen down. So you may have to replace timeras well.
If your dishwasher is not draining properly, the check valve may be your problem. The check valve will be on some dishwashers with both a separate drain pump or drain valve (note if you do not have both you will not have a check valve). The check valve will be located where the black hose connects to the drain pump. To access the check valve, you must first remove the water from the dishwasher. A Wet-Vac works well. After the water is out, disconnect power to dishwasher. Now remove the dishwasher from under the cabinet. Now remove the black hose (even though you removed the water you will still have water in the pump so be ready).Once off you should see the check valve. It's the little red rubber flap. If it is torn off, the flap may have gone down the drain but you still should see the red ring left behind, in this case replace the valve. Sometimes the check valve will swell up and hang in the pump, if so replace it.
If your dishwasher is not draining properly, the drain pump may be your problem. As stated before, not all dishwashers will have a drain pump. To check this, First check to see if it is getting power. You should have 120 volts when the dishwasher is put into a drain cycle. If you have power and the pump does not run remove the pump and check for obstructions if none found replace the pump.
If your dishwasher is not draining properly, the drain hose may be stopped up. To check, remove all the water from tub. A Wet-Vac works well for this. After the water is gone remove the drain hose (even though you removed the water you will still have water in the pump so be ready) from the house plumbing and the dishwasher. Check for obstructions and remove. If you just installed a new garbage disposal check that the metal knockout was removed. Check the air gap if this is not right your dishwasher will siphon water back into it.Use the VOM .God bless you
"First green light flashing"... that meant the float cut off switch which is right at the bottom of the machine, was being activated by a water leak filling up the bottom tray where the float switch lives. The water inlet valve was closed to prevent any more flooding, and green light No 1 shows "no water entering machine".
In some cases, the leak was due to a burst in the short black rubber hose between the main pump and the water trap under the main filter and drain assembly. Need a new hose cured the whole sorry mess. To get at the relevant bits turn machine on its side and remove the bottom tray (six screws, three each side.
The bottom "Y" 3 point hose at the bottom connected to main motor is of poor quality and does have 3 wire clamps. The hose does perforate and small pin hole causes water at the bottom to trigger the anti flood system with warning lights flashing and pump motor on ...
The arrow straight line meens end of program. However the flashing lights do indicate an error codeas per the handbook. This could be the ati flood device (polystireen float / micro switch) at the bottom of the machiene indicating a water leak. This device puts the washer in pump out mode and nothing els works until the error has been rectified.
holding the button for four seconds will not do it, you have to hold it until the light stops blinking and
will go back to normal, normall takes more than four seconds to unlock the unit, this is something
the sears repair techs know becouse the are trained on all this things but, they will not share this things, becouse thats how they make money
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.
