PISTON VALVE

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.

DRAIN SOLENOID

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 the timer as well.

CHECK VALVE

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 (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.

DRAIN PUMP

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.

DRAIN HOSE

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.

Clogged or Improperly Installed Garbage Disposer

If the dishwasher won't drain and the garbage disposer was installed recently, the installer might have forgotten to knock out the drain plug from this disposer. All garbage disposers are sold with a solid plug in the drain tube for situations where a dishwasher isn't connected. However, if the dishwasher is connected, the plug will need to be removed. If the disposer wasn't replaced recently, remove the dishwasher drain hose from the disposer and clean out both the fitting on the disposer and the end of the drain hose. These are the most common places to find an obstruction if the dishwasher won't drain.

If the dishwasher won't drain the check valve might be stuck closed. The check valve is a device which prevents water from returning to the dishwasher after it has drained.

Sometimes the check valve is accessed from the inside of the unit depending on the model.

Electrolux professional series not pumping water


Two things to consider....clean water or dirty water?

Clean water usually indicates the fill valve is not shutting off all the way and the fill valve is "weeping" water in all the time = new fill valve time!!

Dirty water usually is not a dishwasher problem but more of a plumbing issue. Often the sink drain that carries the sinks water outside is not fast enough and some of this sink water is backing up into the drain hose and filling up the dishwasher through the drain hose. The drain from the sink to outside needs attention as this type of a problem indicates a slow house drain for that sink.

The dishwasher drain line should be clamped to the top underneath part of the counter before entering the sink drain plumbing, this may help the water from coming back inside the dishwasher.

Hi

Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. Check the drain hose for any visible clogging, remove if present. If no visible lint is present then remove then turn off the dishwasher and remove the drain hose and check for any visible clogging. If still not visible then the drain filter or drain pump is clogged and you'll need to clean the drain filter and drain pump.
Please note that dishwashers don't drain out the complete water such that heating element doesn't overheat. Hope this helps... Please post back for any further assistance.
