My Kenmore Ultra Wash III dishwasher 665.1584990 will not drain. Checked drain hose at both ends and disposal opening and no clog. Pulled check valve and no clog. When running cancel/drain function sounds like working but will not drain manually. What can I check next?

It could be an obstruction in the drain hose (most common), or in the air-break (if you have one), or at the check valve, or something may be blocking or stopping the drain pump impeller. Try this: Close the door and press Cancel. (Or if your dishwasher has the controls that are hidden under your counter ledge when you close the door, then press Cancel first and then close the door. Do you hear anything? Is the drain pump trying to run? If so, then start at your garbage disposal and work backwards. If you got a new garbage disposal installed, make sure that you (or the installer) remembered to knock out the hard-plastic plug at the end of the dishwasher connector port. Also make sure you don't have a clog right there. If that's okay, then check the drain hose (or air-break, if you have one) for clogs. If that's okay, then you will probably want to call a professional because the next steps involve removing and dismantling the drain pump.

If the dishwasher won't drain, the drain pump might be defective. Test the pump motor with an Ohm meter. Drain pumps are not repairable, if it's defective it will need to be replaced.
HERE ARE SOME OTHER COMMON CAUSES:
H Drain impeller. The drain impeller is attached to the pump and pushes the water out of the dishwasher through the drain tube and into the garbage disposer or drain line. If the dishwasher won't drain, the drain impeller might be broken or worn out. Replace both the impeller and seal at the same time.
Drain Solenoid Kit. The drain solenoid kit might need to be replaced. The drain solenoid is an actuator that opens a flap to allow the water to drain.
Drain Valve. The drain valve can get clogged with debris and should be cleaned out if the dishwasher won't drain. If it seems clear of debris but won't actuate, it will need to be replaced.
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 needs 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.
Check Valve. The check valve might be stuck closed. The check valve is a small plastic device which prevents water from returning to the dishwasher after it has drained. If the valve gets stuck closed, it will prevent the water from draining. The check valve is the device that the drain hose is attached to on the dishwasher.
Check Ball. The check ball might be stuck. The check ball is a small plastic ball in the check valve which prevents water from returning to the dishwasher after it has drained. If the ball gets stuck, it will prevent the water from draining also. The check valve is the device that the drain hose is attached to on the dishwasher.

First, check the dishwasher filter and make sure it isn't clogged. Your owner's manual will have simple instructions on how to access and clean your dishwasher's filter.

Next, check the drain hose. Does it look flattened or kinked? Do you see any sharp bends? If so, straighten out the hose with your hands and manipulate it so that it regains its rounded shape.

If your dishwasher drains through the garbage disposal, try running the garbage disposal for a bit to process and clear any food. If that does not get the machine draining, you may have a deeper clog. However, most drain hoses clog either at the main household sink drain line connection or the garbage disposal connection.

Does your dishwasher spray your dishes, but it does not advance to the next stage and drain the dirty water? The timer controls the start of the draining process, so you may need an entirely new timer or a new motor for the timer. Repair service is recommended.

In some dishwashers, standing water is caused by a valve that fails to open and allow the water to drain out. This valve is controlled a solenoid that the timer controls. A malfunctioning solenoid could be the problem.

either the check valve on the end of the drain hose that connects to the drainpump motor is closed shut or sometin is clogged inside the drain hose..... also maybe you pump motor assmbly is faulty... u prob need wet/dryshop vac and drain it out from inside then check that hose... hope this helps... possibly may need to replace that drain hose,,, prob not worth reparing if its a pump motor depending on which brand some had 5 yr part warranties on the pump motor assembly

Hi

Thanks for using FixYa. Dishwasher not draining properly or not draining at all issues can arise due to different reasons. Usually, these issues are related to kinked hoses, knocked out disposer unit (if connected with the dishwasher drain hose) & clogged drain pump & filter.

Also note that dishwashers do not drain completely after a finished cycle and this is normal. Dishwashers are designed to leave some water in the unit to ensure that the heating element doesn’t overheat. If you suddenly begin to experience a large amount of water being retained in your dishwasher, you have a problem. Some of the most common reasons include that the drain hose isn’t working properly, the drain pump isn’t working correctly, or possibly there is a plumbing problem in your home’s drain lines.



First check whether the drain is not clogged or blocked and the line is not kinked. Check all the hoses for blockages & also clean the air gap. Has the disposer been replaced recently? If so, chances are the knockout is still in place. Simply remove the drain hose from the disposer, and knock out the plug. If the disposer has not been replaced, try removing the drain hose from the disposer and use a wet-dry vacuum (prepared for water, of course) to **** any water (and hopefully anything else) from the drain line. Then reconnect the hose, and test the unit. If you have checked the air gap and the drain hose and can’t locate the problem, then it is an issue with the drain pump of the dishwasher.

Please do rate the solution and revert for further assistance.

HI.This is a drain issue. check the following areas for faults.

1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

Ok, if the hoses are ok and not clogged, this will confirm a major issue that concerns the drain assembly or pump impeller.

replace the pump(drain) if found to be faulty.

Fixerfailure, is the knock-out plug still inside if the garbage disposal inlet?

Stick a screwdriver in there to make sure.

spazmo1969, could be the rubber flapper is broken off in the pump discharge outlet.

From the sound of things, your dishwasher drains faster than your sink drain ( via the garbage disposal) can drain it off.. You may have a problem with the way your sink drain/trap is vented and there is too much back pressure to drain down quickly.. When you run water from your sink, does it take a long time to drain down or if you fill your sink up and drain it, does it drain slowly ? That may be your problem.. Hope that helps.

Some Kenmore DW have a check valve attached to the sump that may have a blockage. Remove toe panel, look for a long, white, plastic fitting attached the front, right side of the sump. Remove the drain hose from the valve. Unscrew the valve from the sump and inspect for debris inside the valve.
