The drian could be plugged or the pump could have an obstruction. Did you just install a garbage disposer? If you did you may need to knock out the plug in the disposer. Hope this helps

SOURCE: drain pump and no water going in

This most likely is not a level switch problem. Take the kick plate off (after turning circuit breaker OFF), look down in the base off the dw and youll probably see some water. Use a wet vac or towel to remove all water. The drain pump will now shut off and unit should function normally. You can now run the dw with the kick plate off and using a flashlight look for leaks. The bosch dw has a float switch in the base, water will activate this switch which will shut off the water valve and only allow the drain pump to run....it thinks it has a leak!
Make sure the disposal is draining properly & drain hose is not kinked as these are the most common reasons for your problem.

SOURCE: drain pump won't stop

that usually happens when there is water in the base of the dishwasher where the motors are. Check to see if there is water in the base. This will trigger a float that turns off the water and on the drain pump.Remove the water and it should fill. However note that water came from somewhere, so find where it is leaking.

SOURCE: dishwasher runs, water doesn't drain out

sounds to me that you may have some suds residue in the dishwasher that keeps it from draining completely. Get you some dishwasher cleaner which you can purchase at wal-mart or wherever you buy your detergent, and clean out your dishwasher. It is a inexpensive test. Alot less expensive than having a tech come to your house. Make sure that your drain hose is mounted higher that where it goes into the drain. This is also a common problem that I encounter in the field. Hope this helps. Let me know if I can help you futher.

SOURCE: Pump Runs On After Water Is All Drained Out?

If the cycle does not stop draining that is usually because of a faulty water level switch that controls the water level in your appliance.
The faulty sensor cause the machine to think that there is still water inside, even when water has drained completely.
Check if the floating sensor is stuck or faulty.
Some machine may use a membrane switch instead of a floater.

SOURCE: Kenmore portable dishwasher not draining

Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.

Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.

Drain valve and/or solenoid Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.

Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing.

Belt One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.

Motor If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced.

Some dishwashers are susceptible to getting stuck if you don't run them regularly. If you haven't run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can't be serviced.

My dishwasher won't drain properly. The pump has been making a weird sound for a month or so and last night it couldn't drain. It starting beeping and the pump was running. I cleaned the drain filter


If the pump is running but noisy then that indicates a loose pump impeller (new pump I am afraid) if running (no noise) but failing to remove water, then I would be checking that drain hose is clear, or even that your machine is not syphoning water from waste disposal, a quick check would be to disconnect waste hose from waste disposal and see if it will then drain into a bucket, hope this is helpful.

see this causes and proceed according. God bless you
Belt, Water Pump Although few dishwashers have a water pump belt, if the dishwasher won't drain there might be a worn or broken water pump belt. After removing the lower kick panel the motor can be seen in the front, the water pump belt is on the bottom of the motor.

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.

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 If the dishwasher won't drain, 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. The drain valve is not repairable Pump and Motor Assembly If the dishwasher won't drain, the pump and motor assembly might be defective. If the motor runs during the drain cycle, check for a blockage in the drain line. If the motor won't run during the drain cycle or if it just hums when it should be running, the pump and motor assembly might 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 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.

Check Valve If the dishwasher won't drain 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 If the dishwasher won't drain 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.

My dishwasher didn't drain the water out on the end of the clicle? What could be the problem?


Hello, Thank You for using FixYa. I will be helping you today.I would start where your drain line connects to the house drain,This is where most blocked drains happen. Disconnect the drain line and put it in a bucket and try to drain the dishwasher. Chances are its blocked somewhere you just have to find it.

Bosch dishwasher has water in bottom after cycle is complete


Hi

Kindly check for the following :

Check for hose kinks or food plugging drain hose. Start at the drain port exit.
Check the check valve and drain hose for debris.
Check pump motor for reversing during the pump out make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle.
Check pump motor assembly for a drain solenoid, during the pump out make sure the solenoid makes that distinctive "clunk" noise
If you have recently installed a new garbage disposal, check knock-out plug at connection.

Check pump impeller for damage.
Check that the water inlet valve isn't seeping fresh water into the dishwasher when off.

Please contact for any further clarifications.

Water standing in Dishwasher


Hello buzzy220,
If you have water remaining in the bottom of your dishwasher then I would check the following:
  1. The drain filter screen is free from food byproducts that might limit drainage.
  2. The drain line exiting the dishwasher itself.. is it kinked or clogged?
  3. If your drain line is plumbed into a garbage disposal side entry, is that clogged or your house drain clogged?
  4. Is your dishwasher pump contaminated with sediment or anything that would limit its ability to pump?
  5. Are the water lines that come into or out of the pump blocked, damaged or restricting water flow?
Those are the main reasons areas of concern to investigate.. BTW, your drain line exitting the dishwasher should be routed up high and down into your sink drain system or thru the garbage disposal tap so that you have an air gap as 20YRSEXP was inquiring about..

You can run a simple test to verify all this..
Detach your drain hose from the house drain system ( from the garbage disposer or sink drain.. then route that into a rubber barrel ( be sure to keep part of the house up around the height of the countertop when you do this.. )... You should see a fairly robust flow of drain water into it when the system functions properly.. I would encourage you to run this test with no dishes inside it,.. This test will tell you if the restriction is in the dishwasher or house drain side..
Hope this helps you..
Regards,
Rick

Miele dishwasher g664 12 years old maybe?


Hi Lawrenceo,

I'm Harvey the Master Plumber.

You stated your problem as: the dishwasher won't drain.....can here a valve opening and gurgling but then no water exiting. Have cleaned everything and pushed water via tap back through water-exit hose.I to have a Miele G664 dishwasher and when turned on no water no fill. Just sits there with a moter running. Un able to get anyone to come and have a look at it as I live in Mount Victoria NSW.
It sounds like the pump has failed. The motor and the pump are two different parts. This is a common problem with older units. Frankly, after 12 years of use, at least you got your money's worth. At this age, to repair it is to throw good money after bad. It's time o replace it. You'll find there are much nicer models available now.

Feel free contact me again!
