Remove Standing Water From The Dishwasher

Now you’ll want to remove all the water from your dishwasher. It’s important to lay down towels around the base to absorb any spillage, especially if you have a lot of water at the bottom.

You can use towels to absorb the water or use a plastic cup to scoop it up and place it into a bucket. If there’s plenty of water and you want to speed up the process, you can also use a wet/dry vacuum for this step.

Dishwasher Drain Pump: How To Test

my dishwasher isn’t draining.

I checked the drain hose and it’s clear enough that I could blow air through it.

  • I removed the drain pump, model #W10158351B I measured the resistancebetween the two connector pins: ~24ohms.
  • I connected the two leads toa 120VAC supply. The impeller would turn maybe 2-3 degrees and stop,with the motor making a hum. I did this with the polarity only oneway .

I think this is pretty conclusive that the motor is dead but I’d like to be sure before I buy the replacement.

I’m also surprised to find water has been leaking out of the pump bit by bit. I presume that means water has made it past the impeller seal and is generally bad?

Is my drain pump bad? Are there other tests I should perform?


  • It did. There was some resistance, but not a ton.

I have the same problem you had. I am not sure of the proper impedance you should have. One internet repair place says 200 ohms for a good motor. I did the same thing you did lines were clear to disposal – I also exercised the check valve which is in the 90 degree black elbow right off the drain pump on my machine forward and backward to ensure it flowed and would stop flow in the reverse direction, which it did. I do not have leads that are compatible with the motor to check that it runs. I am going to replace the drain pump to see if that is the problem. Also, the jerky motion on the impeller is due to the magnetism on the motor.

For future reference, before you take the thing out:

Check The Drain Solenoid Kit

GE Dishwasher Drain Pump, Fits Brand GE, Hotpoint, Kenmore

If you still havent found the cause of your GE dishwasher not draining, the next component to check is the drain solenoid. The solenoid opens the drain valve so that water can drain out of the dishwasher.

To check if it is faulty:

  • Locate the drain solenoid.
  • Check for any obvious signs of damage.
  • If it is damaged, replace it. If it is not damaged, youll next need to check the drain valve.

    How To Fix A Ge Dishwasher Not Draining

    A dishwasher that cannot drain is a problem you will want to get fixed quickly. Not only is there a risk of further damage caused by leaking water, but dirty dishes will also start piling up in the sink. Fortunately, this guide is here to help you.

    Most of the time, the dishwasher will not be draining because of a defective drain pump. However, before you access the drain pump, check that the drain hose is connected properly and not blocked. The filter and sump should also be checked for debris. If the dishwasher still will not drain, there may be a defective solenoid causing the issue.

    Go through the checks below to diagnose and fix the drainage issue in your GE dishwasher.

    This guide applies to most GE dishwasher models, including the following:



    How To Diagnose Dishwasher Problems

    If you have a dishwasher that is not running or is not cleaning your dishes as well as it used to, there are likely some problems you can diagnose and fix.

  • Check for a blown fuse or tripped circuit breaker.
  • Check that the dishwasher is plugged in securely.
  • Inspect the wiring connection to the dishwasher for burns or breaks.
  • Check the door latch.

    Check The Drain Valve

    If the drain valve gets clogged up, water wont be able to flow through it properly.

    To make sure water can flow through it:

  • Locate the drain valve.
  • Check to see if it is clogged up.
  • If it is clogged up, clean it out and then test to see if this has solved the problem.
  • If it isnt clogged up, check if it is operating correctly when you try to drain the dishwasher. If it isnt working at all, it will need to be replaced, as it cannot be repaired. However, if it is working, then it probably isnt the cause of the dishwasher not draining, so you can move on to checking the next component.
  • How To Test A Dishwasher Pump Motor

    GE Dishwasher Drain Pump Not Draining Repair / Motor Replacement GDF520PSF4SS

    Have you ever loaded the dishwasher and expected clean dishes only to discover that nothing happened? Well, your dishwasher may have a faulty pump motor. Whether it be looking for error codes or using a multimeter, lets take a look at how you can identify a bad pump motor.

    When youre trying to get your dishes clean, nothing will get under your skin quite as bad as a dishwasher that doesnt want to work. If youve already gone through a portion of the troubleshooting, chances are that youre going to want to make sure that the dishwasher pump motor isnt at fault. But, how do you test that motor out without making a serious mess?

    Before you even think of testing anything, check to see if your dishwasher posts an error code relating to the pump motor. If not, check for symptoms of a bad pump motor. If you still need more evidence of a bad motor, use a hook volt multimeter to read the resistance of the motor. A good motor will only have 30 to 40 ohms of resistance.

    Trying to manually test a dishwasher pump motor is not always necessary if you know what else you can look for. This guide will help you troubleshoot that dishwasher and hopefully figure out your next steps.

    How Do You Reset A Ge Dishwasher

    GE dishwasher models come with a “Start/Reset” button, so all you have to do is press and hold this button for a few seconds, then wait two minutes for it to reset.

    If this doesn’t solve the issue you’re experiencing with your appliance you may need to perform a hard reset. To do this, cut off the power supply to the dishwasher by turning off the circuit breaker connected to it. Wait 30 seconds, then turn it back on.

    Not Filling With Water

    The GE dishwasher may not fill up with water appropriately because of a faulty fill hose or an obstruction on the hose. However, this condition can also happen due to a leaky faucet or broken water pipe.

    To troubleshoot this issue, follow these steps:

    1. First, turn off the power and remove the access panel. Remove the screws that hold the fill tube in place on the dishwasher.

    2. Remove the fill tube by unscrewing it from the dishwasher.

    3. Check the fill tube to see if any obstructions or debris could prevent the water from flowing properly. Clear the obstacles and check leaks in the water supply and the faucet.

    4. If everything looks OK, turn the water back on and test your dishwasher to see if it has filled up with water.

    5. If it doesnt resolve, call the GE service center.

    Check The Garbage Disposal

    If your dishwasher is connected to the garbage disposal and it has recently been installed, the drain plug that is in it may not have been removed, and this will stop water from being able to drain. However, if your dishwasher isnt connected to the garbage disposal, then the drain plug must be kept in place.

    So, if your dishwasher is connected to the garbage disposal you need to:

  • Make sure that the drain plug has been removed.
  • Disconnect the drain hose from the garbage disposer and then give the fitting on the disposer and the drain hose a good clean. This should ensure that water can drain out properly.
  • Reattach the drain hose and then turn your dishwasher on to see if the problem has been solved.

    Check The Drain Impeller

    The first component to check is the drain impeller. The drain impeller can sometimes break, and water is then not able to be pushed out through the drain hose into the garbage disposal or drain line.

    To check it:

  • Inspect it for any signs of damage.
  • If damaged, replace it. If it is fine, move on to checking the next component.
  • Clogged Drain Hose Under The Sink

    If theres a clog in the drain hose, the water will only run through the hose when the dishwasher door is open. To clear this clog, use a plunger to push the blockage into the drain pipe. Then, turn off the power supply to the dishwasher and wait until the water drains completely before turning the power back on.

    Damaged Drain Pump Impeller

    The drain pump on your GE dishwasher uses an impeller to push water through the drain hose and down into the drain tube. A damaged impeller will cause water to pool at the bottom of your dishwasher.

    In some GE dishwasher models, you can replace an impeller independently. Find out how to do this by watching this video:

    Other models will require you to replace the entire drain pump if the impeller malfunctions.

    It’s also important to check if the drain pump itself is malfunctioning as this can also prevent your GE dishwasher from draining properly.

    Use a multimeter to perform a continuity test on your drain pump. If it shows a reading of 200 ohms, then it’s not the problem. If it fails to show any reading, then you’ll need to replace it.

    Cause # : Blocked Filter

    The second most commonly reported reason is the blocked filter. Food particles clog the filter that can block the drainage system.

    Solution: Clean the water filter periodically to ensure that it stays in mint condition. Some GE dishwashers come with ultra-fine and fine filters.

    Follow the steps below to clean the water filter in your GE dishwasher.

    To clean the ultra-fine filter

    • Remove the bottom rack to access the water filter.
    • Twist the ultra-fine filter counterclockwise and lift to remove it.
    • Rinse the filter with warm soapy water and use a sponge to carefully remove any stuck food particles. Dont scrub with scouring pads and toothbrushes, as it can damage the ultra-fine filter.
    • To remove any stains or smells, you can also dip the filter in white vinegar for 10-20 minutes.
    • Insert the filter back in its place and twist it clockwise to lock it in its place.
    • Make sure you check the arrow on the fine filter. It must be used as a guide to align the placement of an ultra-fine filter. It is a great idea to take a picture before removing the ultra-fine filter.

    To clean the fine filter

    Please note that 1-2 cups of water covering the bottom of the tub is normal on models without an ultra-fine filter in GE dishwashers. In models with an ultra-fine filter, water in the sump is normal, but the water should not cover the bottom of the tub.

    Cause # : Garbage Disposal Problems

    A newly installed garbage disposal can be the reason behind your GE dishwasher not draining. The drain plug may not have been removed, or a blockage in the garbage disposal can be causing draining problems.

    Solution: Check garbage disposal under the sink and ensure that no valves are in the closed position. If you cant figure out whats wrong with it, call a licensed technician for inspection.
