Common Causes Of A Clogged Drain

GE Dishwasher Drain Pump Replacement #WD35X20875

The most common causes of a dishwasher not draining are food and cleaning products. These can clog the drain and cause it to stop working. Most are plumbed into a garbage disposal, so make sure that is not plugged as well. If the drain pump motor is bad you would be able to NOT hear it as it drains. Excess dirty dishes, with too much food debris, is the normal cause for not draining. The corrugated drain hose tends to collect these particles and clog the line. Make sure you also check the dishwasher filter as well, a commonly overlooked item.

  • Unattach the mounting brackets so you can pull the dishwasher out from under the counter to access the bottom.
  • Lay the unit on its back
  • Remove the wiring harnesses from the drain solenoid and the other from the motor
  • Loosen the clamp that goes to the sump, and also the outlet for the pump to the center spray nozzle
  • Remove the clamp on the drain return line. Be sure to keep a container or towel near, as there will probably be water in this hose.
  • Remove the support clamp for the motor

    The function of a drain pump in a dishwasher is to remove water from the tub after each wash cycle. The pump is usually located near the bottom of the dishwasher and is connected to the drain hose. Over time, the pump may become clogged with dirt and debris, or it may simply wear out from regular use. If the pump is not working properly, water will not be able to drain from the dishwasher and it will need to be replaced.

    There are a few signs that indicate a problem with the drain pump, such as water accumulating in the tub after a wash cycle, dishes that are not getting clean, or strange noises coming from the dishwasher.

    If you notice any of these issues, its best to call a qualified technician to diagnose the problem and replace the pump if necessary. Or, if youre DIY-minded, you can replace the drain pump yourself!

    It can be a tricky repair to tackle on your own, but with this step-by-step guide, youll be able to do it in no time! Keep in mind that before you begin this project, you will need some basic tools and supplies. So gather up what you need and lets get started!

    Note: Before replacing the drain pump, which can be costly, make sure that the filters are clear of any debris. Often, this is the problem and simply clearing the filters will fix the issue. If not, then you can move on to replacing the pump. But by checking the filters first, you could save yourself both time and money.

    Chopper Blade Area Clogged With Food

    The chopper blade in a dishwasher is designed to dice items removed from the dishes into small particles before being drained.

    This process helps avoid a clogged sink and dishwasher line. If too much debris builds up around the chopper screen, the dishwasher can stop draining.

    When this occurs your best option is to check the chopper blade for damages, and clean all debris out of the area. If the blade is damaged, youll need to replace it. Heres how to do that:

  • Disconnect the power
  • Open the door and remove the lower and upper rack from the dishwasher. Set both racks aside
  • Remove the retaining nut from the lower spray arm
  • Lift the spray arm off
  • Find the spring clips on each side of the spray tower thats attached to the back wall of the washtub
  • Press the clips to release the tower
  • Release the lower spray arm bearing and lift it from the center of the tub
  • Remove the screws holding the filter housing and pump cover in place
