Dishwasher Not Draining | How to Fix a Dishwasher That Won’t Drain in 4 Steps

A dishwasher filter screens out large food particles to prevent them from clogging the drain pump or hose. Over time, the filter itself can become clogged with debris and block water from draining. Fortunately, cleaning the filter can be a simple solution when your Frigidaire dishwasher wont drain. Most dishwasher cleaning tips recommend monthly filter cleanings to prevent blockages.

Heres how to clean a Frigidaire dishwasher drain filter:

  • Remove the dishwashers bottom rack.
  • Press down on the wash arm while rotating the filter handle counterclockwise.
  • Pull up the spray arm to remove it with the filter.
  • Reconnect the spray arm and filter and place it back in its compartment.
  • Rotate the filter handle clockwise and press down on the spray arm to lock it in place.

Check The Drain Valve Operation

If the valve appears to be fully closed or fully open, check the drain valves operation by re-attaching the wires. Take great care with this step. Plug the dishwasher into the outlet and have someone select the drain cycle on the control panel. You should be able to see or hear the drain valve open or close.

If the drain valve doesnt operate, install a new drain valve. Re-attach the wires and hoses in the reverse of the removal you did earlier.

Why Is Our Brand New Dishwasher Not Draining

So, some background on this issue first… our old dishwasher seemed to work fine when we first moved into this house, but within the last year it started having a drainage issue. Water would be left standing in the bottom of the dishwasher after the cycle finished which was leading to yucky stuff down there as well. My husband pulled the dishwasher out, unplugged the drain hose, made sure the trap was clean, etc. Unfortunately, the problem was not solved.

Finally, we just got a brand new dishwasher hoping that our drainage problem was behind us, but sadly the new dishwasher doesn’t drain either! HELP! All that I can see is a black drain hose which goes down into our crawl space and then back up and attaches to our sink. The sink has not had any drainage problems. Any ideas?

  • 4What happens if you put water into the drain pipe without the dishwasher installed. Does it drain?

You say that the drain hose runs down to the crawlspace then back up again. It’s winter time I wonder if the water is freezing in the drain hose at the lowest point, enough that hot water from the dishwasher isn’t able to reach it to melt it .

I think it’s odd that the drain hose feeds through the crawlspace any installations that I can remember seeing have a hose feeding through the cabinet wall to the sink’s plumbing. Is the dishwasher adjacent to the sink so that you could redirect the hose like that?

Your drain line could be clogged.

Check The Dishwasher Filter

  • After youve checked the plumbing, check inside the dishwasher along the bottom of the tub for food and waste buildup. Clean the area with a rag or abrasive sponge.
  • Check the filter. It will be located at the back or along the bottom of the tub near the spray arm. New units have smaller grids that are built into the base. These are designed to protect the filter from buildup, but sometimes debris can still accumulate.
  • Use a screwdriver to unscrew the casing. Remove the filter and clean it as needed.

    How To Diagnose Plumbing

    Surprisingly often, drain problems with a dishwasher originate in drain parts outside the appliance itself. Not all the following steps will need to be completed. Continue until you determine the cause of the dishwasher’s drainage problems. If none of these plumbing-related issues seem to be at fault, then proceed to the diagnosing issues with the dishwasher itself.

    Air Gap And Garbage Disposal Problems

    Sometimes, a Frigidaire dishwasher not draining water is due to an air gap or garbage disposal clog and not a dishwasher issue. If you have an air gap or garbage disposal, they likely share a common drain with the dishwasher. When either device becomes blocked with debris, it can clog this shared drain. Water will then backflow into the dishwasher during a wash cycle.

    Running the disposal before starting a wash cycle can clear the drain of debris that can block water flow. Air gaps can be easily cleaned by opening the cap and removing any visible debris with a paper towel or nylon bristle brush.

    Listen To It During Operation

    Run your dishwasher through a normal cycle and listen for anything unusual. If it is making grinding sounds or seems to be struggling more than normal, you may need to replace the drain pump and motor. When the drain pump and other components go bad, the machine will usually start making a humming or clicking noise, which will make it ineffective and prevent it from draining properly. Call a plumber when this occurs.

    Reset the cycle

    Though this was probably the first thing you tried, go ahead and try again to be sure it wont work. Try hitting the cancel or reset button. If the dishwasher was interrupted in the middle of the cycle, it might not know what to do with all of the extra water. If there isnt a visible button for canceling the cycle, look in your instruction manual, as there may be a series of buttons you have to push.

    There should be an easy-to-find reset button that comes in handy if you accidentally interrupted the appliance mid-cycle.

    Check If The Waste Hose Is Blocked

    If cleaning the filters doesnt fix the problem, check that the waste hose at the back of the dishwasher isnt squashed or kinked if it is, this could stop the waste water from draining away.

    If you have a freestanding machine, you and one other person will be able to pull it away from the wall. You can then check that there’s enough room for the hose to drain properly.
