Common Causes and Fixes of GE Nautilus Dishwasher Not Draining

Common Causes and Fixes of GE Nautilus Dishwasher Not Draining

Before diagnosing the problems, you need to do a few preliminary checks

  • First off, have a look at the drain hose. Make sure it’s not twisted or blocked. 
  • Next, check where the dishwasher drains. If it is linked to a garbage disposal, see if that’s all clear. Sometimes, gunk can build up there and mess things up. 
  • Lastly, if the dishwasher is new, ensure the garbage disposal’s drain tube doesn’t have this plug that needs to be removed.

1. Check Air Gap and High Loop

It must be in good condition if your dishwasher drains into a sink’s air gap or through a high loop underneath it. 

The air gap is a little device generally located next to your sink—it stops water from flowing the wrong way. Sometimes, it can get clogged with debris, so remove the cover and cap to clean it out.

The high loop is different but does a similar job. It makes sure the water is going one way—down. Check if the drain hose is looped up high under the sink, like a little U-turn. If not, water might be sneaking back where it shouldn’t.

2. Check Filter and Sump

Check Filter and Sump Nautilus Dishwasher

The dishwasher’s filter and the sump are the real cleaners, ensuring things stay clean and tidy.

The filter hangs out in the lower part of your dishwasher. It filters out food scraps and other debris. If your model has a removable filter, take it out and give it a good clean with hot, soapy water. Get rid of any gunk that’s hanging around.

The sump is like the big boss of the dishwasher. It’s the bathtub at the bottom that holds all the water.

Make sure it does not contain any big bits of meat or debris. Cleaning it regularly prevents blockages and allows the dishwasher to drain nicely.

Remember, safety comes first. Before doing this, make sure to unplug the dishwasher.

3. Examine the Drain Hose

The drain hose must work properly and safely for the dishwasher to drain. 

First, check to see if it is twisted up. A bent hose may be a big reason for the dishwasher that won’t drain. Straighten it out if you spot any twists.

Next, if the hose seems okay, but your dishwasher still isn’t draining, you should test for blockages. Disconnect the hose and see if something’s clogging it up. Sometimes, gunk or bits of food can build up, causing a traffic jam for the water.

If you have a drain snake tool, you can use it to clean out any stubborn blockages. Otherwise, detach the hose and run a quick cycle with the end in a big bucket.

That may flush out the blockage. Keep an eye out for spills—when checking the hose, things could get a bit moist.

4. Check the Drain Pump GE Nautilus Dishwasher

The drain pump is the powerhouse responsible for sending all that dirty water out of your dishwasher. 

To clean it: First, give the pump a visual check. You need to check if the impeller, the part that helps move the water, is all good. Try giving it a gentle turn. If it doesn’t budge or feels broken, that‘s the issue.

Now, for a more technical check, you’ll need a multimeter. Test the drain pump for continuity. You need to see if there is a smooth electrical path. Without continuity, it might be time to get a new pump. 

How you get to the pump depends on the dishwasher version. You may need to remove the bottom panel or get entry to it from the dishwasher.

But remember, safety comes first—cut the electricity and turn off the water before you start poking around.
