NFT: Dishwasher not draining

ImThatGuy : 6/19/2017 2:09 pm

Just had some kitchen work done and now there is an inch of water in the dishwasher following a cycle. A new garbage disposal was installed and its possible the (lazy) contractors didn't pop out the plug properly and this is causing the backup so I will check that.

I also noticed the hose to the disposal feels like it has water in it now, is it possible that following a dishwasher cycle some of the residual water in the hose drained back into the dishwasher? If so how could I fix that? (note when i lift the hose a bit and see if gravity will take that water back into the dishwasher nothing happens?)

Anything else I can check for? Thanks in advance

Check the float in the diswasher

it is a switch that activates the pump. Sometimes that gets cruddy and needs to be cleaned. Also, check to make sure they installed the connection to the drain pipe properly. They Y should face up so the sink doesn't back flow into the washer.

Check the web for videos on all this. You can find a how to on just about anything on the web.

I would second that observation. I made the same mistake. Just attached the hose without popping out the plug.

BTW, the water in the drain line is to prevent sewer gas from leaking back in through the dishwasher, same as a j-trap.

If you had work

done and now the dishwasher doesn't work, the first thing you should do is call the contractor and tell him to get his ass over there and fix it.

Make sure the dishwasher hose

Is higher than where it leaves the dishwasher...tie it off to the faucet underneath the sink...sure fire way for it to back feed...

Does the hose go to an air gap then to the garbage disposal or does it directly go into the garbage disposal?

First thing to do

mavric : 6/19/2017 6:27 pm : link

is to check under the spinning propeller-like thingy to see if something is blocking the drain hole. Could be a piece of hot dog or hamburg or a piece of paper that came off a jar or something.

Reminds me of a joke:

How do you turn your dishwasher into a lawnmower? Tell her to get off her ass and mow the lawn!

Yes it is higher but the actual run to the disposal is now shorter so there is more slack then there previously was. Not sure what you mean by an air gap but it looks to go straight to disposal

If it goes right to the GD you don't have an air gap...

lono801 : 6/19/2017 8:46 pm : link

The air gap does the same thing as making sure the hose is as high as you can make it under the sink...Can you raise the hose higher?

In my travels...if the plug has not been removed from the GD...there will be a lot more water Inside the dishwasher than an inch.

When the dishwasher goes into drain mode...can you see or hear the water flowing into the GD? You should...

What make is it? Brand new?

Thanks lono & all

The plug was there so I knocked it out. Ran a 10 min rinse cycle and saw water flow thru garbage disposal hose. Will run a full load this evening but I think we are good

Just divorce her...
