Tip & How-To about Dishwashers

Quickest way to fix a drain issue on a dishwasher

Have you ever noticed water coming out of the top of your sink from the Air-Gap? I have had many service calls where people have had that issues for years and didn't think it was a problem. The purpose of the air-gap is to be an over flow in case your disposal hose gets clogged and a quick clean out.
Please check your air gap at least once a month to be sure there is not any food stuck in the hose. A good percentage of your drain issues will start at the air gap and it could be the only problem. Here are some instructions on how to clean out your air-gap:

  1. Remove the cover
  2. Remove the cap (Some have 2x clips that have to be pinched others have a cap you pull off)
  3. Check the smaller tube it should have a little water and if you see any food debris etc.. clean it out
  4. Replace the cap
Replace the cover and test by running a quick cycle. Another suggestion would be to clean out the disposal tube once a year of any sludge buildup.
Wow you fixed it!

bad smell coming from bottom - water doesn't completely drain out


Make sure the drain hose is not blocked or pinched.Also check where it drains into your sink pipeing to be sure food isnt blocking the drain way.
Its eather the drainage path is blocked or the pump stoped pumping.
Also, the drain hose must be installed so as to have a high spot higher than the sink drain or the water from your sink will be able to "run down hill" or drain into your dishwasher. Take a look and see!

also It sounds like your dishwasher does not have an air gap. Newer dishwashers come with an air gap installed, but they can be taken out. A quick fix for this is to:

Check the drain line under the kitchen sink. The drain line is supposed to run from the bottom of the cabinet, and run as high in the cabinet as you can get, (up to the bottom of the counter top) then connect the drain. This is called an air gap, and helps keep a little water in the drain line, which will prevent sewer gases from entering your dishwasher, and garbage disposal.

There are two hoses coming from my Bosch SHE45M06UC dishwasher. One is obviously the drain coming from the back of the unit, and the other is attached to the side looped and not connected to anything. I went online to the Bosch website for a installation manual and it describes this hose as a air venting hose. Does the end attach anywhere or does it just hang loose on the unit. My husband detached it from its original position and thought it was part of the water line. HELP!


Many people realize the dishwasher connects to a little hose on the sink, it is called an air gap. However, many people wonder " The air gap is there to prevent the water from being siphoned out of the dishwasher. When water flows through the drain hose, it creates a suction on the water still in the dishwasher. The air gap, makes a hole for air to get in. That way, the water only leaves the dishwasher when it supposed to, when it is pumped out. Another benefit of an air gap is that if the drain hose becomes clogged, the dishwasher can still pump out the water. Instead of flowing through the hose, as it should, it can flow out the air gap and into the sink.
The dishwasher's drain line usually connects to an air gap mounted at the countertop level on the sink. The drain line continues from the air gap to either the garbage disposer or directly to the sink drain. If the drainage hose between the air gap and the drain is partially or completely blocked, wat

I get water all over my counter when dishwasher gets rid of water. There is a feature on my sink of which water comes out. This just started...


Since this just started, I would suggest cleaning out the p-trap under your sink. If your sink drains sluggishly without a pump, then your dishwasher will overflow your drain pipes with its pump.
Also, try facing any air gap opening into the sink.
If the pipes are clear, you may need to add a length of pipe between the air gap on the sink and the 'y' connector that the drain lines are connected to. This will help keep any splashing water from 'climbing' out of the sink-top vent. Good luck

Does Not Drain ... We Don't even Use it


I know you're probably not needing this anymore, but for anyone else who has a similar problem...

Your dishwasher is installed wrong. You should never get water back into it from washing dishes in the sink. (of course - unless it is installed wrong) The "drain air gap" that you should see on top of your sink is to prevent water from back-flowing into your dishwasher. Sometimes plumbers put in a "stand pipe" (a pipe that goes way up in your sink cabinet underneath, but just is actually the pipe from the dishwasher and they loop it up higher than the bottom of the sink level in the cabinet. That way if you see water in your sink, most likely you can figure out why it is backed up before it gets higher than the stand pipe and goes into your dishwasher. Since you don't see the air gap device on top of the sink then I'm guessing whoever installed your dishwasher either put in a stand pipe and didn't put it up high enough, or more likely didn't put one in at all and therefore you are getting back-flow into the dishwasher.

3. Use a wire hanger to push down debris clogging the drain.
4. Screw clamp and air gap back in place.
