Water comes out through our air gap (vent)

When our dishwasher drains, water is coming out through our air vent on the sink top. Looks like I probably need to clean something -- connection to the disposal, something else? Help!

I have a Kenmore quiet guard 3 model: 665.74364k2 and serie F55202295. It is not draining properly. It works fine and cleans the dishes but when it goes to drain it leaks in my basement ceiling and vents.


if you have an air gap vent in the kitchen sink plumbing then make sure it is clear. Also looks like the kitchen drain end is blocked. Pour some caustic soda into the sink drain, wait 10 minutes and run water into the sink.

If you are using insinkerator (garbage disposer) in sink, make sure it is run before you start the dishwasher.

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...


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

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.

Water is coming out of air flow gap. I installed a new air-flow gap and all new lines from air flow gap to sink (except the line from dishwasher to air flow gap) and i still have water coming out the air...


The leak in an air gap is usually caused by a clogged sink discharge line. Most of the time this is connected to the garbage disposal and there is food particulate in the drain hole where the dishwasher drain from the air gap to the garbage disposal connects.

Pull the sink connection hose off and clean the hole thoroughly. You can try testing the dishwasher/ air gap by placing the disconnected hose into a bucket during the pump out period. It should not leak. After this test...reconnect the hose to the sink connection.

If it is NOT connected to the garbage disposal then remove the hose and clean out the hole where the connection is made. This is a common problem and easily resolved by the user.

Thanks for using FixYa.

Bosch dishwasher SHU4000 problem starting, not draining


Drain problems are almost always going to be a clog. Disconnect the drain hose from the air gap vent at the sink top. Place a bucket under the hose and run the drain cycle. Unit should drain. If not, clog is either in drain hose or under the dishwasher's internal filter. Remove filter. Locate the item causing the clog and remove it. If nothing is found here, the problem will be in the air vent gap filter itself. Disconnect the other hose and remove the air vent gap from the sink. There's a small cap at the top of the filter. Press the clips in to remove the cap. Flush the unit with water or use a thin, long blade screwdriver to remove the debris.

Put it all back together and test again. You should be fine.

2in.of water standing in bottom when finished


Most likely a clog, either along the drain hose, or more likely, actually in the air gap vent. Disconnect the drain hose from the dishwasher and place a bucket under it. Run the drain cycle. This should clear any clog along the drain line. Remove the air gap vent from the top of the sink and disconnect the other hose. Remove the small cap at the top of the vent by pressing the small clips on opposite sides of each other and lift the cap out. Using either a strong flow of water, or, a thin, long-blade screwdriver, remove any debris from the two hose connectors. (Problem is most likely in the smaller hose connector which is preventing water from flowing over to the other connector to drain out). So, during operation, water goes up the small drain hose, but can't go any further and water remains in the dishwasher.

Clearing the air vent cap/filter should solve your problem.

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

Water in bottom will not drain, checked air vent..., it;s clear


HI. check the following areas for faults.

1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

Dishwasher doesn't drain completely after full cycle


If there is any blockage in your diposal, water will comes up to the sink, since it happened to me. As soon I installed the air gap then it fixed the problem. No air gap, water flowing is slowing down conflicting with timed draining causing this problem. Let's think of this, if you fill up water in a 1/2 galon milk container, and you try to emty it. If you pull down straightly , it will be slow compared to pull it at an agle to let air going into the opening. The air vent helps water flow better meeting the timed draining.
