Water discharging from Air Gap onto counter

I have cleaned the drain, garbage disposal, hose from air gap to garbage disposal and air gap. When dishwasher drains, it flows into garbage disposal from the air gap and drains properly. The garbage disposal does not fill up to the inlet with the drainage water. Everything appears normal until the just about the end of the drainage cycle then it stops flowing into the garbage disposal and the dishwasher water starts coming out the air gap all over the counter. It is almost like the dishwasher drain motor reverses. Does the dishwasher drain motor need to be replaced or does something else need to be done?

It looks like you have a clogh in waist pipeline somewhere in house. When drainage water coming it has much less flow than the dishwaser drains. To check it you need to put in a sink large amount of water at once (several cans to reach the same volume you have in dishwasher). If water stays you have a clog.
If everything is fine it is air gap problem. Some of them have a tendensy spit and cough water out.
Good Luck

They are intended to prevent back siphoning but you can do the same with a high loop in the drain hose. Run the drain out of the washer all the way to just under the counter and strap it to the cabinet, then to your disposal. The problem you are experiencing should not happen but we don't know if you added a new washer or who did your plumbing. Somethings is causing a partial blockage, you did not accidently reverse the two hoses did you? The drain from the machine goes to the smaller of the two tubes of the air gap.

You need to replace motor .

Before that confirm connections are proper . Any short circuit inside the unit can cause this problem . You need to check continuity of circuit .

Check all the gaskets, and also check the water level switch.
I can give you more details if you provide model number.

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.

It dosn't discherge the water


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/control sector
Replace if defective (note: uncommon problem).

Once my dishwasher completed the cycle there is no water but after two or three days the bottom of the dishwasher fills with the dirty water. what could be the reason? I have garbage disposal and one pipe...


You must have your dishwasher connected directly to the garbage disposal and not through an air gap. What is happening is when you disposal fills with water it is siphoning through the drain hose back to the dishwasher. If you sink has a spare hole on the deck install air gap and run dishwasher drain through air gap first. Otherwise make sure you run Garbage disposal often so that water does not get slowed and build up inside.

The part by the sink causes water to flow all over the counter


Almost all dishwashers connect to the sink drain in one way or another. Many connect (via an Air Gap valve) to a garbage disposal.
If the "metal part" is at the rear of the sink, that is the top of the air gap. When water comes out of it, that means the drain is plugged.
If there is a garbage disposal, does water drain through it? Does the disposal work?
If there is no disposal, does water from the faucet run through the drain of each sink with no problem?
Thanks for answering these questions in a reply.

Dishwasher does not drain completely, has standing water after every complete cycle.


  • Some water, usually one to two cups, remaining in the bottom of the tub is normal. However, if water is covering the bottom of the tub, the dishwasher is not draining properly.

  • Check for paper or large objects covering or blocking the sump area in the rear of the tub.

  • Make sure that the right type and amount of detergent is used: Using the wrong type or too much detergent can cause sudsing that can prevent the dishwasher from draining. Only detergent specifically designed for automatic dishwashers such as Electrasol®, Cascade® or Cascade Complete® should be used. If you find suds in the dishwasher.

  • Check disposer plug. If a garbage disposer has been recently installed, it is possible the disposer drain plug was not removed. The drain plug is a plastic piece in the disposer that blocks the hole where the dishwasher hose connects.

    Please consult the Owner's Manual. Download a free copy of the Owners Manual and/or Installation Instructions. In the Installation Instructions, will be the procedure for removal of the drain plug. You may also check with the installer.


  • Be sure the kitchen sink drain is not clogged. The dishwasher typically drains into the kitchen sink drain or a garbage disposer. If the dishwasher drains into a garbage disposer, run the disposer to clear the drain system. Do not put hands into the garbage disposer. Serious injury could result. You should always turn on your garbage disposer prior to running the dishwasher to clean out any food or debris within the drain system.

  • Check drain hose where it connects below the sink for blockage or a kink in the hose. New dishwashers come with a white corrugated drain hose, which should be used. Re-using old, worn out drain hoses may promote kinking and blockage. If it is neccessary to extend the length of the corrugated drain hose, be sure the total length does not exceed 120 inches and the extention used is not kinked or crushed. See your dishwasher installation instructions for details.

  • Check the air gap if one is installed. It could be clogged. An air gap (not part of the dishwasher) is usually located on top of the sink. Some state or local plumbing codes require the use of an air gap between the built-in dishwasher and the drain system of the home. This plumbing device is used to prevent the possibility of back flow into the dishwasher in the event of a clogged drain system. This item is not a part of the dishwasher and, therefore, the dishwasher warranty does not cover costs related to cleaning or repairing a drain air gap.

  • Typical air gaps are easy to inspect and clean. Be sure the dishwasher latch is in the OFF position or unlatched prior to removal of the drain air gap cover. Simply lift off the cover (usually chrome, could plastic) and unscrew or unsnap (depending on type of air gap) the plastic cap below. Remove any material that may have accumulated and replace the plastic cap and chrome cover. This simple procedure should be followed any time the dishwasher fails to drain properly.

    Sometimes perceived "no drain" problems are not "no drain" problems at all, but back flow of water from the sink or some other device into the dishwasher:

  • If you notice dirty water building up over time in the bottom of the dishwasher and do not have an air gap, make sure you have a high drain loop. A high drain loop is created when the drain hose is makes a loop at least 18 inches above the floor. Usually this is accomplished by attaching the drain hose to the underside of the countertop. Without a high drain loop or air gap, dirty water from the sink can flow into the dishwasher. The high drain loop prevents back flow of water from the drain into the dishwasher if an air gap is not installed. View a short video about a high drain loop:
