SOURCE: DISHWASHER WON'T DRAIN WATER
This needs to be investigate properly. Let me provide you with all the steps you need to follow ;-
Water-inlet valve Most cleaning problems are caused by the dishwasher not getting enough wash water, so the water-inlet valve is often to blame. This valve is usually at the bottom left or right of the dishwasher, behind the lower access panel. It's the device with the main water line from the house, a rubber tube to the dishwasher, and two wires attached to it.
When a water-inlet valve is defective, you may hear the sound that's usually referred to as "water hammer." If the water-inlet valve is defective, you need to completely replace it.
Dishwasher Water Inlet Valve Replacement
Be sure to read and understand any instructions that come with the new water inlet valve.
Step 1. Disconnect the dishwasher from its power source.
Note: Dishwashers are usually wired directly to the home’s electrical system. To disconnect the power, switch off the circuit breaker or remove the fuse for the electrical circuit the dishwasher is attached to. Try to turn the unit on after disconnecting the power to be sure you were successful.
CAUTION: If you’re not sure you’ve shut off the power properly, DO NOT CONTINUE. Call a qualified appliance repair technician to complete the repair.
Step 2. Turn off the water supply to the dishwasher. This is usually underneath the kitchen sink or in the basement or crawlspace near the location of the dishwasher. Pliers may be helpful here.
Note: If there are no shut-off valves, you must shut the water off at the main water supply valve for your home.
Step 3. Remove the lower panel(s) of the dishwasher. These are usually held by 2 to 4 screws at the upper and lower corners of the panel(s).
The inlet valve is usually near the front of the dishwasher. Attached to the valve you’ll see: 2 or 4 wires, the water supply line from the house and the water feed line that goes to the dishwasher.
Step 4. Remove the household water supply line from the valve. The line is usually secured with a brass compression nut. The water supply line is usually copper or braided stainless steel.
CAUTION: Water supply line may be hot.
Step 5. Remove the fitting from the valve the water supply line was attached to. This fitting may be very difficult to remove. It may help to put the valve into a vice in order to remove the fitting. If you cannot remove it, replace it. The fitting is not an appliance part but a plumbing part that is available at most hardware stores.
Step 6. Remove the screws holding the valve to the dishwasher frame.
Step 7. Label the wires to the valve so you’ll be sure to reattach them correctly.
Step 8. Remove the wires from the valve.
Step 9. Remove the clamp on the black rubber water discharge tube and pull the tube off of the valve.
Step 10. Reinstall the old fitting (or a replacement fitting if necessary) onto the new valve the water supply line was attached to. Use Teflon tape or pipe joint compound as a thread sealant. Make this fitting tight to prevent leaks. Make sure that the fitting points in the same direction as the old one so that the water supply line will meet up with it properly.
Step 11. Install the new valve in the reverse order of the removal instructions.
Note: The water supply line is under high pressure. Be sure to tighten the fittings properly.
Step 12. Turn on the water to the machine, and check for and correct any leaks.
Step 13. Reinstall the access panel(s). Restore the power to the dishwasher and test.
Note: You may have to let the dishwasher run a few minutes before it reaches the next water fill cycle.
Internal filters Every dishwasher has some type of filter to keep large food particles and foreign objects away from the pump assembly:
Drain valve Some dishwashers have a valve (or gate) that should open only during draining. If debris lodges in the valve, it can't close properly, so water drains out during the wash cycle. Most dishwashers drain into the garbage disposer. If yours does that, listen for water flowing into the disposer during the wash cycle. If you can hear it then, the drain valve may be clogged.
Spray arms There's a spray arm at the bottom of your dishwasher--it may have a tall spray tube mounted to the center of it. There may also be a spray arm located directly beneath the upper rack of dishes and/or above the upper rack.
If debris is blocking the holes in the spray arms where the water comes out, it could cause cleaning problems. Regularly inspect each of the spray arms and clean out the holes as necessary.
Water temperature To get the best cleaning results, the water entering your dishwasher needs to be hot enough. Try running the hot water in your kitchen sink for about 30 seconds before starting the dishwasher, to pre-heat it. Also, if your dishwasher lets you select a higher wash or rinse temperature, try that to see if it helps.
To check the temperature of the hot water that comes from your kitchen faucet use a waterproof thermometer. If the water isn't 120 degrees Fahrenheit, your dishwasher may have trouble getting your dishes clean. You could increase the temperature of the hot water to the whole house--and therefore the dishwasher--by adjusting the hot water heater thermostat.
Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.
Detergent cup Dishwashers don't perform their best if detergent is introduced only at the beginning of a cycle, so add detergent to both parts of the cup.
If the detergent cup isn't opening, see the "The detergent cup doesn't open" section, below.
Hope i helped you.

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.

The airgap prevents the water from the sink backflowing into the dishwasher. You could espically if your dishwasher hasa corragated plastic drain hose attach it under the sink so at one point the hose is higher that the nozzle of the disposer it connects to so the hose is still higher that the level of the nozzle and water wont backfill into the dishwasher.

SOURCE: My dishwasher air gap leaks.
Hi and welcome to FixYa, I am Kelly.
This is most often caused by the following:
- The diverter plate undet the plastic nut of the Air gap still has debris in it.
- The exit port in the air gap having debris in it.
- The **** connection port (often a garbage disposal) is partially clogged.
Take the air gap apart.
- Pull off the decorative cap by pulling straight up
( NOTE The postion of the nut and internal diverter plate as it can only be installed in one place )
- Unscrew the plastic nut
- Lift off nut and diverter plate
- Use a flashlight to inspect DEEP to the exit port of the Air Gap (Clean if \needed)
Once clean re-install the diverterplate in the correct position and screw in the nut. Slide decorative cover over the Air Gap.
Next PULL off the sink connection drian hose at the sink connection. Clean the sink port connection. It is usually 5/8" to 3/4" in diameter. If the Air gap is clean this is usually where the restrictions are from a reduced hole size.
This should correct the problem. It is not your dishwasher that is causing the problem... it is the drain plumbing from the diverter plate of the air gap up to and THROUGH the sink connection port that is usually the garbage disposal port being restricted. This is where you need to concentrate your efforts. When these are clean your Air-Gap will stop leaking.
You might even have to pull the hose off the outlet side of the Air gap and check for debris that you could not see with the flashlight.
Thanks for choosing FixYa,
