Re: water drains to drain air gap on sink
From your description, it sounds like the line going into your drain system ( through the garbage disposal or directly into your drain itself) may be restricting water flow.. A quick test would be to detach your drain hose and cycle an empty dishwasher but run the drain water into a rubber barrel so as to eliminate your drain system from being the root cause. If it doesn't drain correctly into a barrell, then you may have a clogged filter or an something in the pump ( including but not necessarily the problem.. a bad pump) Try this test and let me know what happens..

I ran into the SAME problem with my Bosch SHX46A06UC /21. The problem ultimately ended up being a clog in the air gap vent, (meaning, SOMEBODY ran the dishwasher without the bottom filter being in place or not in place properly). Remove the air gap cover and upper surface nut to drop the air gap vent into the area under the sink. Disconnect the hoses from the air gap vent filter (placing a bucket under the hose from the dishwasher). Run the drain cycle on the dishwasher. The washer should drain into the bucket and let you know that your pump works and that there are no clogs or kinks in the drain hose. (This will also remove the clog if so). The air gap vent's smaller hose connection is MOST LIKELY where your clog is. Look at the upper end of the air gap vent. You'll see a couple of clips on opposite sides of each other, that hold the air vent cap in place. Using a small screwdriver, (or your hands if you can), depress the clips (or one at a time) to get to the point where you can pull the vent cap off the filter. Either use water or a thin, long blade screwdriver to force any objects out of the filter. You should now have full flow through both branches of the filter. Using water and a rag, clean the vent cap and filter. Mount the air gap vent filter back onto the sink. Reconnect the hoses and remove the dishwasher's internal filter(s) and clean them as well while you're at it, making sure to remove any debris that might remain underneath the filter and has the chance of clogging the unit again.
We really need your model number to help you properly. In the mean time you can check you sink connection and air gap for obstructions. Usually the cover just pulls up and off then you unscrew the cap to expose the drain tube for the dishwasher. More often than not if the unit fills and washes but leave soap on the dishes a clogged drain line is the problem. You may have to run something down the drain tube to clear it. Usually you will see the obstruction when you remove the cap. There is a remote possibility if it drains into a garbage disposal that food particles have clogged the drain outlet inside the garbage disposal. Hope this resolves your problems. Cheers!
The drain hose is supposed to go from the garbage disposal to a high point under the sink in back to keep the water from gravity draining into the dishwasher when it shuts off. If you look you will see that the hose is laying on the bottom of the sink cabinet. Get a hook and wire it up so you're not washing dishes with water from the disposer. Be sure to run the disposer. if it is clogged with food the dishwasher will not drain, water will back up and drain back into the dishwasher. Also make sure that the pipe exiting the disposer isn't clogged and draining slowly. hhe best solution is to have an air gap that mounts on the sink. It goes between the washer and the disposer to keep this from happening.
1. Unscrew air gap which is on the counter-top next to sink. 2. Unscrew drain clamp under the sink which s connected to the air gap. 3. Use a wire hanger to push down debris clogging the drain. 4. Screw clamp and air gap back in place. 5. The dishwasher should work. Routinely clean out air gap every half year.
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

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.

By the airlock , you mean the air gap? .If the water is coming out of you air gap that means the hose that connects the air gap to your drain is clogged or your drain itself is clogged.Check the hose that connect the air gap to your drain(or disposer), check air gap and clogged disposer opening
