Here is a prior identical question with response FYI:

VERY easy to do yourself with simple tools in most cases - and generally unless you broke it with a pot or such, may just need the top popped off and a twisted paper towel or such run down into the hoses to clear any clog.

The hoses are usually just attached with screwdrive hose clamps (simple screwdriver removal) or spring-type hose clamps (pliers or channel lock removal), then the air gap is attached wither with screws under the sink, or with a locknut under the countertop. One of the simplest home repair fixes.

If your problem is discharge line clogging, in addition to the air gap, a common place is where the drain hose connects to the garbage disposal (a very common but lousy place to connect it) because the barb it fits over fits up inside the hose, blocking food particles passing through and causing a blockage. Undo hose clamp (be prepared, even if sink is empty as it has to be, for a bit of dirty water to come out - maybe up to a cup or two), wiggle the hose off, clean out the barb on the dishwasher and also the inside of the hose using a long handled brush or twisted up paper towel (though that commonly will just push the debris further up into the hose) or a straightened out coathanger wire into the hose end. Usually the clog is only an inch or so into the hose so even a large screwdriver or dull table knife can work it out.
