If the dishwasher is new, ensure the plastic "knockout plug" in the disposal inlet was removed.
If cleaning the filter doesn't solve the problem, the issue may lie in the drain hose. This is the flexible tube that connects the dishwasher to your sink drain or garbage disposal. Disconnect the hose from the disposal end and place it in a bucket. If water doesn't flow out freely, there is likely a kink or a clog inside the line. You can sometimes clear these by gently wringing the hose to break up solid masses or by blowing high-pressure air through the line. Ensure that the hose is installed with a "high loop" or connected to an air gap to prevent dirty sink water from backflowing into your dishwasher.
If you have one, remove the chrome cap. Underneath is a plastic hose elbow. Debris often shoots up here. unclogging dishwasher drain

I cleared the hose, but I wasn't taking chances. I reconnected the trap and the hose, tightening the clamps. But I knew from the gurgle that the main drain line might have buildup further down.
If water still isn't moving, the clog is downstream.
If your dishwasher drains into a disposal, run it for 30 seconds to clear any food that might be backing up the line. Disconnect the hose from the disposal end and
I went to the garage and retrieved the "big gun"—a 25-foot hand-crank drain snake (auger).
Ensure the one-way valve in the drain hose isn't stuck or installed backward.
