dishwasher won't drain ... at all.

Thinking the hose may be clogged, I disconnected the hose at the garbage disposer, and using a vacuum ... wet drytype, I was able to suck water out and hoped to release any clog. Didn't work. Then I tried to blow air backwards, and noticed it won't go backwards at all.

I hear the motor trying to pump water out, so I think it is working. Reading other answers, I noticed one solution is the drain solenoid ... which opens the valve so water can be pumped. Can you tell me .. if there is any type of ONE way valve in a Samsung dishwasher, preventing any water or air going backwards through the drain tube? IF a clog exists, jamming the pump internally, should I be able to clear it when I remove the drain? I am hoping to avoid buying a new pump if it is simply the drain solenoid. Let alone .... a new machine, LOL. Thanks in advance for your thoughts. CJB

Cause 1

Drain Pump

The drain pump uses an impeller to force water through the drain hose. If the drain pump motor is not working, the dishwasher won’t drain. To determine if the drain pump is defective, check the pump motor for continuity using a multimeter. If the motor does not have continuity, or if is getting power but won’t run, replace the drain pump. Drain pumps are not repairable—if the drain pump is defective, you must replace it.

Cause 2

Drain Impeller

The drain impeller pushes water through the drain hose and into the garbage disposer or drain line. If the impeller is broken, replace it.

Cause 3

Drain Solenoid Kit

The drain solenoid opens the drain valve to allow the water to exit the dishwasher. If the drain solenoid fails the valve will not open causing the dishwasher not to drain.
