Dishwasher drain solenoid or pump

our GE dishwasher (model gsd4030z07ww) stopped draining yesterday. The inside areas are not clogged just some tiny particles floating under the cover. The drain hose into the garbage disposal was fairly clogged (at the disposal)so cleaned it out. Also the drain hose comes in near top of sink so that requirement is met. Still won't drain.

I can get new solenoid for $17, pump for $90, or new dishwasher for $250. Is there a quick way to test solenoid and pump before spending money on parts?

Thanks in advance!

Test to see if power is getting to the solenoid &/or pump. If not, jump it. If it runs, then the pump is good.

I just took the front cover off. I am able to move the solenoid plunger so I ran a rinse cycle. The solenoid does activate and pull down. Also I can see the pump motor is spinning... So if they are both working.... What else could be wrong?

The solenoid activation is a good first step.
Did you remove the drain hose from the pump and look into the sump for a clog. I use a mirror as there isn't a lot of room underneath the unit.
Some units have a check valve that can become stuck closed.

Do you have a strong spray inside the unit when washing ?

In the parts list for your unit I see that it does have the check valve. I left a link below that shows the part. It's in the back of the tub. The link has a replacement video that shows detail of the valve.

Thank you Pete, I will take a look at the check valve this evening, what dies thus do anyway? I thought the water drained from the deep area in the tub more to the front/middle.

It seems to clean well, but we get most of the crud off before we put dishes in the washer.

The check valve allows air into the valve assembly for proper drainage.

Thank you so much! The check valve is caked with hard water deposits. I was able to free it up and Ran cycle which drained into the disposal. Ordered a new one for about $8, much better than buying a new machine. Thanks again PJmax!
