Part of trying the get my dishwasher to drain https://piefed.ca/c/diy@slrpnk.net/p/894317/help-fixing-my-dishwasher-it-won-t-drain-and-is-stop-on-sanitize-mode
I have removed to drain pump, solenoid, water heater.
The drain pump white part spins with no obstruction at all.
With a multimeter:
My solenoid is about to get 984 OHMs resistance.
I'm not sure how to check my drain pump. I don't see any connector end. Closest thing are these 6 metal spike thing pointed out on the motherboard.
I don't see any visible blockage.
I'm not sure if I need to check the voltage as well. And I'm not sure if i need the dishwasher running with water to test. Problem is still stuff is located at the bottom of the dishwasher. If I wanted to check the voltage with running water.
I bet it's the back flow valve. Mine would try draining for a few seconds then error. Repeated rinse cycles would drain a little at a time. It's past the pump in the out hose
Like the end with the white hose here?
Mine looks like this:

It's between the pump outflow and the drain hose. It didn't look bad on mine but replacing it worked
