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 do I need the dishwasher running for that. Problem is still stuff is located at the bottom of the dishwasher.
Water inlet valve here shows 990-995 Ohms
As I suspected this has your resistance measurements for each of the motors, so measure where indicated (power disconected) and you can see if the windings in the motor is faulty. Your selonoid value looks good.
