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.
To steps it says to use special function menu mentions button I do not have.
I tried asking AI, and it mentioned holding left arrow plus right arrow, then turning to changing on, and clean should flash multiple LEDs.
Delicate wash flashes and express wash stays lit when doing this. Then pressing start lights both those LEDs. Then press start again, I can hear something clicking twice, then the active and clean LEDs flash including delicate and express wash.
And if I try doing a normal wash. Some thing but the sanitise light flashes. And no water this time
The buttons aren’t labeled on the front of your machine as A B or C. But A is the button furthest to the left, B is the middle button, and C is the button on the right. Post a pic of the front of the machine with the controls or post the make and model.
Hmmm, looks like the tech sheet you have is for a dishwasher that has a 3 digit 7 segment display. Odd that it would have the wrong sheet. This looks like thee correct version for your model, follow the steps that say for shx (the first part of your model number).
Oh thank you. I understand better now.
The active and clean light are flashing which the others person shared from their diagram that it could be to drain pump.

This might be the LED to service modes that can apply to yours.

I THINK this is for your model
Those two flashing complains about the drain pump. Another comment I saw showed the drain pump cover not being pressed down all the way until it clicks in can cause it.

I can’t find the actual repair manual for that model though to decode the menu options for the service mode. Another similar display less model probably has the same meanings for the flashing LED lights. Their UI is atrocious.
