The linked video shows how to test a water valve to a washing machine. He starts by doing a continuity test on the valve and expects the circuit to be closed. He said an open circuit indicates a bad valve.

In my case, both my water valves have no continuity (thus open circuit, thus broken according to the youtuber). But if I simply attach 220v to the valves as suggested in this video, they both open and let water flow. So it seems there is no problem in that regard.

I don’t suppose he is testing incorrectly. He has lots of washer repair videos and seems to know what he is talking about. So why would my valves fail the continuity test yet function anyway? Is that cause for concern?

My actual problem that seems to be that the controller board is not sending the 220v to the valves despite the board being fed 220v just fine, so I kind of suspect the controller board – but I wonder if the controller board is doing a continuity test before sending the 220v, and refusing to send 220v to the valves because the circuit is open.

update

I am told it is very unlikely that a controller board would do a continuity test on the valves before sending 220V… that the extra sophistication would not pay off. I did a resistence test and that actually shows that there is continuity (@ ~4000 ohms). So apparently that’s just too much resistence for my meter’s continuity function to detect. Also unlikely that both valves would go bad at the same time. Looks like the controller board is bad.
