I saw a YouTube video where a guy tested the two pins with a multi-meter for continuous circuit and said if it reads it's ok but if it doesn't read the circuit is broken and the valve is faulty. I tested it on my washing machine but it didn't read so I bought a second hand one from eBay (the one in the pic) but this one is not reading either. Does that mean it's faulty too or are they not supposed to have a continuous connection between those two pins?

Depends what your meter is set for and are your leads actually touching the connections.

What you have is a coil of fine wire wrapped around umpteen hundred time on a "bobbin", so yes you should get a resistance reading of some sort.

The easy way to test them was to turn the water off on a washing machine, turn it to rinse, turn on the machine and listen for the valve humming, no hum = new valve required. But yes ideally it should be checked with a meter

The first pic is wires not touching, it reads 1. The second pic is wires touching, it reads 001. When I touch the connection pins on the valve nothing happens, it keeps reading 1.

Dead valve?

You have got the meter set to check diodes. That is not ideal, it should be set to check resistance.

OK, one click clockwise (to 200) and still nothing. Demanding a refund time?

add another click to the left (clock wise) if that coil has a higher than 200 Ohm resistance it will not show on 200 Ohms

One more click clockwise (to 2000) but still no change on the screen. It just reads 1.

in your case, 1 on the left means infinity, open circuit.

Does that mean there is a break in the coil of wire inside that valve?

Yes, a break in the wire, or a very bad connection. Either way you can't fix it. (generic one on ebay less than £6)

I tested the valves on my washing machine with the multi-meter. There was no reading with it set to 200 or 2000. But then I tried 20k and my hot water valve read about 4.15 and the cold water valves read a similar number. Then I tested the eBay valve with the 20k setting and there was nothing. It looks like my hot water valve is fine and the one off eBay is faulty?

Could it be that water pressure is too low for that valve? I have a gravity system here. If so are there valves that can work with low water pressure?

The coil should read anywhere between 500 - 1500 ohms yours are way too much. Did you disconnect the hot one while testing it?
