Brown, white, red, blue, yellow. Let's say, for example, if I wanted to measure my voltage going... So let's go back over here. If I wanted to measure the voltage going to the, uh, to the pre-wash valve, just for the sake of argument, right? What you would do is you would place your multimeter leads between pins one and five, activate the pre-wash valve, and then you should see one hundred and twenty volts AC on your multimeter.

Now, for this, you have to have the connector attached to the board, right? That's very important. Otherwise, you're not gonna get anything. So this is, uh, kind of our first sort of, um, kind of our first lesson over here in troubleshooting in terms of being able to pinpoint the root cause of an issue. So let's say the bleach valve is what was causing an issue for, for your customer, right?

Just, just for the sake of argument. Well, you would need to activate that bleach valve in order to be able to see that, that voltage. Either that or you could just swap it out, swap out the main and the, and the valves, but we don't wanna do that. So in order to activate the bleach valve, there is a service mode you can get into, right?

You can turn the jog dial, press a series of key code sequences, and then eventually go into service mode and activate the test that would activate the bleach valve. But that can make it a little bit difficult if you don't know how to get into the service mode and, uh, maybe you don't have the s- the tech sheet, things like that.

So that's why I wanna go ahead and show you very quickly how you can leverage SmartHQ Service, and we're gonna go ahead and show that right now. So here we have the, uh, SmartHQ Service application connected to a, uh, to a front load washer. And if I wanted to actually go into the test mode and just turn on the, the water valve, right?

This-- in particular, the bleach valve, I would go into... Let me go back over here to show you. I would go into Diagnostic Features. Then we would press Operate Loads. And, uh, obviously, we would have to enter service mode. We're not gonna do that right now, but, uh, let's go ahead and select Pump. And then when we enter...

Not Pump, sorry, Water Valves. We're in the Water Valves over here. We're already there. You can see right here that we have our, our valves, every single one. And if I enter service mode and activate... So if I was to enter service mode right here. So let's go ahead and do it anyway. It doesn't matter. So we enter service mode, and then we activate the bleach valve, turn it on.

That should make it so that there's voltage going to the valve itself. And now with your multimeter, you should be able to measure that, uh, a hundred and twenty volts AC, which makes it very, very easy for you to determine whether or not you have voltage going to that valve or not.
