Thanks, Sam: So does the board provide voltage to lets say wires A and B, postive and negative. Then to reverse it provides power to C and D postive and Negative?

Is this correct.
Thanks,
Sal

After watching the video on testing a BLDC motor by using a 9 Volt Battery and my question is, why do you have 2 positive wires? Why not the 12 volt supply voltage and Ground? Is it the PWM?
Thanks,

Thank you for such nice words. You guys are great and just plain nice people.

Thank you,

Lastly, why did you pull the unit out to test? Could you have made the tests from the board in front? Eeps? Please help because i am trying to better understand dishwashers

Thank you Sam

Thank you for the response back, I did not charge a diagnostic fee but I will from now on. And your right at times misdiagnosis problems may happen and I would have to eat that cost.

Thank you,

Makes perfect sense, I feel I am ready, just a bit nervous about taking apart the appliances. I don’t want to be embarrassed should I stumble. But for theory and troubleshooting, I am confident that I am ready. And you guys are always available via appliantology should I need help.

Thank you,

I think this follow up is important for students. But i decided to read the manual not only the schematic and found that fan kicks on after 6 minutes. I completely missed that and fan works fine. As we are taught here at samaurai tech is to be thourough. We are techs and that means to be prepared before and during a service call i learned my lesson.
Thank you again samaurai tech.

So just to finalize this discussion, so if voltage at drain motor but it does not work, bad drain motor. If not getting voltage to drain motor in diagnostic mode, then I can conclude the board is bad?

Am I on the right track?

Thanks Sam, and nice to meet you.

Thank you, I am glad you cleared that up for me. So I quess depending on the person, asking for help could be a good thing. I am a member of Appliantology and it is a great site.

Thank you again,

Great advice: You are truly a master at what you do. The reason I asked about this is because a couple of years ago my wife called a service tech to repair our washing machine. And while trouble shooting he asked my wife to push the switch on the door while he made some measurements. I DO NOT WANT TO EVER HAVE TO HAVE A CUSTOMER HELP WITH A SERVICE CALL. Am I correct in saying this?

Thank you,
Sal

Excellent, now last question and I think I can comfortably say that I have this. Example, Washer not running.

Cam number 1 needs to be closed in order to power the entire system. So I decide to check the cam and see it is closed, I measure O volts, this is telling me that it is closed and I am just reading one side of a closed switch to the other. If it were open then I would read 120 volts and can conclude that the Cam is bad and I can replace timer. But could I test continuity on the Cam switch just to make sure? If I am correct on all this, I think I am ready.

Thank you for your patience.

One last thought, so if I am using my loading meter and I read 120 Volts can I then make the assumption that the valve is bad?

Thanks Again
Sal

[Salvatore Frisina]

So if I have 0 volts, what does that mean? I will assume since it is a loading meter I have an open neutral or bad voltage. Is this correct?

Please help!

[Salvatore Frisina]

Thank you, Very helpful as usual.

Just to chime in, I had problems with this one. I understand how to calculate resistance in parallel circuits, but I don’t know if the resistance for two components were given. Please explain.

Thanks,
