How do you test a washing machine control board?

Washing machine does not work. Since it just bought one years ago, the components in it is not old, I think. So I want to check it from its PCB. Any tips on this?

It is a good way to fully test a modern appliance circuit board by connecting it up to a checked and fully functioning appliance the same as it came from. Even the manufacturers repair guys’ test boards that way if they have the same dilemma.
You can also visually check all of the solder joints and connectors and test the components that can be tested with a meter (resistors, capacitors and traces).
Contact the suppliers for after-sales service if it is within the warranty period.

Which soldering iron tip should I use?

All of the soldering I’ve done to this point has been with through-hole components. I hope to move up to some smaller surface-mount parts at some point in the future. I’ve got a Weller WES51 soldering station. There is a large number of ET series tips available. How do I choose the right tip for the components I’ll be working with?

What is the use of thermal reliefs on vias for a copper pour?

My EDA software (PCAD, but I guess others do this too) adds thermal reliefs on vias in a copper pour. What’s the use? Vias aren’t soldered.

Is paste mask layer, both top and bottom layer, necessary for THT components?

I know the paste mask layer is also called the stencil layer. It’s only used for assembly. I want to know if the paste mask layer (both top and bottom layer) is necessary for through hole components. For SMD components I know the paste mask layer is required to solder the components. Is it necessary for through hole components?
