washing machine control board mistake

hi, pardon if this isnt the best place to post this question,
i bought a used washer locally, was told the lid lock switch needed replaced,
in a attempt to cheap out on the cost of the part, i opened things up and started (randonly) bypassing (shorting?) wires (3) leading up to said switch.
at one point something fried in the control board, and upon inspection, is was (i think) a sense resistor leading up to a capacitor (i think). it was cooked enough that it was nowhere to be seen, and my solution was to short that as well and find out what would happen.
now i know it hasnt fixed it, so i went a read up on things a bit, i wish i had done that before i broke everything,

my questions, did i possibly damage anything by shorting the resistor? any chance i can solder a new one on there (i have done cb soldering before and have a setup)?
trying to not sink more time and $ into this mistake i made, and if there is a chance that a new resistor and lid switch would fix it id go for it, but i dont even know if the lid switch was even the problem in the first place,
might have to just bite tge bullet and buy another used washer :(

the attached photo is of the same cb i pulled off google, the fried component is R050 near the two caps (location r69)
thanks for the input, i love learning about circuit boards, but always seem to have to learn because of stupid mistakes,
last time was cooking a 10-pin mosfet in my cars ecu after replacing a fuse that kept blowing with a bigger one to be able to get home..

The R050 component is undoubtedly a current sense resistor is a high-current path, as it has traces from it that seem to be kelvin sense wires. Shorting it won't work as the control circuitry will read zero current possibly leading to further damage elsewhere.

I hope you can now appreciate that randomly poking a complex piece of electronics is extremely unlikely to lead to a successful repair. Probability is working against you.

Grab a fist full of large bills and buy a new control board. You have just learned a $500 lesson, a bit less if you are really lucky. Randomly bypassing things is a simple way to do serious damage, and should only be done when the intent is to do serious damage.
Otherwise, examining the circuit to locate that part in question may provide an insight as to which terminals can be jumped to bypass an item.
Random shorting is ONLY for when the intent is to do serious damage.

That is the same board in the modern cheap washer I sold for parts at $40 as the replacement board was more expensive than an used washer. The black square part with a hose connector on top is the water level sensor. The diagnostics is very convoluted in the enclosed manual attached somewhere inside the cabinet, uses its panel row of LEDs at top to tell failures.

The fact that only one part is burned does not mean that others are not damaged. So you might possibly be lucky and possibly no other damage has been done.
The washing machine that I repaired, as a "second opinion" person, after the service guy told the owner the board had to be replaced, about $500 for labor and parts estimate, only needed a few minutes unplugged, and then a reset command entered.
It was very obvious that the repair guy had never read the service sheet instructions. But probably he was really good at replacing parts instead of understanding the problems.

It is fraud, plain and simple, to represent that one knows what they are doing when actually they do not have even a clue. Unfortunately there are way too many folks who are unable to see that a service person is clueless. And way to many "wannabe" people who represent themselves as skilled service people when actually they have no clues at all. Of course, I have made some good repairs and fixes after admitting that I don't know, but then saying that I will give it a try. Had quite a few successes that way.

Mechanics sometimes work the same way.
They keep (somewhat randomly) replacing parts until the problem goes away.
For repair companies, it is often a case of economics, rather than pay highly skilled techs, they get by with those with reasonable skills, but who can still complete the job, albeit wade through a few parts on the way.
