Can you get the relay off of the board without damaging the board and
use some wire to hook up a new relay, remotely? I had to do that with
the run capacitor on my table saw motor because I could not find one
that would fit inside the bump housing on the motor.
Or, call on Jim C for better advice?

I bought this nice LG washer from a guy for $80. It has an
intermittent problem where the drain pump gets stuck on. Turns out it
is a relay on the control board that sticks. This guy has the remedy,
which is basically whacking on the relay to unstick it. I just did
this a second time today, the last time was last winter sometime about
4 months after I got the thing.

So clearly the relay (in the vid the blue one with a sticker on it,
it's about .5"x1.5") is sticking for some reason, it is in a sealed
housing box and soldered to the circuit board. Sourcing a replacement
is probably impossible so I am wondering if I either cut off the top
of the relay plastic box with a dremel wheel to clean it or check it
out, or drill a coupla holes in it and spray in some contact cleaner,
if that might cure it's problem. I'm sure the contacts are just
either oxidized or burned or something and it just needs a good
cleaning. Would this housing hold some kind of oil or something or is
it likely just a protective housing and so opening it would not really
affect its operation? A whole new board is $200some and that would be
stupid to have to buy it for a $1 relay.
Thoughts?
