@9eurosyltbesucher @SwiftOnSecurity my washing machine has the whole motherboard filled with some kind of resin. No way anyone can fix it.

@dtelder @9eurosyltbesucher @SwiftOnSecurity yeah, these days it's a thin spray, in the past they sometimes used a layer of epoxy.

But it's for moisture (shorts), not preventing repairs

@dtelder Pretty sure it'd be "fix"able. All it does is listen for a few button presses, control a motor, switch a pump on and off, and open and close a pair of solenoid valves. And maybe blink a few lights. Yank the epoxies p on out and replace it with an Arduino and maybe a few SSRs. That's what I plan on doing with mine if I ever need to, it's super solidly build and the spares like the solenoid and the pump are still readily available.

(I've _almost_ done it anyway, to get rid of the stupid tune it plays when it's finished. Though if I cared enough I'd just snip the beeper wires.)

@bigiain @dtelder @SwiftOnSecurity If you want to save a bunch of time, there are generic washing machine control boards available on aliexpress.

@9eurosyltbesucher @bigiain @dtelder @SwiftOnSecurity I need more info on this. Our washing machin keeps flashing some error code. It'll run half the program, get an error. I push the button, it runs for a bit again, rinse and repeat (if you pardon the pun).

Apart from that it seems fine.

@thelovebing @bigiain @dtelder @SwiftOnSecurity this is a version for a frontloader for example youtu.be/x7UJUXwy-MY?si=FB2FCo
They also make one for top loaders.
But you probably should look into the error code and try to fix it as that is probably easier.

My Samsung shows errors in the display. And there is an app to decode them. Original fault is about write memory fail, which cause it to stop. Happens seldom. The error on the picture might be something else. Just an example from my machine...

I think my machine is beyond the replace-by-arduino era. But it is within the modernise-by-arduino range.
My plan is still to hook up the srduino between display and main pcb to sniff status and perhaps start it remotely. But Ihave not yet identified what is sent on the wires.
