Celebrating/talking about repairing stuff, the right to repair stuff, and the intersection of tech and solarpunk ideals.

What does it mean to use what we have, including technology, to try to build a better, more environmentally just world?

Washing machine PCB has a USART port. Do repairers use that? (lemmy.dbzer0.com)

A washing machine is trapped in a fault state even though all the components function (AFAICT). The controller board has two ports:

ISP (to attach an ISP programmer to flash new software)

USART (4-pin serial port: 0v, TX, RX, 5v)

I’m guessing the ISP port is useless without whatever proprietary software is needed. But what can the USART do for me? Can that be used to obtain the error code and clear it, or reset the board to the factory state? Has anyone done that, without documentation?

You might see if you can find a service manual for the specific make and model, it could be as simple as a hidden breaker switch that flips to factory defaults.

Of course not all makes and models are out there, but a lot are!
