Thread: Dishwasher controller

This is not a repair as such but I want to reverse engineer the connections to the controller in my indesit ICD661 dishwasher so that I can run my own wash programs on my own controller controlling the various bits of the dishwasher

Writing your own dishwasher firmware is a little hairy, there is safety to think about with leaving a heater or fill solenoid on. You have to filter and debounce all inputs, and have timeouts if a switch or float gets stuck, pump doesn't work, that kind of thing. But nothing an Arduino couldn't pull off
The controller board looks straightforward, I would see if it's possible to read the dishwasher MCU's firmware and disassemble it.
Just need to post PC board pics and sketch a schematic to assign I/O, the MCU seems to have only 16 pins.

Why you want to update your old dishwasher if you can simply buy a new one with a very good price? I’ve bought my and paid about 600$ and have got a lot of cool functions! You can easily broke it while updating. So my advice is to look around and buy a new one with the options that you want in a new dishwasher!
