If I were to try this, I would forego hacking the board and instead buy a broken washer, but still good dryer, separately, unless you can find a convincing reason they would need to be one vessel. Then, just fill the washer with a hose and empty with a shop vac, or if you can find a way to open the drain manually. Disconnect the bin from whatever spins it so you could just rotate it manually.

The dryer should then work fine without modification, just change your timing.

As cool as it would be to modify the circuitry of a washer to do the correct cycle, it would be so much work for something that just might function well. I would do the above at least as a test before I moved onto the full monty.

This is an incredible idea though, and I cannot see a reason why it shouldn't be possible, the only stumbling block would be getting control of the thing.

I've been thinking an old washing machine and PLC would work nice for malting.

When malting, do you really soak the grain completely? I always thought you misted them on the floor like when you spout seeds. Once they get to a certain level of germination you dry them to stop the process.

I really have no experience malting so I probably shouldn't have an opinion but that's how I thought it worked.

Subscribed. This is too cool not to watch.

I guess I didn't do full-disclosure, but I'm an engineer for a test and measurement company so it should be pretty easy for me to get some industrial controllers to tinker, so hacking into a motherboard might not be out of the realm of possibility for me. In fact, if I do it the right way I might be able to do a small write-up on it and win brownie points or something.

Before I go ripping things apart though, I will probably contact whatever company who's product it is and see if there's a port I can use for modifying the cycles.

I like the PLC idea, would be more attainable for most people. In particular Arduino might work well as they are affordable, adaptable, and have an extensive code library.

That thing's so old it must have grandmotherboard in it.

not to bring this back from the dead but I've actually built a malt dryer. used a 1979 maytag natural gas dryer. did a few modifications but overall it works really well. im interested in a washer idea...or something im tired of using my bath tub.

What about hacking a steam dryer?

From what I remember from the book The Backyard Homestead, there was a section on home malting grains. I think the grains are submerged and air is pumped through the water. After the acrospires are a certain length the grain is couched by stopping the air flow. I think that the water is changed often to prevent nasties from growing though, hope this helps.
