Building A Dishwasher From Scratch

Building A Dishwasher From Scratch


[Billy] was no fan of doing the dishes, but also found commercial solutions lacking. The options on the market simply didn’t fit his cookware and flatware. Instead of compromising, he set out to build a dishwasher of his own design. 

The build consists of a whole heap of hardware all lumped in a sizeable plastic tub. A washing machine solenoid lets water into the system, and it’s heated by an element in the base of the tub. It’s then pumped through a garden sprinkler head to give the dishes a good all-over spraying. At the end of a wash cycle, the drain pump then dumps the water to let everything dry off. An ESP8266 and a bank of relays are in place to run the show, with the user selecting wash programs via buttons and a small screen.

It may have taken a couple of years to come together, but [Billy’s] dishwasher seems to get the job done. Files are on Github for those interested, however we’d caution against attempting such a build unless you’re familiar working with plumbing and mains electricity. The other benefit of building your own dishwasher is that you’re less likely to have to patch it against widespread exploits – the security is instead up to you. Video after the break.
