Chris was out of town, but even when he got home, our trouble shooting didn’t get it working.
He figured it was the electronics that were out and ordered a refurbished electrical panel to install.
It took a week to arrive, so yeah, there was dishwashing by hand to do during that time. We used paper plates as much as possible that week.
Chris followed some YouTube videos and easily replaced the electrical panel; the dishwasher has been working quite nicely since then.
Yay for being married to a handy guy (and for you Red Green fans, I find him to be dashingly handsome as well).
