Last week our dishwasher’s display froze. Instead of showing “2h” or “15” (minutes), it stuck showing a zero then something that looked like a backwards 6. The next time I power cycled it, the display stopped working entirely. The unit still seemed to wash dishes, though. I’d performed repairs once before, when the door latch broke. I had ordered the replacement part from some guy on eBay and done the replacement myself.
