It came with the house, and was pretty old back then. We never used it all that much over the years. But recently it has been used more, and I guess the old girl couldn't cope. | + | {{ :repairs:dishwasher:door-open.jpg?direct&300|}}Two weeks before the [[https://openrepair.org/international-repair-day/ | International Repair Day 2021]], our 26 year old dishwasher from 1995 packed it in.
