I just had a repair technician come and take a lot at my washer — which has started to make some unusual noises. His prognosis: “The good news is that it still works, and using it while it’s making these noises won’t do any harm. The bad news is that I can’t fix it because it needs one key part that isn’t made anymore. The better news is that you wouldn’t want me to fix it anyway … because the cost of repairing it will be more than half the price of a new one.”
You have found the diminishing return point when it finally gives up the ghost.
