Apologies in advance for the very, very boring thread topic.
My dishwasher keeps not rinsing properly. Whenever I unload it there are always two or three glasses or cups that have that crusted, crud on the inside. It only happens to stuff on the top shelf and seems to only affect the thing at either end. The stuff in the middle is always clean.
It’s less than three years old and is a good brand - it was quite expensive. I’ve run it on a cleaning cycle with dishwasher cleaner twice, it’s all topped up with rinse aid and salt. I even pulled it out and checked the pipes at the back to make sure there’s nothing wrong there. I rinse off the really mucky things first, too.
Tonight it fucking did it again! Crusty cups and glasses. So annoying. It’s right up there in the top ten of first world problems, I know, but it’s driving me mad. And I’m wasting water washing everything twice. Any tips or anything I haven’t thought of to try?
