Dishwasher hasn't been cleaning very well for a few weeks. Lately we've been getting that horrible white chalky covering on dishes. Yesterday I cleaned the filter, checked the water spouts were clear, topped up salt and rinse aid, switched to liquid cleaner, ran a very hot cycle with white vinegar - basically everything I could think of. Today it's worse than ever.
It's 6.5 years old and, with a family of 5 is on at least once a day. I'm wondering if anyone can think of anything else I can check and, given its age, if people think it's worth the expense of getting someone out to look at it. Not sure how long dishwashers typically last.
