What a great discussion Julia, I can so relate to everything you've said, called me stupid but I never realized a dishwasher had a filter, I couldn't find it, so when hubby was at work yesterday I looked for the booklet with the operating instructions, read it and showed me where the filter was, at the bottom of the dishwasher, I took it out and gosh it was completely clogged, yet it was working fine, so I cleared it and said absolutely nothing to hubby lol.
If I hadn't found it, then a few months from now if it stopped working I know exactly what hubby would say ''oh gosh Pauline luv you haven't been cleaning filter sweetie'' when it comes to technical stuff hubby thinks I'm clueless, yes he does mow the lawn and fixes everything, but he never touches a vacuum and never does dusting or polishing, he does expect me to do the traditional women's jobs but I suppose he does all the man stuff, as for cars, he'd never never let me near car maintenance in a million years, according to hubby, somethings are best left to a man to work out.
