My 1-year-old Bosch bottom of the line DW has an easily reached filter, but I've yet to find anything in it beyond a bit of what looked like paper toweling. The directions say to merely scrape dishes, but because we only run it alternate evenings, I rinse anything that would start to stink (fish, milk).
Growing up without a father in the house, my DM and I did many chores to save money. DH grew up with 'help'. I'm the 'Handy Annie' in our marriage. (Getting Raggedy, too.) Always interesting to see the light dawn when a plumber, HVAC tech, etc. realizes he's explaining something to the wrong gender.
