So how often do you inspect all your appliances? Is there any routine maintenance you do on the machines?
Usually once a month I check the sumps/screens/filters on the DWs for snots and gunk. I also give the spray arms a once over to see if any snots got caught in the holes.
I send the washers through empty with hot water and some bleach every 6 months of so.
I usually inspect the Maytag once every 3-4 months, by taking the front off. The portable KM I usually inspect around the same time frame too.
As for polishing, thats every week!
