Step by step
-
1 Pull the bottom rack and find the filter
The cylindrical mesh filter sits in the tub floor, usually with a quarter turn arrow marking. Twist counterclockwise and lift out, many have a flat coarse filter beneath that lifts out too.
-
2 Rinse and scrub
Hot water and a toothbrush on the mesh until water runs through freely. The grime you’re removing is what’s been respraying onto your glasses.
-
3 Check the sump while it’s open
Feel the exposed sump area for glass shards, fruit stickers, and pit fragments, remove anything that isn’t machine.
-
4 Pop off the spray arms
The lower arm usually lifts or unscrews. The upper arm unclips from the rack. Poke every jet clear with a toothpick and rinse the arms through.
-
5 Reassemble and run a cleaner cycle
Filter locked back in (it must click, a loose filter lets debris reach the pump), arms clicked on, then run the hottest cycle empty with dishwasher cleaner or citric acid. Repeat monthly, non negotiable in Arizona hard water.
