This is my first time with an apartment that has a dishwasher.
Often when I wash a load of dishes, bits of particles get deposited and
dried on the top portion of the dishes, especially stainless steel.
Does anyone know the cause of this?


Yes, it is not working properly. Even the low cost DW do a pretty good job
today. If stuff is getting on the dishes it is probably not filtering
properly and perhaps not draining properly leaving residue behind..

Check to see that the filter (usually on the bottom around the center of the
arm support) is not clogged, be sure the DW drains between cycles.
