A hum right where wash should start means the wash pump motor is powered and trying to run — the water just can't get moving, usually from a jammed impeller.
A grinding sound almost always means something hard is caught in the chopper blade or pump area — a bone fragment, glass shard, or fruit pit are common culprits.
If water enters normally but no washing action ever starts, the wash pump or motor isn't engaging — a different fault than a blocked spray arm.
A dispenser door that stays shut is almost always physically obstructed by a dish or the spring/latch mechanism has worn out — both are quick to check and often fix without parts.
A dirty bottom rack with a clean top rack usually points to the lower spray arm or, very commonly, a clogged filter — the bottom rack sits closest to both.
Cloudy white film on glassware is almost always hard-water mineral deposits or etching — two different problems that need two different fixes.
A dishwasher that smells bad even after a full cycle usually has food debris trapped in the filter or drain, or standing water that's gone stagnant.
A small amount of water in the dishwasher's sump is normal, but standing water usually means a clogged filter, drain hose, or air gap.
