Dishwasher trouble usually comes down to water getting in, water moving around, or water getting out. Most of the time the culprit is a clogged filter, a drain problem at the sink, or a worn pump or inlet valve.
Water hardness plays a part too, and it is worth understanding before you replace parts: scale on the spray arms and heating element makes a healthy machine clean badly.
Symptoms
Check first something you can safely look at yourself · Technician needs tools, parts or testing
Usual causes: Clogged filter, disposal knockout plug, kinked drain hose, drain pump
Clear the filter and check the sink side first. If the pump hums but water stays put, the pump or its impeller is blocked or failed.
Check firstUsual causes: Blocked spray arms, weak circulation pump, low water fill, hard water
Grit on glasses usually means food is recirculating because the filter is full. A white film is scale and detergent residue from hard water.
Check firstUsual causes: Door gasket, tub or sump seal, loose inlet or drain connection, wrong detergent
Regular dish soap in a dishwasher makes suds that push out past the door. Otherwise, the location of the leak points to the seal or fitting.
TechnicianUsual causes: Door latch or switch, control board, child lock, thermal fuse
Check for a control lock first. A latch that does not click firmly will stop every cycle.
Check firstUsual causes: Heating element, rinse aid empty, fan (on some models)
Many modern dishwashers dry by condensation and rely on rinse aid. An empty rinse-aid dispenser is the most common cause.
Check firstUsual causes: Glass or a pit in the pump, failing motor
Stop the cycle and check the sump under the filter for broken glass or fruit pits.

Local
Oak Lawn and most of the surrounding suburbs drink Lake Michigan water treated by Chicago, which the City rates at about 7.6 to 8.8 grains per gallon of hardness (source). That is enough to leave a white film on glasses and scale on the heating element over a few years. Keep the rinse-aid dispenser full, run an empty cycle with a dishwasher cleaner every month or two, and if your dishwasher has a water-hardness setting (many Bosch and Miele models do), set it to match about 8 grains rather than the factory default.

Dishwashers have a shorter working life than most kitchen appliances, and a new standard model is relatively affordable. A pump, control board or tub leak on an older unit is often where replacement makes more sense. Door latches, inlet valves, filters and drain hoses are cheap fixes.
