What is true of this model and changes how you fix it

Hardware — Whirlpool product page
Built-in hidden-control-console, fingerprint-resistant stainless, 41 dBA, 3rd rack with silverware tray, Sensor Cycle, Soak & Clean cycle.
Drying — heated dry option
Heat Dry option with an element for better plastic drying; keep plastics off the tub floor. Rinse aid helps.
Wash & racks
Stainless tub, a 3rd rack, and a sensor (Adaptive Wash) cycle that adjusts to soil. A manual filter must be cleaned periodically.
The sensor cycle
The Adaptive Wash sensor tests the water and extends the cycle for soiled loads. Long cycles on the sensor and heavy modes are normal, and heated drying adds time. It is thoroughness, not a stall.
Heat Dry
A Heat Dry option with an element improves plastics. Keep plastics off the tub floor, and keep the rinse-aid tank filled.
Racks and filter
A stainless tub, a third rack and a manual filter that must be cleaned periodically. A clogged filter is the first cause of poor cleaning.
When a cycle is too long
Use a one-hour or express cycle when you do not need the sensor's thoroughness, and check the filter and the incoming water temperature if the cycle seems long on every setting.
The hidden console
With the controls on the top edge of the door, the display is visible only when the door is open. A time display on the floor or a status light shows progress during the cycle.
Finding the model number
The label is on the inside edge of the door; Whirlpool lists the full model as WDTA50SAHZ.
The Soak & Clean cycle
A Soak & Clean cycle soaks heavily soiled dishes before washing. It is long by design, so do not choose it for an ordinary load, and it is a good alternative to pre-rinsing dishes with baked-on food.
A hidden console and its lights
With the controls on the top edge of the door, you see a few status lights on the top edge rather than a display. Learn what the lights mean in the manual so a flashing light is read as a message and not as a fault.

Exact questions

Questions that only have an answer for the Whirlpool WDTA50SAHZ dishwasher

My Whirlpool WDTA50SAHZ cycle takes hours.+

Long cycles are normal on the sensor/Auto and heavy modes — the Adaptive Wash sensor tests the water and extends the cycle for soiled loads, and heated dry adds time. That thoroughness is by design, not a stall. Use a one-hour or express cycle when you do not need the full clean. If it seems stuck at one time for very long, that is usually the sensor holding while it heats water, which a hotter incoming supply shortens.

Why does my Whirlpool WDTA50SAHZ cycle take hours?+

The sensor cycle extends the wash for soil, and heated dry adds time.

Can I shorten it?+

Use a one-hour or express cycle.

Does Heat Dry help plastics?+

Yes.

Where is the model label?+

Inside the door edge.
