A Whirlpool WFC8090 that takes a very long time is behaving more normally than it seems, because this is a 2.8 cubic foot all-in-one: it washes and dries in the same drum, and the drying half is a ventless, condensing system. A condensing dryer removes moisture by cooling the air and collecting the water instead of blowing hot air outside, so it is slower and gentler than a standalone vented dryer.
The checks in more detail
A wash-and-dry cycle that runs for several hours is common, and the time on the display is an estimate the machine revises as it senses how wet the clothes are. The next question is what is adding avoidable time. Load size comes first. Drying needs room for clothes to tumble through warm air, and a full wash load is often too much for the drying phase; the manual gives a smaller maximum for wash-and-dry than for wash only, so split a large load or choose a wash cycle and dry in a second step.
Detergent comes second. The Load & Go Plus dispenser doses automatically, and too high a concentration setting produces suds, which show as a Sud or Sd message, extra rinses and a long pause while the machine clears the foam. Use only high-efficiency detergent and check the dose setting. Then maintenance. A blocked lint filter or a coated condenser path slows the drying phase and lengthens every cycle, because the machine keeps running until sensors report the clothes are dry or a time limit is reached.
Clean the lint filter after each drying cycle and the condenser path on the schedule in the manual. Check the drain filter and hose for a slow drain, and a cold water supply on warm settings. If a normal-sized load still takes much longer than it used to, or the drum is still wet when the cycle ends, record the cycle, the load size and any F code and contact Whirlpool.

Record this first — changing settings destroys the evidence
- The cycle chosen and the load size
- How long each phase seems to take
- Whether a Sud or Sd message appeared
- When the lint filter and condenser path were last cleaned

Model-specific
What is true of this model and not of its siblings
- What condensing means
- Moist air is cooled so water collects and drains away instead of venting outside. That makes the combo installable without ductwork, and slower at drying.
- Capacity difference
- The drum washes more than it can dry well, so the drying capacity is lower than the wash capacity in the manual.
- Sensors and time
- The washer senses moisture and revises the time. A damp, bulky load pushes the estimate up, and the cycle may end by time limit.
- The lint path
- A ventless combo has a lint filter and a condenser that need regular cleaning. Lint on the condenser cuts the cooling and lengthens every dry.
- Suds and pauses
- Too much detergent shows as Sud or Sd, extra rinses and pauses; the dose setting on the Load & Go Plus dispenser is the first thing to check.
- Whirlpool help

Exact questions
Common questions
Is a long cycle a fault?+
Often not; a ventless combo dries slowly.
Why are clothes damp at the end?+
The load was too large or the filter and condenser need cleaning.
Does more detergent help?+
No; it creates suds that lengthen the cycle.
Can I dry a full wash load?+
Usually not in one pass.
Can I run wash only?+
Yes, and dry later if that suits.
Does the app show progress?+
Yes, but the estimate is revised as it dries.
