Direct answer
Modern cycles extend time to compensate for cooler water, soil sensing, energy-saving heat and drying. A sudden increase can also indicate low inlet temperature, excess foam or repeated heating.
What this covers
- Dishwashers · cycle timing
- The exact symptom in the title before component-level repair
- Consumer-accessible controls, connections and maintenance areas
What it does not cover
- ×Smoke, burning odor, swelling, liquid on powered parts or damaged wiring
- ×Opening sealed panels, bypassing interlocks or live-electrical testing
- ×Account ownership, billing or warranty disputes
Observe before changing anything
ReversibleRecord the selected cycle, incoming hot-water temperature and stage where time stops changing.
Isolate the failing boundary
ReversibleRun the kitchen hot tap first, use correct detergent and compare a normal soil load with an empty diagnostic cycle.
Apply the narrow correction
ReversibleCorrect the water temperature or foam source and avoid interrupting sensor pauses.
Verify the result and stop at the boundary
ReversibleService is appropriate when the timer stalls at one stage and water never heats or circulates.
