Short answer:
Most modern dishwashers run 1.5 to 4 hours, depending on the cycle and soil level.
Why Dishwasher Cycles Are So Long
Newer models use less water and energy, so they clean more slowly but efficiently.
Typical Cycle Lengths
- Quick wash: 30–60 minutes
- Normal cycle: 2–3 hours
- Heavy cycle: 3–4 hours
Is a Long Cycle a Problem?
No. Longer cycles usually mean better cleaning and drying, not a malfunction.
When to Worry
- Cycle runs longer than 5 hours
- Dishwasher never finishes
- Error codes appear
