Long cycles on the GE Profile PDT785 are a sum of documented add-ons. GE's manual says actual cycle times vary with soil level, water temperature and options, and that the Normal cycle, which was used to rate the dishwasher's energy efficiency, tops out at 1 hour 50 minutes of washing time. On top of that, Auto Hot Start can add up to 25 minutes if incoming water is too cold, Temp Boost adds 20 to 50 minutes, Steam-Sani or Sanitize may add 60 minutes, Dry Boost may add up to 64 minutes and Bottle Jets up to 23 minutes. Deselect what you do not need, and warm the water first.
Differential
Likely causes of “GE dishwasher cycle takes too long”, and how to tell them apart
- 1
Cold entering water triggers Auto Hot Start
What separates it A cycle 25 minutes longer than expected in cold weather
How to confirm Run the hot tap nearest the dishwasher until hot, then start
- 2
Options are adding time
What separates it Temp Boost, Steam-Sani, Dry Boost and Bottle Jets each lengthen the cycle
How to confirm Deselect the options you do not need, and start the cycle again
- 3
AutoSense senses heavy soil
What separates it The cycle extends after sensing the soil level because AutoSense senses heavy soil
How to confirm Let it finish, or use Normal or 1-Hour Wash for lighter loads
- 4
UltraFresh is running between cycles
What separates it Water is added and drained and the fan runs when no cycle is on
How to confirm This is normal while UltraFresh is on; press UltraFresh again to turn it off
Before you touch a setting
Record this first — changing settings destroys the evidence
- The cycle and the options that were selected
- The time at which the dishwasher started and finished
- Whether the hot water was hot before starting

0 of 5 completedKnow the base times
ReversibleNormal is the rated cycle, with a washing time that tops out at 1 hour 50 minutes, Light/China and Rinse are shorter, and 1-Hour Wash is designed to quickly wash lightly soiled dishes.
Warm the water
ReversibleTurn on the hot water faucet nearest the dishwasher and let it run until the water is hot. Cold water can trigger Auto Hot Start, which may add up to 25 minutes.
Count the options
ReversibleTemp Boost adds 20 to 50 minutes; Steam-Sani, Presoak-Sani or Sanitize may add 60 minutes; Dry Boost may add up to 64 minutes; Bottle Jets add up to 23 minutes; 1-Hour Wash with Dry Boost adds 49 to 90 minutes.
Use Wash Zones for small loads
ReversibleSelecting the Upper or Lower Wash Zone targets one rack, which shortens the cycle and conserves energy when dishes are in only one rack.
Check UltraFresh
ReversibleWith UltraFresh on the fan may run and water may be added and drained outside a cycle; that is normal, and pressing the pad again turns it off.
Model-specific
What is true of this model and not of its siblings
