The dishwasher cycle is taking 3 hours to complete - the manual says it should only take 96 minutes. What would make it take so long?
There is a "smartclean" sensor that measures dissolved solids in the water in an attempt to shorten the washing cycle. however if the dishes have much food left on them, then the washer will continue to run untill it gets a "clean" reading, or it reaches the max run time (180 minutes). all energy star dishwasher require the dishes to be throughly rinsed before washing in the machine. trust me, i know how counterproductive this is.

If your dishwasher's cycle times are too long, check these:
Water pre-heating
Cycle not completing
Water pre-heating
Yourdishwasher may pre-heat the water. If so, and if the water entering thedishwasher is cool, the heater may take up to half an hour to heat thewater.
To avoid the wait, increase the incoming watertemperature before turning on the dishwasher. Do that by running thekitchen sink faucet until the water runs hot. Or increase thetemperature of the hot water to the entire house at the hot waterheater.
Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.
Cycle not completing

There are no adjustments for cycle timing. What does affect timing is temperature of the water coming into the DW. The hotter your supply water, the shorter the time to cycle, BUT if your water is too hot, the cycle time may become too short to light the NSF 'Sanitize' indicator. But since the cycle is taking so long, this is an indication that the DW's water heater is not heating the water hot enough to advance the countdown timer in a timely manner. The control logic is waiting for the temp to come up to an appropriate level to ensure adequate washing, rinsing or drying times. Likely your display is showing '1' for a long time as a symptom of this problem, as well.

This link http://www.applianceaid.com/boschDW.html has procedures to run self-tests on various Bosch models. I suspect that you can confirm a 'heater fault' on your unit by running the self-test.

This problem invariably relates to a 'heater fault' which has usually been traced to an open solder joint on the control board located behind the switches/indicator lights on front door. If you have a Torx driver, soldering iron & bit of solder, you can effect a repair yourself in about an hour. Otherwise, a replacement control board is required.

Else, place a service call to the tech of your choice.

Contact Whirlpool service immediately to get a service call scheduled before the warranty expires.
Most dishwashers that begin taking longer to complete the cycle have a failed heating element but that also normally means that the dishes do not get fully clean and the glassware has a film on it after the cycle ends.
Good Luck!

You may be running the sani-wash or heated drying. The heat element in these things takes a long time.
Check these and turn them off - then try another wash cycle and time it to see - should be one hour or less

HI, this is a control fault. the logic chips are malfunctioning. these chips are responsible for initiating the proper washing cycle sequences. you will need to replace this damaged control board asap.
