SHU66C Wash cycles too short

Dishwasher has started showing 55 minute cycle time, instead of expected 90-100 minutes. Only way to get around it is too select Power Scrub Plus. I tried the troubleshootng guide posted by Gene, but this model does not seem to go into test mode with those instructions.:confused:

How it cleans dishes? If it still does it good then there is nothing to worry about.

Here are the break down diagrams and the parts list for the Bosch dishwasher Model SHU66C06 UC/14 (FD 8211-)

If I let it run the 55 minute cycle it doesnโ€™t clean at all.

It also seems to me that whatever component calculates the length of the cleaning cycle is flaky.
