After checking float pump micro switch we are able to run dishwasher on rinse hold/cycle without any problems and completes it's cycle in the 10 minute time frame of which the manual states but when we try to run a regular wash cycle it continues to run for at least four hours (instead of the 135 minutes listed in the manual) and has an occasional flooding out of the front of dishwasher. Dishwasher does not seem to get hot during the wash cycle. Is the NTC part still the problem?

They are: the control module, the heater and the NTC/limit thermostat. Most common cause of such problem with all Bosch dishwashers for number of years has been a faulty control module . The last 2 numbers in the model number which you posted does not match any available. The closest is 14. That's why I'm not able to verify for you the part number for the control module. Check the model number and repost it. Gene.
