Question about Frigidaire Dishwashers
Rinse only cycle works. Heavy and Normal cycles will not count down and continue to run for hours. China cycle count down to 47 minutes and then continue to run. Changed control board and user interface. Still same. Checked heating element for continuity. It is good.

If your heat cycle is not coming on, which it sounds like it is not, then you may have a problem with the heating system. There is a well known issue with many of the Bosch dishwashers that use the (266746) control module. Basically, there is a relay (which is a kind of electro-mechanical switch) that is used to turn on the built-in heater. There is a solder joint on the main Printer Circuit Board (PCB) that allow electricity to flow to the heater, that joint often will melt away and burn the surrounding area of the PCB. This is most likely a design flaw and appears to occur at about the 4-5 year mark. One way you can test for this is to run the onboard diagnostics routine that is programmed into the firmware of the micro-controller (brain) of the dishwasher. The way to do so it to press and hold the (Scrub Wash & Delicate/Econo) buttons at he same time and then press the on/off power switch to the on position. The LED lights above both those buttons should begin to flash, when they do, press them both again and the diagnostics program will start. It is a multi-phase program that will run for quite a while. Once it finishes, if it is a heating problem, it will end with a number 2 code in the display. If this is so, then it very well maybe the solder-joint issue on the control module and it will need to be replaced. It runs $128.10 US directly from www.bosch-appliances.com. Good luck.
