I'm having issues with my Fridgidaire dishwasher Model FDBB2040FS3. At first the unit would stop running after 10 minutes and the Hi-temp and Air Dry buttons would flashing at the same time. It was fairly consistant at stopping after 10 minutes each time. After researching this issue I replaced the control board. After replacing the board, the unit ran for 20 minutes but stopped and the Hi-temp and Air Dry buttons flashed like they had previously. After running the unit several times, it was consistently stopping around the 6 minute mark each time and the Hi-temp and Air Dry buttons would then flash again. I need some additional help troubleshooting the potential problem. One question, should the heating element be hot at any time during the first part of the washing cycle? I always run the hot water prior to the wash cycle to make sure the water temp is high enough. Any help would be appreciated. Please feel free to ask any other questions. Thanks.
