My dishwasher has an LED display countdown timer that shows the approximate amount of time remaining on a cycle. The dishwasher stopped working except for the "short cycle". I replaced the control board and front panel. Now the dishwasher works except for one problem. The timer doesn't start counting down immediately. It lights when you select a cycle and when your press start a dash starts to move around the display clockwise. After about 5 minutes the timer starts to work normally showing the time remaining. Your representative suggested that it might be the thermistor causing the problem. I ordered a new thermistor but it didn't fix the problem either. Any suggestions?
