Francisco for Model Number GU2800XTVY0 Hello, I own a Whirlpool Quietpartner V Dishwasher and I'm Getting the sanitize led light blinking at the end of the cycle when I select sani-rinse and heated dry options, the reason I believe is the temperature not reaching the preset value, the dishwasher will not dry the dishes and they do not end up as clean as they used to eventually the dishwasher will end up smelling very badly, the hoses and lines seem to be working just fine, but I've come to notice that the temperature is the main issue. I've tested the Heating element, the High temp limit thermostat, and they seem to be ok, I've also changed the turbidity sensor as my model has a thermistor built-in in this part, however, the problem persists and I do not know how to test the Turbidity sensor itself to see if I got a faulty part, or maybe it could be the mainboard? After I run diagnostics everything seems to be ok, no fault reading on the LEDs. I also changed the mainboard trying to find a solution. thanks.
Answer Francisco, to test the thermistor in the soil sensor, it would be tested from the main control at connection P15 pin 3 to P15 pin 1 and it should read between 48-52 ohms at room temperature. However, beings as the main control and turbidity sensor have been changed out, the issue would more likely be with the heating element W10518394 or a wire. The entire heating circuit can be tested from connection P9 to P3 and it should read between 10-30 ohms. If there is not a resistance reading, then there is a break in the circuit that would need to be traced. If the resistance reads out of the tolerance range, then the heater would be the issue.
