I'm trying to find out why my dishwasher suddenly stopped working. Based on what I see on the front control panel, the spec sheet said it's either the control board or the control panel (keypad). I followed the fixes below per the tech spec sheet instructions, but still no go. Can someone help? BTW, I have a multi-meter, but I'm still pretty much a newbie when it comes to electronics. All testing was done with the X10 ohms setting.
Control board:
I got a new one and installed it, but now the LED display on the dishwasher does not come on at all. It worked with the old board. I removed the new board and checked resistance on all the resistors. I placed a probe directly on the wires on either end of the resistor itself. I tested every one and got about 0-10ohms on most, but infinity (or very close to) on a few. Does this mean I got a bad board? Since the display didn't work, I couldn't try to run the diagnostics/reset function on the dishwasher so I'm thinking it's a bad board.
Control panel:
The spec sheet had a table where it tells you how to test each switch for the keypad. It says to place the positive lead on a certain pin on the ribbon cable, the negative on a certain pin, then press the corresponding button on the keypad. I had infinity on every one of them. However, just for grins, I tried reversing the probes and got about 10 ohms on every one. I don't know if I'm calling them pins by mistake, but they are the contact points on the side of the ribbon cable connector, numbered from one to 14. The cable was disconnected from the board and power off. Am I doing this right? Why do I only get continuity with the probes reversed? Or am I wrong and they aren't switches at all? I had been told these keypads are button switches where the light above the key lights up when you select it. My dishwasher is a Kitchenaid Superba KUDSO1ILBL6 if that helps.
Thanks!
