Harry for Model Number GU1500XTLB1 I have a whirlpool GU1500XTLB1 dishwasher. When you press "normal" the two dashes come on the display, but do not move. After a short time the display shuts off. The door switches are both good. I have checked control buttons as described using the diode setting and they all test ok. But in normal operation when you press the buttons not all the lights come on. Do I have a bad control circuit board or push button unit?
Answer Hello Harry. If you have two dashes in the display, you will need to replace the door switches WP8269209 on the unit. If the switches are good, then the latch may not be working properly and you will need to adjust the latch. If the switches and the latch are working properly, you will need to replace the control board WP8564543 in the unit. Hope this helps. Read More...
