My Quiet Partner II shows no signs of life. I have checked the power to the unit and have 120VAC all the way to the thermal switch. I removed the thermal switch and ran a continuity test: it is closed. The door switches also test fine: open when they are supposed to be open. Closed when they are supposed to be closed. Still not a peep of life on the front panel. Not one LED is lit. Any suggestions? Thanks.

Movius, You'll need to check for 120 VAC into the control board. *** Be careful, don't shock yourself *** At the control board, with power to the dishwaser supplied,(wether the door switches are activated or not). You should read 120 VAC from CON 1 P4 (white/purple stripe) to CON 2 P6 (black/ white stripe) This will tell you if the thermal fuse has power out to the control board. Here's a quick test, to help determine if you've got a bad control board, Part number: AP4303742
Or controlpanel/keypad assembly Part number: AP3774267
CHECKING KEYPAD OPERATION
A rapidly blinking LED over one of the keys of the keypad (or sometimes a “dead” keypad/console) indicates one or more key switch lines are stuck or shorted on either the control or the keypad. To determine if the control or
keypad is faulty, do the following test:
1. Unplug dishwasher or disconnect power.
2. Open the dishwasher door.
3. Open console and disconnect the keypad ribbon connection from the control (at P1). Make sure all other connections are made.
4. Put console back together. Do not close the dishwasher door.
5. Plug in dishwasher or reconnect power.
6. Wait 5 seconds.
7. Close dishwasher door.
8. Monitor the control’s response:
➔If the control is OK (no longer sees shorts with the keypad unplugged), it will respond by
turning on a Drain Motor for 2 minutes. Check and/or replace the keypad if the control responds OK.
➔If the control is not OK (still sees shorts with the keypad unplugged), then the drain
motor will NOT respond and will remain off. If no response, replace the control.
Good Luck,
:) :) :)
