7.3.1 Timer Control Board Program Jumper Settings (Cont.)
WARNING:
When working on the dishwasher, disconnect the electrical service and place a red tag
at the disconnect switch to indicate work is being done on that circuit.
To set the jumpers JB1, JB2, and JB3:
Check and set the jumpers before you install a replacement board.
1. Turn power off at the dishwasher and the main power disconnect switch.
2. Open the front door.
3. Remove screws located in each corner of the hood.
4. Pull the slide-out control cabinet out fully.
5. Fold back the protective mylar drip shield.
6. Compare the jumper settings on the dishwasher
circuit board with the settings shown in Fig.7.3.1, page 54.
7. Using fingers or needle nose pliers, set the jumper as required.
• The jumper encloses both pins when the switch is closed.
• The jumper encloses one pin when the switch is open.
This method prevents losing the jumper.
8. Replace the drip shield, and close the slide-out control cabinet fully to position the door
safety switch located in the left hand corner of the control cabinet.
9. Close the dishwasher door, turn power on and check the dishwasher for proper operation.
