7.3 Replacement Circuit Board Set-up
Jumpers are provided on the Timing Control and the Temperature/Pressure Display boards to set
the program for each machine model (See Fig.7.2.1, page 61, for board locations).
Jumpers are set at the factory for new machines and should not require adjustment.
Whenever a board is replaced in the field,
the service technician must set the jumpers on the replacement circuit board to
match the dishwasher model being repaired.
7.3.1 Timer Control Board Program Jumper Settings
The Timer Control Board has three program jumper settings.
JB1— Enables the basic cycle time for all models and water level control for UH-200 series.
Marked “FWR: fresh water rinse,” for UH-200B and UH-200 and
“F&D: fill and dump” for UH-100B, UH-100, and UL-100.
JB2— Enables the booster function if the machine is equipped with a built-in booster.
