Starting and Testing Control 

The control at power up will display a “PF” code, that 
shows the control has received power from the 
junction box and is awaiting a command.  The first check 
is to press the START/CANCEL pad, this will clear the 
“PF” code, and the control will be ready for operation. 
The next check for the control with “PF” in the display, is 
to open and close the door.  This opens the door switch,  
the control senses the power loss from the switch, and 
the “PF will clear from the display” and the control will 
be ready for operation.  
If after either of these tests the “PF” still remains in the 
display, the control is not reacting to commands and to 
the presence of power from the door switch.  The 
corrective action is to replace the control.  

If while a cycle is in operation, and a “PF” code appears 
in the display, this is an indication the microprocessor on 
the control has experienced a power loss.  The control 
system needs to be checked for shorts or damage that 
could effect the control.   Replacing the main control is  
the last resort for this condition. 

Water/Service Test

The dishwasher can be tested by use of the water/ser-
vice test.  This test allows the dishwasher to operate all 
the electrical components in a short cycle of 382 
seconds.  This test will not give failures codes or display 
if a component has or will fail, but will in most cases, 
give you time to do electrical checks of the different 
component.  By running this test, all of the components 
are operated in order as they will in a wash cycle so 
operation can be monitored. 
The water/service test is a special function initiated from 
the power failure mode or idle mode.
While in power failure or idle mode - Simultaneously 
press the NO HEAT DRY and START/CANCEL pads for 
1-1/2 seconds.  The dishwasher will then step through 
the test cycle per the chart below.  Pressing the START/
CANCEL pad will advance the dishwasher to the next 
step.   (See Figure 3-9)

Selector Switch 

The display board is used to program the control for 
the desired wash cycle and options.  This display board 
is a circuit board with microswitches for each cycle and 
options.  This board also has indicator lights and two 7 
segment displays to show time remaining and cycle 
status.  The display board has a wire ribbon to connect it 
to the control.  (See Figure 3-10)
To check the selector switch:
With the wire ribbon connected to the control, press a 
cycle pad.  The light for that pad should light after 10 to 
15 seconds.  The light will then go out, proceed to the 
next pad and repeat until all pads have been checked.  
The final check will be to select a cycle and press the 
START/CANCEL pad to make sure the control will accept 
the start command from the display board.  If the unit 
starts or the time starts to count down, the display 
board  has properly programmed the control.
