Chart For the Water Service Test
Relay/ Triac and Sensor Test
This test allows the servicer to troubleshoot the
dishwasher by energizing the different devices of the
dishwasher independently from one another. The
best way to understand the value of this test for field
service technicians is the example of testing the
heater for operation. Enter the test followed by
pressing pad number 10 on the keypad (see table)
this will apply power to the heater. The heater will be
powered until the same pad is pressed a second
time.
To access this test the unit must be placed in PF
condition. While in PF press and hold Pad # 1 and
Pad # 7 at which time an “rt” will appear in the
display. You can now follow the chart below as to
how to select the component to operate. While in this
test if you wish to test more then one component you
must always repress the previously selected pad to
leave one component before moving on two the next.
When the tests are completed you must again Press
Pad # 1 and the Pad # 7 this will return you to PF
mode.
This test can only be entered from a PF (Power
Failure) condition. This can be accomplished in two
ways. First is to have the power removed from the
dishwasher then turned back on this will show a PF
in the display and the test can be entered.
The second method to enter this test is to program
the control into a Water/Test, at the completion of
this test then open the door the control goes into a
PF condition now program the Relay/Triac test. By
going through the water test you do not have to
disconnect power to the unit and the test can be
entered rather quickly.
