19.5: Diagnostic Test Modes
19.5.1 Power on Reset (POR) Auto Test Mode:
Every “power on reset” (POR) will initiate with an “auto self-test”. The user interface display will
simulate normal operating conditions during the auto self-test.
This auto self-test mode will initiate at the beginning of the initial appliance start-up and after
power is restored after every loss of power that might occur due to customer or supply voltage
reasons. This function could result in a service call, so it’s possible that customer education
could be applied.
During the POR auto self-test mode, the appliance will operate as follows:
The display will show the last machine state.
The interior lights will function normally.
The “Lock” feature will function normally.
The “ON/OFF” key works normally.
o NOTE: if the appliance is turned “Off” during the POR self-test, the appliance will
be disabled immediately.
The “Delay Start” feature works normally.
o NOTE: if “Delay Start” is selected during the POR self-test, the appliance will
enter the selected delay start setting after the completion of the POR self-test.
19.5.2 Manual Auto Test Mode:
The manual auto test mode is activated manually by pressing and holding the “LOCK” key then
pressing the “Delay Start” key (again still while manually pressing and holding the “Lock” key).
The display will flash 5 times to indicate that the manual auto test mode has been enabled.
NOTE: The execution of the auto test sequence is identical in either the POR auto test or
manual test mode.
