Diagnostic Mode 5: Cycle Count at Last Fault (Low Byte).
Diagnostic Mode 6: Cycle Count at Last Fault (High Byte).
The number of Wash Cycles since the last fault is displayed on the Wash Progress LEDs. The low
byte refers to binary* numbers from 1 through to 128. The high byte refers to numbers from 256
though to 32768. Always check both the low and high bytes, and then add the two together to get
the final result.
NB. Even though the last fault gets wiped from diagnostic level 3 after 8 cycles, the cycle number
when the last fault occurs is permanently stored in the memory.
Diagnostic Mode 7: Cycle Position at Last Fault
The Wash Cycle position of the last fault is primarily displayed on the wash progress indicator. In
addition to this, the exact stage of the wash where the fault occurred is displayed via the Wash
Progress LEDs. The 8 Wash Progress LEDs correspond to the 8 stages of a Wash Cycle. Initially,
all 8 Wash Progress LEDs are illuminated and turn off from left to right as each wash stage is
completed.
Diagnostic Mode 8: Water Temperature (Degrees C)
O
The Wash Temperature (of the thermistor in C) is displayed on the Wash Progress LEDs in
binary* form. See Section 5.13 for the binary* conversion chart.
Diagnostic Mode 9: Cycle Count (Low Byte)
Diagnostic Mode 10: Cycle Count (High Byte)
The number of Wash Cycles is displayed on the Wash Progress LEDs in binary* form. The low
byte refers to binary* numbers from 1 through to 128. The high byte refers to numbers from 256
though to 32768. Always check both the low and high bytes, and then add the two together to get
the final result.
Note: The wash cycle count is incremented at the end of the spin cycle.
Diagnostic Mode 11: Motor Speed (RPM)
The motor speed is displayed on the Wash Progress LEDs in binary* form. The current speed
(RPM) can be calculated by totalling the binary* value of the Wash Cycle LEDs and multiplying this
figure by 10.
Diagnostic Mode 12: Water Level
The water level is displayed on the Wash Progress LEDs in binary* form and can be calculated by
totalling the binary* value of the Wash Progress LEDs and multiplying this figure by 2.
Diagnostic Mode 14: Motor Control Software Version
The motor control software version is displayed on the Wash Cycle LEDs in binary* form and can
be calculated by totalling the binary* value of the Wash Cycle LEDs.
Diagnostic mode 15: Display Software Version
The display software version is displayed on the Wash Cycle LEDs in binary* form and can be
calculated by totalling the binary* value of the Wash Cycle LEDs.
* Binary: To calculate a result displayed in binary form, (refer to section5.13)
