ADJUSTING CUSTOMER-
FOCUSED DRYING MODES
NOTE:
If the customer is complaining about the
clothes being damp and the moisture sensor passes
TEST #5, page 7, step 3, the total dry time can be
lengthened by changing from a “1” (standard auto
cycle) to a “2” (15% more drying time) or “3” (20%
more drying time) auto cycle.
1.
Press and hold the Dryness button for
5 seconds. The dryer will beep and display
CF
for one second, then the current drying mode will
be seen on the display. The factory default value
is “1”.
2.
To select a different drying mode, press the
Dryness button again. The dryer display will flash
and show the available settings.
3.
With the display flashing the selected drying
mode, press the Start button to save the drying
mode and exit (the Start button in this mode
does not start a drying cycle). The result will be
stored in EEPROM of the control board, and will
be retained after a power loss.
