HybridCare™ Dryer with Heat Pump Technology
TESTING
For Service Technician Use Only
TEST #5a: Adjusting Customer-Focused
Dryness Level
NOTE: If the customer complains about the clothes being less
dry or more dry than desired and the moisture sensor passes
TEST #5: Moisture Sensor, step 2, the total dry time can be
lengthened or shortened by changing the Customer-Focused
Dryness Level from “ 1 ” (standard auto cycle) to a “ 2 ” (15%
more drying time), “ 3 ” (30% more drying time), “ 4 ” (15% less
drying time), or “ 5 ” (30% less drying time) auto cycle.
1. In standby mode (dryer plugged in but not powered up),
press and hold the
DRYNESS LEVEL
button for approximately
3 seconds. The dryer will beep and “
CF
” is displayed followed
by the current dryness setting on the 7-segment display. The
factory default value is “
1
”.
2. Pressing the dryness level button cycles the dryness setting
between 1, 2, 3, 4, and 5 in that order, starting at the current
setting. The new setting is displayed in the 7-segment display.
3. With the display showing the desired dryness setting, press
the
START
button to save the drying mode and exit to standby
mode (the START button in this mode does not start a drying
cycle). The result will be stored in EEPROM of the CCU and will
be retained after a power loss.
NOTE: If there is no user activity for 20 seconds, or a button
other than START or DRYNESS LEVEL is pressed, the dryness
setting is reverted back to its previous setting.
4. Press the
POWER
button at any time to cancel changes and
exit from this mode.
