up” the display.
3. Turn the knob to select the desired cycle.

Display and Status Indicators
The display shows the approximate time remaining until the end of the cycle and the washer
cycle status (Fill, Wash, Rinse and Spin).
NOTE: The cycle time is a󰀨ected by how long it takes the washer to ll. This depends on the water
pressure in the home. The “smart” timer “learns” the amount of time it takes to ll the washer and
adjusts the total time accordingly.
If an out-of-balance condition is detected by the washer, an Out-of-Balance indicator will appear
and blink during the remaining portion of the cycle. It will stay illuminated for a short time after cycle
completion. When this occurs, the washer is taking actions to correct the out-of-balance condition and
complete the cycle normally. In some cases, the washer may not be able to balance the load and spin
up to full speed. If the load is more wet than usual at the end of the cycle, redistribute the load evenly
in the wash tub and run a Drain+Spin cycle.
In addition, the display will show:
(Features and appearances will vary)
Wi-Fi Will allow the appliance to communicate with a smartphone for
remote appliance monitoring, control and notications. It stays lit
whenever the washer is on and is connected. It will blink during the
commissioning process or if it loses connection to the network.
Venting
Venting will blink to indicate to select the ULTRAFRESH VENT
feature at the end of the cycle. It then stays illuminated once
selected until venting is complete.
Control The controls on the washer are locked when this icon is illuminated.
The user must press and hold the Control Lock pad to unlock the
controls.
Door This icon will illuminate while the door is locked and will blink while
the washer is in the process of pausing and then unlocking.
Auto, More, Less
(on some models)
The SmartDispense will automatically dose detergent according to
the weight and soil level of the clothes. The user can adjust this
feature to dose 40% MORE or 40% LESS detergent or turn it OFF to
manually dose detergent.
Tank Low
(on some models)
Will display when the SmartDispense tank needs to be relled.
Typically, this rst lights up when there are approximately 8 to 10
loads of detergent remaining.
Loads Left
(on some models)
Displays the estimated number of wash loads left for the amount of
detergent in the SmartDispense tank.
