7. Slide the CCU towards the back of the
washer to release the tabs from the keyhole
slots in the side panel of the washer and
remove it.
NOTE: Due to continuous improvement
efforts the manufacturer of this washer can
change the software loaded on the CCU
for use on new models. The controls do not
change physical look or dimension, but the
label may or may not indicate the correct
software version on the control. Installing
a control with incompatible software may
cause the washer to not operate at all, to
operate differently, or to develop failure
codes during subsequent operation.
