8-2. Troubleshooting for Steam Dryer

PROBLEM

The display shows: • Water supply error.

Water drips from
nozzle when Steam
Cycle starts.

Steam doesn’t
generate but no error
code is shown.

Garments still
wrinkled after
STEAM FRESH™.

POSSIBLE CAUSES

• This is normal. • This is steam condensation. The dripping water

• Water level error. • Unplug dryer and call for service.

• Too many or to different
types of garments in
dryer.

SOLUTIONS

• Check steam feeder drawer:
(1) Make sure steam feeder is filled with water to

MAX line.

(2) Make sure steam feeder is seated properly

and drawer is fully cloased.

(3) Turn the dryer off then restart the steam cycle.
