The display shows: • Water supply error.

• This is normal. • This is steam condensation. The dripping waterwill stop after a short time.

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

• Too many or to differenttypes of garments indryer.

• Small loads of 1 to 5 items work best. • Load fewer garments. Load similar-type garments.

• The function of this cycleis to remove wrinklesfrom fabric.

• Use an iron to make creases.

• This is normal. • Depends on individual moisture level in skin.

• Correct drying optionsnot selected.

• Select load weight manually before startingREDUCE STATIC option.

• This is normal. • Depends on the amount or type of garments.

• This is normal. • This is steam condensation on door surface.

9 FLOW SENSOR FUNCTION

How does the Flow sense function display the clogging of duct ?

This FlowSenseTM function detects the clogging or blocking of ducts.“Clogged” duct vents or hoses decrease efficiency in drying cloths. Clogged vents can also cause fire.This function alarms you, when to clean the ducts.When the alarm about Duct clogging is on display of the panel, your duct vents should be cleaned byyourself or serviceman.

The FlowSenseTM display consists of four barsinside a box. The display has only three possibledisplays as only three possible displays as shownhere (Also see the figure shown below):
