Maintenance Keep the dryer clean to prevent decreased performance and to lengthen its life. WARNING The control board and inlet valve are intentionally not grounded and may present a risk of electric shock only during servicing. Service personnel - Do not contact these parts while the dryer is energized. Vent sensor The dryer features a vent sensor that detects and notifies you when it is time to clean the ductwork. The indicator lets you know the status of the duct. Level 0 1 2 Indicator Off On Blinking Status The ductwork is not clogged. • The duct or lint filter is clogged. • The pressure applied to the duct is high because the duct is too long or bent. • The duct or lint filter is severely clogged. • The pressure applied to the duct is very high because the duct is too long or bent. Action • Check the lint filter or duct and clean if necessary. • Check the duct connections and shorten or straighten the duct if necessary. • Check and clean the lint filter or duct and make sure they are not clogged. • Check the duct connections and shorten or straighten the duct work. If the dryer is in the Level 2 state, the indicator blinks for 3 hours after the completion of the current cycle. If you press POWER or open the door, the dryer powers off immediately. NOTE • For duct installation, see "Exhaust ducting guide" on page 28 and "Ducting requirements" on page 14. • The dryer may keep running even if the duct is clogged, but the drying time will be extended. • If the indicator turns on for the first time and is solid (not blinking), check and clean the lint filter and/or duct. • If the indicator turns on again later, it is because the duct is installed or connected with some restrictions (it's too long or has too many bends). This is not a system failure. However, drying time may be extended or the drying performance may be degraded. Maintenance DV7500K-03381C-02_EN.indd 55 English 55 4/7/2016 5:05:55 PM
