TROUBLESHOOTING TIPS
Before calling for service, please review the chart below.
AUTO DEFROST
DISPLAYS REPEATEDLY
Turn off unit and unplug 4-6 hours.
Plug unit back in. Run in normal mode (no Turbo fan, not on Continuous operation) and set humidity level to no
more than 5% lower humidity than what the display reads for the room humidity.
Allow time for the unit to run until it successfully reaches initial humidity setting.
Lower humidity another 5% and repeat until desired humidity is reached. (Average setting should be 45-50%.)
Be sure unit humidity is not set too low, unit is not sitting on too cold of a floor and unit is not being used in too
cold of a room. (Room should be 41º F or above.)
Be sure there is sufficient air circulation between the unit and the floor.
Issue Possible Solutions
DEHUMIDIFIER P2 OR
‘BUCKET FULL’ DISPLAYS
Verify rubber drain plug is not removed from back of unit if using bucket to collect water.
Check float switch (inch length silver tab in top of unit behind bucket) to ensure it is not cracked, bent, broken,
dirty, or obstructed. If bent, re-adjust by re-bending back in place. The switch is located on the left side behind
the bucket when you are facing the unit.
Check that unit is level and the filter, vents and bucket are thoroughly clean.
Ensure float is snapped into place inside the bucket and that foam piece is inserted in float. See page 3, Fig. 2.
Unplug unit for at least 5 minutes. Plug back in unit. Remove and return bucket securely, then turn on unit.
DEHUMIDIFIER NOT
DRAWING WATER
Be sure unit is not too large or too small for the area of the room.
When first installed, run unit on Continuous Mode for 24 hours.
Allow enough time for unit to remove moisture.
Set humidity low enough to ensure moisture removal. Setting the unit below 45% is not recommended.
Setting may be the same as actual humidity in room, thus no moisture to remove.
Be sure all doors, windows and other openings are securely closed.
Be sure unit is level and that there is sufficient air circulation around the unit, as well as between unit and floor.
Make sure unit is level and that there are no curtains, blinds, or furniture blocking the unit.
Check that room temperature is 41º F or above.
If unit is near a heat source, such as a clothes dryer, etc., relocate unit.
DEHUMIDIFIER
CONSTANTLY CYCLES
ON/OFF
Be sure unit is not too large or too small for the area of the room.
Using unit in much less than its stated coverage will likely cause it to go on and off more frequently. Using too
small of a unit will cause it to run constantly.
If the humidity setting and actual humidity in room are cycling right around the same, the unit would go off and
on accordingly.
The fan will run for a few minutes after the compressor shuts off. If you have turned the Continuous mode on,
the fan and compresser will not turn off; they will run continuously in this mode.
Check that unit is level and the filter, vents and bucket are thoroughly clean and nothing is obstructing them.
Be sure all doors, windows and other openings are securely closed.
Ensure there is sufficient air circulation around the unit, as well as between unit and floor.
Unplug unit for at least 5 minutes. Plug back in unit, remove and return bucket to dehumidifier and turn on.
This is normal. The dehumidifier has an auto defrost feature. See page 5 for more information. FROST APPEARS ON THE COILS
These are error and protection codes. See page 5 of this manual for more information.
