  If your DeLonghi Dehumidifier shows error codes like “E2”/”E3” or the “PUMP” symbol, it could indicate several issues: * The tank might be missing, so ensure it is replaced. * The tank could be full, requiring you to empty it. * The tank might be incorrectly positioned, so reposition it correctly. * Low room temperature can cause this issue, so increase the room temperature. * Check that the hose is correctly positioned and disconnect and reconnect the plug.

  If your DeLonghi Dehumidifier doesn't start immediately and you have to wait 3 minutes, it's likely because the safety device has tripped. Simply wait for 3 minutes to pass; this is normal operation.

  If your DeLonghi Dehumidifier is running but the humidity isn't decreasing, here are a few things to check: * The filter might be blocked, so try cleaning it. * The room's temperature or humidity might be too low; in this case, it may be normal for the unit not to dehumidify effectively (consider heating the room). * Ensure the humidity set point isn't too high by decreasing it. * Consider that there might be too many humidity sources in the room, or that the room might be too large for the unit's dehumidifying power.
