DIAGNOSTICS & TROUBLESHOOTING

DIAGNOSTICS

1.Turn off the dehumidifier with the power button.

2.Remove the bucket.

3.Unplug the dehumidifier for at least 1 sec- ond.

4.Reconnect power.

5.Within 5 seconds of restoring power, com- plete the following 3-key entry sequence in this order: Desired Humidity, Fan, and Power.

If you press a wrong key during the 3-key sequence, or if more than 5 seconds elap- ses before completing the sequence, you will need to restart the sequence from the beginning.

After pressing the 3 keys in the correct order within 5 seconds, all the LEDs will light at Step 1 (see chart). Use the Desired Humidity key to advance the steps. Using any other key will exit diagnostics.

IMPORTANT: If you do not complete the diagnostics procedure within 15 minutes, the control will exit the diagnostics.
