Classic (Formerly Built-In) Error Code H2 LO

Cause:

  • Water valve was energized continuously for 150 seconds
  • 1 gallon of water was dispensed within 15 minutes

Topics:

  • Error code H2 LO, H2 L0, H2LO
  • After dispensing water, unit shows H2LO on display
  • H2 LO displayed on the control panel, and water will not dispense
  • Dispenser locked and will not dispense water

Steps to Verify Issue:

H2 LO on the control panel of a Classic (Formerly Built-In) unit indicates 1 gallon of water dispensed within 15 minutes, or water valve energized 150 seconds.

  • The water dispenser is in lock mode.
  • This is a safety feature designed to prevent a stuck key from flooding the home.
  • The unit will automatically unlock after 45 minutes

To bypass the lock:

External Dispensers (BI-42SD and BI-48SD)

  1. Press and hold the dispenser Light key (above the illuminated key icon) for five seconds.
    • It is possible a small amount of water will dispense after five seconds. This is normal.
  2. The unit will beep two times, and the dispenser unlocks.

Internal Dispensers (BI-36UFDID, BI-42UFDID, BI-42SID, and BI-48SID):

  1. Firmly press the dispenser Water key five times within 20 seconds.
    • It is possible a small amount of water will dispense on the fifth push. This is normal.
  2. The unit will beep two times, and the dispenser unlocks.
