Possible Causes

Loose drain hose clamp, Cracked drain fitting, Improper air gap installation, Drain line backpressure

How to Fix / Troubleshooting

Safety: Be cautious of slippery floors. Place the unit in bypass and unplug if working near electrical components.

Steps:

  • Inspect drain connection: Check the hose clamp and barb fitting at the valve head. Tighten or replace as needed.
  • Check air gap: If an air gap is used, ensure it is not clogged or overflowing due to a blocked house drain.
  • Secure hose routing: Make sure the drain hose is properly supported and not pulling on the fitting.

Resolution: Replace damaged drain line fittings or hose. Clear any downstream drain blockages to prevent backpressure.
