Drain hose drip

Water dripping from drain hose — Blocked or closed outlet

Panasonic · Aquarea Heat Pumps

What does Drain hose drip mean?

Water may drip from the drain hose if its outlet is closed or blocked. The drain hose needs a clear, continuously downward path to ensure proper drainage.

Common Causes

  • The drain hose outlet is physically blocked by debris or an obstruction.
  • The drain hose outlet is inadvertently closed or pinched.
  • The drain hose does not have a continuous downward slope, causing water to accumulate.
