ERR9 — Continuous water filling due to valve failure

What does ERR9 mean?

This code, similar to ERR8, indicates too much water in the tank, but the causes are different. It means the liquid valve has burnt, or the triac controlling the filling valve is burnt, preventing the module from stopping water supply.

• Liquid valve has burnt out
• Triac controlling the filling valve was burned
• Control module cannot stop water supply to the tank
