huge amount of water dripping due to:
• high water temperature set point
• high water network pressure
• expansion vessel missing
• drainage hole obstructed
• drainage pipe broken
• Check the valve tuning, the water
network pressure
• Check the water discharge
• Verify water leakage
• If necessary install an expansion
vessel
• Clean the valve hole
• Replace the discharge pipe
