POSSIBLE CAUSES CORRECTIVE ACTION
Cold water inlet pressure. Check the pressure reducing valve.
Replace the pressure reducing valve
if the measured pressure is >2.1 bar.
Temperature and pressure relief
valve.
Check and reset button.
The expansion relief valve is not
functioning properly.
Check for correct operation of the
pressure relief valve by turning the
red knob on the valve counter
clockwise:
• If you do not hear a clacking
