  If you find that your Daikin Water Heater is continuously discharging water, there are several possible causes and solutions: * **Cold water inlet pressure:** Check the pressure reducing valve. If the measured pressure is greater than 2.1 bar, replace the pressure reducing valve. * **Temperature and pressure relief valve:** Check and reset the button. * **Expansion relief valve:** Check the pressure relief valve by turning the red knob counter-clockwise. If you don't hear a clacking sound or the water continues to run, contact your local dealer and close both the water inlet and outlet shut-off valves first.
