What to do if the water pressure relief valve opens on my Daikin EWYQ007ACV3P?

If the water pressure relief valve on your Daikin Air Conditioner is opening, it could be due to a broken expansion vessel or the water volume in the installation being too high. Replace the expansion vessel or reduce the water volume to be under the maximum allowed value.
