Navien - CH-240 Low pressure on heating side

Member Posts: 1
Navien CH-240 used as water heater and floor heating. No issues for a year, for no apparent reason the unit showed error code E002 and a pressure reading of 7.x. Manual reads to turn off the system and turn unit back on. This did not fix the problem. Local technician connected a line from the heating water side to the domestic water inlet, this increased the tank pressure to allow the unit to work.
6 weeks later, the same event happened. I applied the same corrective action to allow the system to work.
Why is the system not maintaining tank pressure?
