Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.
This is a water pressure too low error. You need to bump the system pressure up to more than 12 psi
There should be a feed valve on the cold water line feeding the system (see attached pic for typical). It should automatically keep water pressure above 12 psi. Seems it's not working. I need to know which brand & model you have. If it's not the same one in the pic then I need the brand and model of the one you have. They are all similar shape but a different color. If you can't give me the model then I need a pic. You can post one here by clicking on ADD FILES next to the SEND button.
Give me a pic of the piping around the boiler. I have heard of cases where they haven't been installed but it's a rarity here in the States while it's common in the UK
You need to post it here. I can't get email and if you emailed it to customer service I won't see it until tomorrow. Click on ADD FILES next to the SEND button to post a pic here.
I don't see it. Where is the expansion tank?
Piping diagram shows it piped into the expansion tank connection
That's the well tank not the expansion tank for the heating system
It's probably piped into one of the orange PEX lines I can see in your first pic
There is no dial near the expansion tank but the feeder may be nearby. There's only so much I can do from here. All I can do is identify the problem and tell you what you need to do to correct it which I've done. The rest is up to you. I'd appreciate a favorable rating. BTW pic of the most common brand of expansion tank attached
I stayed with you well past my usual log off time of 7 pm Eastern. I thought you had given up we can continue if you like.
