NTI Matrix Boiler ER4

in Gas Heating
I have a NTI Matrix boiler that shows a ER4 code when the furnace component starts up. There’s no issue when there is a demand for hot water only when the furnace turns on.
I replaced the low pressure switch, manifold limit and stack limit.
Any help will be greatly appreciated. Thanks
