Anyone ever seen an error code 55 on Noritz Combi boiler?

Yes, that means the inlet pressure to the boiler "auto-feed" is low. Two scenarios, either you have a closed valve on the inlet to the boiler auto feed OR maybe you have a pressure reducing valve on the auto feed inlet. Also, maybe it's possible the auto-feed valve has failed. Also possible that you have a leak in your hydronic heating circuit so its never getting up to full pressure.0
