This hub is open, but it stays out of search results until it carries verified content, because an empty page helps nobody. In the meantime, the cross-brand symptom guides cover behaviour that applies to most boilers and hydronics, and the error-code index may already document a code that matches yours.

Before you use a code table
  • Record the full indoor and outdoor model numbers from the data plate, not just the brand name.
  • Photograph the display while the code is showing. Some systems clear the code on power interruption and it can be difficult to reproduce.
  • Note what the system was doing when the code appeared: starting, running, defrosting, or idle. That context narrows the cause faster than the code alone.
