IBC IFIRE-B Red LED - 10 Flashes — Water Pressure Fault

Red LED - 10 Flashes

Needs attentionIBC IFIRE-B condensing boilers (manual 241941 Rev. 13)

Water Pressure Fault. Check system piping for leaks. Check water pressure switch (if equipped) and connections. Check wiring on PIM at J1, pins 6 and 7 for loose or missing jumper. The table classifies it as fault (PIM LED).

Applies to

This low-water or pressure protection code is displayed by the IFIRE control on IFIRE-B models (300B–1000B), as documented in IFIRE / IFIRE-B Installation & Operating Manual, doc 241941 Rev. 13 (241941 Rev. 13). Codes can differ between controller generations, so always check the manual that matches your unit.

Controller: IFIRE control. Source manual: 241941 Rev. 13.

Why a code is not a diagnosis

A water-pressure or low-water code can mean a genuine leak or empty system, a failed expansion tank, a faulty fill valve, or a sensor problem. The appliance does not distinguish these.

Safe things to observe

  • Read the pressure gauge and compare it with the normal cold-system pressure your installer set.
  • Look for drips or wet spots near the appliance, pipes and the relief-valve discharge.

Do not

  • Do not keep re-pressurizing a system that keeps losing water.
  • Do not cap a relief-valve discharge pipe.

How professional service helps

  1. A technician finds and repairs the leak, checks the expansion tank and fill assembly, and verifies the sensor circuit.
