BoilerFaultCodesTechnical description
Solar pump jammed or air in system / Air in solar thermal system.
What causes this fault?
This fault occurs when the solar thermal system is unable to circulate its heating fluid effectively. The most common reasons are a buildup of air pockets within the pipework that block flow, or the pump itself becoming physically jammed after periods of inactivity. This prevents the heat collected from your solar panels from reaching your hot water cylinder.
This fault is frequently encountered during the first sunny days of spring or summer when the solar system is called upon to work at full capacity after being less active during the winter.
