What causes the Potterton 130 fault?
This fault occurs when the boiler's internal components reach a temperature that is dangerously high, triggering a safety shutdown to prevent damage. The most common reason is a buildup of limescale or debris inside the heat exchanger, which restricts water flow and prevents heat from being transferred away from the burner effectively.
This fault often becomes apparent during the first cold snap of winter when the boiler is suddenly required to run at a higher output for longer periods.
