Technical description
Water pump overrun – time for heat mode
What causes this fault?
This is a normal operational feature rather than a fault, occurring when the boiler finishes a heating cycle and needs to dissipate residual heat. It happens when the internal pump keeps running for a pre-set period to move hot water away from the heat exchanger, preventing the unit from overheating internally. The status will clear automatically once the internal temperature has dropped to a safe level.
DIY fix possible
No action is required as this is a normal operational status message, not a fault.Wait a few minutes for the status code to change once the cooling cycle finishes.Ensure your radiator valves are open to allow for proper heat dissipation.
