BoilerFaultCodesYour boiler is simply finishing its cooling down cycle after being used and this is a normal part of its operation.
This is a minor fault. Keep an eye on it and mention it at your next annual boiler service. Reset the boiler and see if it clears.
Technical description: Work Pump overrun 2/2 = 3 minutes according to parameter 2/2
What causes this fault?
This code appears when the boiler pump continues to run for a few minutes after the heating or hot water has been turned off. It is a built-in safety feature designed to circulate water through the unit to dissipate excess heat and protect the internal components. Once the system has cooled down to a safe temperature, the pump will stop and the code will disappear.
DIY fix possible
No action is required as this is a normal status code, not a fault.Wait approximately three minutes for the code to disappear.Ensure your radiator valves are open to allow the heat to dissipate naturally.
