Technical description: Pump fault detected by diagnostic feature.
What causes this fault?
This fault occurs when the pump responsible for moving hot water from the boiler to your radiators or hot water tank has stopped spinning or is struggling to maintain the correct speed. The most common reason is that the pump has seized due to a build-up of debris in the system or the electrical components within the motor have reached the end of their lifespan.
This fault is frequently seen at the start of autumn when systems are turned on for the first time after summer, as the pump internal parts can seize if they remain stationary for several months.
