What causes the Ravenheat E06 fault?

This fault occurs when the water inside the boiler is unable to move away from the heat exchanger quickly enough, leading to a rapid rise in temperature. The most common reason is either a failing circulation pump that isn't pushing the water through the system or a faulty temperature sensor that is sending incorrect readings to the boiler's computer.

This issue often comes to light during the first cold spell of autumn, when the pump has been sitting idle all summer and becomes seized upon restart.

Typical repair cost £90-180 (including labour)

DIY fix possible
