What causes the Potterton E130 fault?
This fault occurs when a safety sensor detects that the exhaust gases leaving your boiler have reached a dangerously high temperature. It is usually caused by a build-up of debris or limescale inside the main heat exchanger, which prevents heat from being transferred to your water and instead sends it out through the flue. In some cases, the sensor itself may have failed or there could be a blockage in the chimney preventing the hot air from escaping.
