BoilerFaultCodesWhat the manual says
Manufacturer manualParameter error on printed circuit board (PCB). Temporary error, will self reset
What causes this fault?
This fault occurs when the boiler's internal computer experiences a brief communication error or a temporary glitch in its stored settings. It is often caused by a minor power fluctuation or a digital 'hiccup' where the board fails to read its own configuration data for a split second. The boiler usually detects this inconsistency and performs an automatic reboot to clear the error.
DIY fix possible
Wait for the boiler to complete its automatic self-reset processMonitor the display to see if the flashing stops naturallyIf the flashing continues for more than 10 minutes, try turning the boiler off and back on at the fused spur switch
