Hi,
Have an Ariston microgenus 23 MFFi with faulty flame rectification and would like to ask if these have a history of faulty pcb's. The boiler lights and continues to spark before going to lockout condition. The sensing probe seems to be clean and sitting in flame ok.
Thanks

Thanks for the advice, appreciated

when replacing the pcb due to flame rectification problems please consult ariston technical services prior to installation.
the pcb's supplied are a universal board to fit a range of models and need to be set up for your specific appliance.
if the board is not set up correctly for your appliance the new board will be burnt out instantly due to the electrical switching arching.
