Potterton Promax 15/2 HE Plus tripping out

[Kewat66]

Hi All,
i have a potterton promax 15/2 HE plus that keeps tripping out. Press the reset and the boiler lasts for about 2 days. I going back to it but because of the design the fault light sequence can only been seen with the cover removed and due to timing of getting back and the client pressing the reset to keep the boiler going it is becoming a bit of a problem. Obviously the light sequence helps point you in the right direction but has anyone got any ideas why this may keep happening?
thanks

Could be absolutely anything! Really need see fault sequence to give some idea where going wrong.
Check gas. Electrodes. Burner. Burner door seal. Condi clear.
