Hi Alan thanks for reply the manual does not give resistance for the flame electrode it gives the resistance for the coils on the gas valve & the voltage readings on the flow sensor 5v & 1.5 to 3.5v when you turn on the water tap . The boiler is just under 10 years old & never let me down & it does get used all the time ( me been a cold A ) the heating is on most of the year & the electrodes are like a car spark plug & they must wear out so for £30 you get the 3 electrodes as a kit with gasket so I will compare resistance readings regards Bob
