Question

Truma ultra heat fire, works fine but the piezo ignition is constantly clicking once it has warmed up. The fire is used a lot. What do I need? Many thanks Kevin ex mechanic

Answer

I assume that you have the automatic igniter box fitted to your fire which can be the problem if the ignition is constantly clicking. Alternatively the ignition electrode could be at fault. Easiest to change the igniter box first as the fire has to be removed to change the electrode.
