Question

My Truma water boiler Bs10 will not fire up and there is no sound from the electronic ignition I have power to the switch and to the printed circuit board could you suggest any possible cause,I have taken the cowl cap off Thanks Jack w

Answer

Firstly check that the fuse is intact that is situated on the circuit board. The circuit board will lift out if you remove the triangular top cover and disconnect the wire terminals which are simply pushed on. If the fuse is OK then you may need to replace the circuit board.
