SERVICE WARNING LIGHT (All Models except WB5E)
All models except WB5E have this facility. This light is designed to help you
discover the cause of any malfunction. If the circuit senses a problem, the
service light will flash a number of times and then pause and repeat this
sequence. Count the number of flashes between pauses and refer to the table
on the back cover. Some serious service problems will disable the boiler whist
less serious ones will allow you to continue to operate until a convenient time
arises for the fault to be rectified.
