How do you turn on the blue on/off indicator on worcesetr bosch boiler?
My Worcester Bosch Greenstar is working perfectly but following a service the blue/on off indicator is no longer working. I've been told that if I press the spanner button, then the Eco button and the spanner button agani it should come back on. Anyone tried this?
