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?

If it's an SI or a Junior,yep you are quite right, spanner for 10sec til red, eco once, then spanner once.

Happens sometimes, is accidentally toggled off when the engineer puts it into service mode.
