What is it? It apparently is obvious when one knows it. The last numbers of the serial number for example. Anyway, it hasn't been changed from the Grant factory set password,,, though it is numbers.
Is this based on familiarity with the boiler. If so I will try it but I will have to press the appropriate button 1234 times to get there.
Thanks tho’
