On the display panel - in the box that shows the internal temperature of the boiler it flashes between the temperature and showing SE? What does this mean and what do we need to do?
I am no expert in this but I had it with mine not long ago .It makes you aware a service is due after so many hours of use .If it has been serviced recently you can phone Bosch who will give you a talk through pressing different buttons to clear the message .
I hope this helps .
