Could someone tell me what "SE'"flashing on the temperature display means? It's alternating between the temp "62" and "SE". I can't find what it is in the manual?

the SE symbol is pre-programmed into the boiler to flash up after a set number of running hours, it simply means the boiler is due for a service and does not affect the running of the boiler at all. when you have the boiler serviced the service engineer will reset the service interval counter.
the debris seen in the condensate trap is from the heat exchanger and is left over from the casting process, we clean this out when we service the boiler.

Erm how do i reset it? Ive looked in the manuals with no solution. and ive pressed the spanner ( service button ) and 1.A shows. Ive also pressed the reset but still i get the SE flashing.
