Hi,
my boiler had the fault code "flashing" L-F,
the problem was a blocked drain below the second "s" trap.
i have cleaned and checked everything,
water flows from the sump through the 2 "s"traps ,
and the boiler appears to be working fine,
no fault codes,
however, the secondary "s" trap is not filling and emptying water as it should.
i have checked and there is no water is present in the sump to drain.
obviously something is not quite right....
but what?
any advice/suggestions as to what to check?
thanks
