While this detailed instruction is appreciated, a WARNING would be it is difficult to reassemble some of these parts, particularly rescrewing the reservoir filter and realigning and rescrewing the top covering. Also, this fix does not address the "machine gun" sound our K40 makes.


Worked like a CHARM!!!
