Tim I think my original directions on descaling left the tubes in the clear water for flushing out the citric acid. this works fine for the steam boiler but takes many trials to flush the brew boiler. When flushing the brew boiler it goes a lot faster to remove the tubes from the reservoir. drain the brew boiler almost dry then replace the tubes to allow fresh water to enter the brew boiler. It is still about a 4 hour process.
