bottom of the brew basket, 1/3 of the way through the brew
cycle, equals 190 degrees + or - 5 degrees
-Replace spray head
-Use smaller "half batch" brew basket
-Discourage half batch use
-Investigate the need for a smaller brewer
-Move brewer water feed to a non-softened source.
-Call FETCO Service Dept. to discuss.
