Brew volume too
large or too small.
Timer out of ad-
justment.

Problem Possible Cause Service Check Remedy
Brew volume erratic.
(there is always some
small variation from
batch to batch)
Timer faulty.
Pressure fluctuations
at brewer.
Measure brew time for
inconsistencies.
Check pressure at
brewer inlet.
If time is different from batch to
batch, replace timer.
Plumb water line so its pressure is
not influenced by other appliances.
Brew will not

breaker.
Brew valve faulty.
Stop switch faulty.
Start switch faulty.

brew valve.
Check for continuity
across stop switch
when not pressed.
Check 120V between
S.S. and N on timer
when start is pressed.
Check 120V between H
and N on timer. If OK,
check for 120V between
BREW and N on timer
after pressing start.
Reset or replace breaker.
If 120V is across brew valve, but brew
valve doesn't open, replace coil or valve.
If no continuity, replace switch.
If start switch does not provide 120V
start signal, replace switch.
If no 120V BREW output from timer,
replace timer.
Spray head will not
stop dripping water.
(spray heads normally
drip slightly after
brew)
Boiling tank.
