No bypass water
Spitting or unusual steaming from
sprayhead or air vent.
1. Bypass valve
2. Recipe settings
1. Lime buildup
2. Temperature probe
3. Control Board
Test the bypass valve. Refer to the
test outputs.
Check to make sure bypass % has
been set for the current recipe.
Inspect the probe and tank assembly
for excessive lime deposits. Delime
as required.
Remove the probe from the grom-
met and submerge in a water bath
of approximately 70°F (21°C).
Connect an ohmmeter to the pins
in the connector. At 60°F (16°C),
the reading should be 15.3k ± 2k
OHMS, at 70°F (21°C) the reading
should be 11.8k ± 2k OHMS, and
at 80°F (27°C) the reading should
be 9.3k ± 2k OHMS. If the probe is
within these parameters, reconnect
to the control board.
Remove power from the brewer.
Connect a voltmeter across the tank
heater. Reapply power to the brewer
and refer to testing outputs. If the
voltage measured when the tank
heater is turned on is very low or
zero, then substitute a control board
know to be good working order.
