TROUBLESHOOTING
Brew Gauge
Brew Pressure gauge needle value changes often:
o
This is normal. The lowest number (usually 3-5 bar) reflects the incoming line pressure. When
brewing the needle reflects brew pressure (8.5-9 bar). When the brew tanks heat, the water
expands and the expansion valve relieves the pressure at 11 or 12 Bar.
Brew Pressure is Low:
o
Check pump to make sure pressure is properly set
o
Water supply hose to the pump is kinked
o
Water filter is plugged. Check and replace if necessary
Pump Motor Runs; No Brew Pressure:
o
Failed pump, needs to be replaced
o
Brew Solenoid is stuck (can be caused by soap residue not fully flushed after cleaning).
o
Brew Solenoid has failed
o
The line between the pump and the water supply has collapsed or is kinked
o
Hose to the pump is kinked
o
Water filter is plugged. Check and replace if necessary
o
Water supply is inadequate
Readout for Brew Water Temperature Varies by a Few Degrees:
o
The control must “see” the increment just above the set point before it sends a signal to turn off
the heating element. This will allow the electronics to show a reading just above the set point. The
energy from the heating element and the tube for the preheated incoming water are within 1” or
25mm from the location of the temperature sensing probe in the coffee tank. The water pick up
tube for brew water is at the top of the brew group and is in the most temperature stable water in
the tank. Meaning, the readout can show a temperature of a few degrees above your set point,
and may fluctuate due to the heat from the element or heat exchanger, but your brew water is
actually at the set point.
Electronics
All zones read LOW:
o
Check to make sure the element breaker is ON (element switch is to the left). Zones will read low
until the temperature in that zone reaches 175° F. Please allow 20-30 minutes to heat up initially.
