 Diuser screen/screw, or jet is clogged

 Soap residue not fully ushed aer cleaning has glued the valve closed (tap the valve body gently).

 Brew solenoid has been sealed shut by dried soap or has failed.

Brew Gauge

Brew Pressure gauge needle value changes oen:

 This is normal. The lowest number (usually 3-5 bar) reects the incoming line pressure. When brewing

the needle reects brew pressure (8.5-9 bar). When the brew tanks heat, the water expands and the ex-

pansion valve relieves the pressure at 11 or 12 Bar.

Brew Pressure is Low:

 Check pump to make sure pressure is properly set

 Water supply hose to the pump is kinked

 Water lter is plugged. Check and replace if necessary

Pump Motor Runs; No Brew Pressure:

 Failed pump, needs to be replaced

 Brew Solenoid is stuck (can be caused by soap residue not fully ushed aer cleaning).

 Brew Solenoid has failed

 The line between the pump and the water supply has collapsed or is kinked

 Hose to the pump is kinked

 Water lter is plugged. Check and replace if necessary

 Water supply is inadequate

Readout for Brew Water Temperature Varies by a Few Degrees:

 The control must “see” the increment just above the set point before it sends a signal to turn o the

heang element. This will allow the electronics to show a reading just above the set point. The energy

from the heang element and the tube for the preheated incoming water are within 1” or 25mm from

the locaon of the temperature sensing probe in the coee 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 uctuate 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:

 Check to make sure the element breaker is ON (element switch is to the le). Zones will read low unl

the temperature in that zone reaches 175° F. Please allow 20-30 minutes to heat up inially.
