Turbulent Brew Time Sequence Components; Press-Out Sequence Components - Bunn trifecta Technical Training Manual

Turbulent Brew Time Sequence
After the fill sequence is complete, air enters the brew chamber around the check valve to agitate the brew
substance. The force of air through the turbulent pump is adjustable along with the pulse duration.
Troubleshooting Components
Each of these components can be tested during the troubleshooting process.
• Brew Chamber
• Brew Cup
How to Troubleshoot the Turbulent Brew Time Components
Note: Check to make sure that the brew chamber is in position and locked.
Step 1: Enter the level 1 programming menus by pressing and holding both arrows for approximately 3 seconds until
the display screen reads "Recipe Changes" "Enabled - Locked".
Step 2: Scroll to the "Service Tools" menu and select "Yes" to enter this option.
Step 3: The display screen will now read
Step 4: Scroll through the menus until the display screen reads "Rinse Water".
Step 5: Select "On" to fill the brew chamber 1/3 full.
Step 6: Select "Next" until the display screen reads "Bubble Air Pump".
Step 7: Run an output test for the bubble air pump by selecting "On". During this time, air should be entering the
bottom of the brew chamber.
No Bubbles During Output Test
• Replace the turbulent air pump.
• Replace the control board.
No Bubbles During the Brew Process
• Check the turbulence power setting in the brewing parameter menus to see if it's Off or set at low power.
• Follow the procedure for testing the turbulent air pump in "Service Tools".
• Check the o-ring on the bottom of the brew cup.
• Replace the turbulent air pump.
• Replace the control board.
Press-Out Sequence
After the fill and turbulent brew time sequence is complete, the brewer will close the vent valve to the brew chamber
and turn on the press-out air pump to begin the process of pressurizing the brew chamber. Pressure coming from
above the sprayhead cone will press the beverage out through the center of the check valve and into the
receiving container.
