BUCB Temp Too Low/Too High (CT 1.5 Install Dx Error)

Updated

Required Tools

  • Phillips Screwdriver (#2)

Troubleshooting Steps

Task 1: Repeat the Diagnostic Test

  1. Verify water and CO2 are turned off, and filter is NOT installed.
  2. Restart the diagnostic tests to see if it passes on the second attempt.
  3. If the test continues to fail, power cycle the Bevi via the power switch on the front of the chiller.
    • Navigate back through the installation steps to the Install Diagnostic step and repeat the test.
    • If the test continues to fail, continue to Task 2.

Task 2: Confirm proper ventilation.

  1. Verify that the chiller has been installed to the proper ventilation specifications.
  2. If the cabinet millwork has not been completed to spec, the chiller should be completely removed and ventilation holes need to be drilled.
  3. If ventilation holes have been drilled, verify the tabs of chiller ventilation grate are properly located into the holes so the chiller is sitting flush on the cabinet base.
  4. If ventilation is to spec, continue to Task 3.

Task 3: Power Off the Bevi.

  1. Power off the Bevi using the power switch on the front of the chiller.
  2. Disconnect the power cord from the back of the chiller.

Task 4: Remove the chiller from the cabinet.

  1. Carefully lift the front of the chiller so the locating tabs on the bottom can come up and out of the ventilation holes.

  2. Slide the chiller forward so the front hangs over the edge of the cabinet.

  1. Remove the red locking clip and disconnect the 3/8” water supply line from the back of the chiller.

    • This step may not be necessary if there is enough slack on the water line to fully remove the chiller without putting tension on the tubing.

  1. Lifting from the front and the rear grab handle, carefully lift the chiller out of the cabinet and place on the floor.

Task 5: Remove the PCB panel.

  1. Using a #2 Phillips screwdriver, loosen the two screws securing the PCB panel on the left side of the chiller.
  2. With the screws fully loosened, lift the panel to release the lower locating tab and remove.
  3. Place the panel to the side.

Task 6: Inspect the PCB Fan Connection.

  1. Locate the PCB Fan connection on the BUC Board.
  2. Inspect the Fan cable.
    • Confirm that the cable is connected and fully seated.
    • Inspect the wires and connector for any visible damage or loose pins.
      • If there is any damage to the cable or connector, please contact Bevi Support at 866-704-2384.

  1. Gently disconnect, and reconnect the Fan cable.
    • There is a lock latch on the connector that needs to be depressed to disconnect the cable.
    • When reconnecting, ensure the connector is fully seated and clicks into place.

Task 7: Reinstall the Chiller.

  1. Reinstall the PCB panel.
    • Take care not to pinch any wiring in the panels.
    • Ensure the locating tabs slot into place
    • Tighten the screw to secure the panel.
  2. Reconnect the chiller power cord.
  3. Carefully lift the chiller into place in the cabinet.
    • Ensure the locating tabs on the bottom of the chiller fit into the ventilation holes and the chiller sits flush on the base of the cabinet.
  4. If it was disconnected during removal, reconnect the 3/8” water supply tube.
    • Ensure the tubing is fully seated into the push to connect fitting.
    • Reinstall the red locking clip.
  5. Power on the chiller.

Task 8: Repeat the Diagnostic Test

  1. Once the Bevi starts up, continue through the Install Wizard back to the diagnostics step.
  2. Rerun the test.
    • If the test passes, continue with Installation.
    • If the test continues to fail, there may be an issue with the PCB fan or BUC Board.
