SU 2.0 Install Diagnostics - Power Supply Voltage Too Low/High

What is this?

This error is returned when the voltage reading is out of range (was read below 23v, or above 25v), during the install diagnostics test. We will add any other details here. 

Tools and Materials Required:

• #2 Phillips Screwdriver
• Multimeter

WARNING
	HAZARDOUS VOLTAGE (120 V / 240 V). CONTACT MAY CAUSE ELECTRICAL SHOCK AND INJURY.  DISCONNECT POWER BEFORE SERVICING.

Troubleshooting steps:

1. Power off the Bevi and unplug the power cord.  

2. Remove plastic top cover from the Bevi.

   • Open door.
     • If the door is not already open, touch “Open Door” in the upper right corner of the screen.
   • Remove the 3 screws from the base of the top cover lip
   • Lift the cover off and place to the side.

3. Remove the top and center panels from the back of the Bevi. 

   • Loosen the screws securing each panel..
   • Lift the panels up to unhook from the screws, and remove.
   • Place the panels to the side.

4. Inspect the 24v BUC Board power cable. 

   • Check the 24v power cable at the Power Module. 
     • Inspect connector and wires for any visible damage.
     • Verify the connector is fully seated and clicked into place.  
     • Gently disconnect, and reconnect the cable to the Power Module. 

• Check the 24v power cable at the BUC Board. 
  • Inspect connector and wires for any visible damage.
  • Verify the connector is fully seated and clicked into place.  
  • Gently disconnect, and reconnect the cable to the BUC Board. 

• Inspect the entire length of the 24v power cable between the Power Module and BUC Board.
  • Check for any cuts or damage in the wiring. 

5. Inspect the 24v Door Board power cable. 

   • With the door open, remove the restock board cover. 
     • Remove the single Phillips screw and gently remove the cover. 

• Check the 24v power cable at the Power Module. . 
  • Inspect connector and wires for any visible damage.
  • Verify the connector is fully seated and clicked into place.  
  • Gently disconnect, and reconnect the cable to the Power Module. 

• Check the 24v power cable at the Door Board. 
  • Inspect connector and wires for any visible damage.
  • Verify the connector is fully seated and clicked into place.  
  • Gently disconnect, and reconnect the cable to the Door Board. 

• Inspect the entire length of the 24v power cable between the Power Module and Door Board. 
  • Check for any cuts or damage in the wiring. 

6. Inspect the 24v Recircatator power cable. 

   • Check the 24v power cable at the Power Module. . 
     • Inspect connector and wires for any visible damage.
     • Verify the connector is fully seated and clicked into place.  
     • Gently disconnect, and reconnect the cable to the Power Module. 

• Check the 24v power cable at the Chiller. 
  • Inspect connector and wires for any visible damage.
  • Verify the connector is fully seated and clicked into place.  
  • Gently disconnect, and reconnect the cable to the Door Board. 

• Inspect the entire length of the 24v power cable between the Power Module and Chiller.
  • Check for any cuts or damage in the wiring. 

7. Plug in the Power Cord and power on the Bevi. 

   • The Bevi will restart.
   • Continue with installation up to the Install Diagnostic Test

8. Repeat the Install Diagnostic Test. 

   • ✔️If the test passes:
     • Reinstall the top cover on the Bevi.
     • Reinstall the Restock Board Cover
     • Reinstall the back panels.
     • Continue with installation.
   • ✖️If there continues to fail, continue to step 9. 

Additional Steps (Multimeter Required)

To troubleshoot beyond this point, a multimeter will be required to test voltage readings.

9. Test the 24v connections at the Power Module. 

   • Disconnect the BUC Board power cable.
   • Disconnect the Door Board power cable.
   • Disconnect the Recircatator power cable. 

10. Confirm the BUC Board power connector has 24v. 

    • Using a multimeter, confirm that the BUC Board connector measures at 24v
      • If the BUC Board connector measures <23v or >25v:
        • There may be an issue with the Power Module. 

• If the BUC Board connector measures at 24v:
  • Reconnect the Door Board power cable to the Power Module.
  • Retest and confirm the BUC Board connector still has 24v.
    • If the voltage changes, then there may be an issue with the Door Board. 
    • Contact Bevi Support at 866-704-2384.
  • Reconnect the Recircatator power cable to the Power Module.
  • Retest and confirm the BUC Board connector still has 24v.
    • If the voltage changes, then there may be an issue with the Recircatator. 
    • Contact Bevi Support at 866-704-2384.
  • If the BUC Board connector measures at 24v with both the Door Board and Recircatator connected to the Power Module, continue to Step 11. 

11. Confirm the Door Board power connector has 24v. 

    • Using a multimeter, confirm that the Door Board connector measures at 24v
      • If the Door Board connector measures <23v or >25v:
        • There may be an issue with the Power Module. 

• If the Door Board Board connector measures at 24v:
  • Reconnect the BUC Board power cable to the Power Module.
  • Retest and confirm the Door Board connector still has 24v.
    • If the voltage changes, then there may be an issue with the Door Board. 
    • Contact Bevi Support at 866-704-2384.
  • If the Door Board connector measures at 24v with the BUC Board power cable connected, reconnect the Door Board, and Recircatator 24v power cables to the Power Module.
  • Proceed to step 12.

12. Restart the Install Diagnostic Test.

    • ✔️If the test passes:
      • Reinstall back panels.
      • Reinstall the plastic top cover.
      • Reinstall the Restock Board Cover. 

✖️If the test fails, contact Bevi Support at 866-704-2384.
