Tablet Error 104 - Supply Voltage is Too Low

Error 104 indicates that the Mixmate hardware is sensing a drop in power. While the system may still be running, low voltage often leads to erratic behavior, communication failures, and improper valve operation.

Why am I getting this error?

You will receive Error 104 when the machine detects that the voltage has dropped to a critical level (typically around 12.3V or lower). This is a warning that your battery lacks the "push" required to operate heavy loads like pumps and valves.

If this isn't addressed, you will likely see other secondary errors as individual components fail to receive enough power to function correctly.

Understanding Voltage and Battery Health

Voltage alone doesn't tell the whole story; capacity is just as important. A battery can show "good" voltage when idle, but crash as soon as a load is applied if it has no capacity.

VoltageBattery Status
11.7V and belowDead. The battery cannot operate the system.
11.8V to 12.3VVery Low. Approximately 25% capacity. This is where warnings trigger.
12.7V to 13.8VMaintaining. This range holds the current charge but does not charge the battery.
14.0V+Charging. This is required to add capacity back into the battery.

Note: If your charger never reaches above 13.8V, you are never truly recharging the battery. Over time, the battery will lose capacity and fail under load even if it shows "13V" on the screen.

Troubleshooting and Resolution

1. Initial Power Check

  • Charge the Battery: Connect a high-quality charger to the system immediately.

  • Inspect the Battery Disconnect: Check the screws on the back of the disconnect switch; they can vibrate loose over time.

2. Verify Grounding and Connections

  • Ground Wire: Check the connection between the Mixmate frame and the Power Module.

  • Power Lug: Check for corrosion or loose nuts on both sides of the Power Lug on the frame.

3. Check Fuses and Circuit Breakers

  • Pro Inductor: Check the two 15 amp fuses in the black fuse panel (top rear of unit).

  • Fusion Inductor: These use auto-resetting circuit breakers; check for heat or "tripped" signs.

  • External Starter: Check the in-line fuse located inside the housing.

4. Test the Power Module (White Box)

Remove the cover of the white Power Module box and test the wires labeled on the circuit board with a multimeter:

  • 12V IN: Should match your battery voltage.

  • OUT (1 and 2): Should match battery voltage when the disconnect switch is ON.

5. Visual Indicators

  • Ensure the Stack Valve lights are on.

  • Check that the Internal Valves in the inductors are lighting up when activated.
