A 1-Blink Error on the Power Module is a critical hardware alert indicating that the system has experienced a severe power drop, causing it to shut down to protect the electronics.
If you see the LED on the Power Module blinking once every 5 seconds, the machine has detected that the voltage dropped below approximately 11 volts.
At this level, the machine cannot function properly. Unlike Tablet Error 104 (which is a warning), a 1-Blink Error is a hard stop. You must reboot the Mixmate machine to clear this error after the power issue has been addressed.
The most immediate fix is to get a charger on your battery. However, you must understand the difference between Voltage and Capacity:
| Voltage | Battery Status |
| 11.7V and below | Dead. The battery cannot operate the system. |
| 11.8V to 12.3V | Very Low. (25% capacity). Low voltage warnings trigger here. |
| 12.7V to 13.8V | Maintaining. Holds current charge but does not add capacity. |
| 14.0V+ | Charging. Required to add capacity back into the battery. |
Warning: If your charger never reaches above 13.8V, you are not adding capacity. A "weak" battery might show 13.5V while charging, but the moment a pump or valve draws power (load demand), the voltage will "crash," triggering the 1-Blink error.
Battery Disconnect: Check the screws on the back of the disconnect switch to ensure they haven't vibrated loose.
Grounding: Inspect the ground wire connection between the Mixmate frame and the Power Module.
Power Lug: Check for corrosion or loose connections on both sides of the Power Lug on the frame.
Pro Inductor: Check the two 15-amp fuses in the black fuse panel (top rear of unit).
Fusion Inductor: Look for tripped auto-resetting circuit breakers.
External Starter: Check the in-line fuse located inside the housing.
Remove the cover of the white Power Module box and test the labeled wires on the circuit board with a multimeter:
12V IN: This should match your battery's actual voltage.
OUT (1 and 2): Should match battery voltage when the disconnect switch is in the ON position.
Verify that power is reaching the rest of the system:
Are the Stack Valve lights on?
Do the Internal Valves in the inductors light up?
