Product details
Governing power and control for the HiZero Bionic Mop F803 and F500, this main circuit board (PCBA, part #3400001401) coordinates the motor, pump, and sensor signals that run the cleaning cycle.
A damaged main board can prevent startup, trigger intermittent shutdowns, or scramble normal operation while individual components remain intact. Fitting the correct board reestablishes stable power management and predictable control.
- Fits: HiZero Bionic Mop F803, F500
- Part: main circuit board / PCBA #3400001401
- Function: central control and power coordination
- Tip: label each connector before removing the old board
The board mounts inside the body with several harness plugs. Disconnect the machine from power before you begin, and verify the F803 or F500 model on the unit so the replacement board matches its wiring.
