The motor locked up because the thread is tangled. Remove the tangled thread before continuing the operation.

Brother electronic sewing machine code F1

Listed as main motor rotation failure.

Unplug the sewing machine and check the wiring connections on the power supply PCB and the main PCB assembly. If the problem persists, replace the power supply PCB. If the F1 code returns after replacing the power supply PCB, replace the main PCB assembly. Parts named: power supply PCB, main PCB assembly.

Brother electronic sewing machine code F2

Listed as button pressed continuously with power on.

The F2 code appears when the reverse/reinforcement stitch button, needle position button or start/stop button is stuck. Attempt to release the stuck button. If you cannot release the stuck button, replace it. If no buttons are stuck, replace the SSVR PCB assembly. If the problem persists, replace the main PCB assembly. Parts named: reverse/reinforcement stitch button, needle position button, start/stop button, SSVR PCB assembly, main PCB assembly.

Brother electronic sewing machine code F4

Listed as foot controller disconnected.

Plug in the foot controller jack if it's disconnected. If the foot controller jack appears damaged, replace it. Replace the foot controller if it's defective. Replace the main PCB assembly if the foot controller is connected and working properly. Parts named: foot controller jack, foot controller, main PCB assembly.

Brother electronic sewing machine code F5

Listed as dirty speed sensor.

Unplug the sewing machine and check the timing shutter wiring connection on the main PCB assembly. If the wiring connection is okay, clean the timing shutter. Replace the timing shutter if it doesn't work after you clean it. If the problem persists, replace the main PCB assembly. Parts named: timing shutter, main PCB assembly.

Brother electronic sewing machine code F7

Listed as speed VR disconnected.

Unplug the sewing machine and reconnect any loose wires on the SSVR PCB assembly and the main PCB assembly. If the wiring connections are okay, replace the SSVR PCB assembly. If the problem persists, replace the main PCB assembly. Parts named: SSVR PCB assembly, main PCB assembly.

Brother electronic sewing machine code F8

Listed as power supply failure.

Unplug the sewing machine and check the wiring connection between the power supply PCB assembly and the main PCB assembly. If the wiring connections are okay, check the output voltage from the power supply PCB. Note: You should check this output voltage only if you're completely confident in your technical ability to safely perform this test. Follow electrical safety guidelines when checking this voltage. Wear electrical safety gloves when conducting the test. Unplug the sewing machine immediately after completing the test. Check for 5 VDC between pins 2 and 3 on PCB assembly connector CN201.

Check for 30 VDC between pins 4 and 3 on the same connector. If voltage on those pins is incorrect, replace the power supply PCB assembly. If the voltage is correct, replace the main PCB assembly. Parts named: power supply PCB assembly, main PCB assembly.

Brother electronic sewing machine code F9

Listed as main PCB assembly failure.

Replace the main PCB assembly. Parts named: main PCB assembly.
