 AB Repair PIC fault code list. These only apply to our PICs.

Mk4.0 Round

This is our original code and does not have any extra fault codes added.

Mk4.2 Square v1

LED Status Buzzer Status Fault Reason for fault code
on (no flashing) Silent Check IC soldering or R1 or D2 is faulty. The IC can not detect the line frequency
Yellow (no flashing)  Beeping 240v mode with thermistor disconnected, faulty thermistor or to cold. This is also for testing the voltage detection is working.
Red (no flashing) Beeping 110v mode with thermistor disconnected, faulty thermistor or to cold.  This is also for testing the voltage detection is working.
Flashing  red and yellow Silent   IC is on the wrong version of PCB (it is for a round buzzer pcb)
LED wrong colour
while running
 

Some versions of the switch side PCB have the LED fitted in the opposite direction.

Switch the 2 LED wires around on the switch side PCB

 
    Too hot or too cold. Check R3

MK5 Round and Square v1

LED Status Buzzer Status Fault
on (no flashing) Silent Check IC soldering, R1 or D2 is faulty
on (no flashing)   Beeping 240v mode with thermistor disconnected, faulty thermistor or to cold. This is for testing the voltage detection is working.
off Beeping 110v mode with thermistor disconnected, faulty thermistor or to cold. This is for testing the voltage detection is working.
Flashing  Silent IC on wrong version of PCB 
    Too hot or too cold. Check R3

Universal IC V1

LED Status for mk4.2 square and all mk5 LED Status for mk 4 round Buzzer Status Fault
on (no flashing) same Silent Check IC soldering, R1 or D2 is faulty.
on (no flashing)  Red (no flashing)  Beeping 240v mode with thermistor disconnected, faulty thermistor or to cold. This is for testing the voltage detection is working.
Off  Yellow  (no flashing)  Beeping 110v mode with thermistor disconnected, faulty thermistor or to cold. This is for testing the voltage detection is working.
Slow flash same Slow beep IC has gone to sleep because it has detected a heater fault at startup.
on (no flashing) same Slow beep IC has gone to sleep because it has detected a heater fault while running.
