Haier air conditioner error codes
Haier washers use two sets of codes: newer front-loaders show Err codes such as Err1 or Err2, while top-loaders and older models show short codes like E1 or FA. Haier air conditioners show E codes for indoor-unit faults and F codes for outdoor-unit faults, and FL on portables when the water tank is full. The same code can mean different things on different appliances, so match the code and appliance exactly.
