Daikin mini split error codes
Daikin residential wall-mount and multi-split systems use Daikin's own code set, read from the remote controller's self-diagnosis rather than a display on the unit.
Covers: Aurora, 19 Series, Atmosphera, Emura, Quaternity, MXS multi-zone.

No code matches that. Check the characters (b and 6, 0 and o, and E and F are easy to confuse) or try another brand.
How Daikin shows error codes
Most Daikin wall units do not show the code on the unit; the operation lamp blinks. To read the code, point the remote at the unit, hold CANCEL (or Timer Cancel) for about 5 seconds until 00 shows, then press CANCEL repeatedly. Each press shows a code; when the unit gives a long continuous beep instead of two short beeps, the code on the remote is the stored fault. Units with a wired controller show the code directly. A and C codes are indoor-unit faults, E, F, H, J, L and P codes are outdoor-unit faults and protections, and U codes are system-level problems such as communication, power supply and refrigerant shortage.
Brands built on the same platform
These brands share a code table with Daikin because the same factory builds them, so their pages describe the same faults: Goodman.
