Panasonic air conditioner error code f90

The F90 error code indicates an issue in the outdoor unit’s PCB. Try resetting: switch it off and disconnect it for about 5 minutes, then reconnect and switch it back on. Also, it is advisable to ensure that your water pump is working properly. If it is blocked, it will continue to switch off, because it has difficulty draining excess water.
