I would first check the condensate drain pipe. This can be done by blowing back into the drainpipe from outside. Not to worry it is not dirty or dangerous. Also make sure that your air filters are clean.
SOURCE: The timer light flashes twice about every 15 seconds
This may mean that the filters may need to be cleaned. According to service manual the unit has a "Serial reverse transfer
error at start up operation". Call fujitsu for service if the fault cannot be rectified.

Please specify the make and model of your unit.
If this is a LG inverter model.
The six flashes of the indoor unit light indicates a CH 06 alarm.
This alarm state indicates that the indoor unit pipe temperature sensor has measured a temperature out of range or the unit is protecting itself from this low temp state. Indoor unit coil temperature to low. Should it have reached a temperature of -5°C for longer that 30sec it will switch the machine off.
It could indicate that the unit refrigerant charge is too low or the sensor has gone out of calibration.
It should measure 5kΩ @ 25°C

If it s a 230v5 unit switch the power legs for the air handler unit. If that does not work, make sure the comm wires are 18gauge shielded cable.
