Error on split-unit aircon

[GodAtum]

I have a split unit aircon that is giving an F5 error. According to the troubleshooting guide this means "Malfunction of outdoor module". But no guidance on how to actually fix it.

The power is OK, the indoor unit is OK, but the fan on the outdoor unit is not spinning. No cables or pipes look like they are broken.

Any help is greatly appreciated as obviously I cannot get a professional out to fix!

It's an eIQ-18WMINVB 18000 BTU Black Hitachi. Yes I've tried powering it off at the wall socket.

Being a generic brand there is not much trouble shooting guides out there.

One option if your happy to do this (your unit look like its a inverter model) is to unplug the inverter board comms cable and condenser fan motor and see if this detects any other error messages.

Also disconnect the electronic expansion valve.

*** ONLY DO THIS IF YOUR HAPPY ***

I had a poke around but don't think I'm qualified enough to do this
