Hi all the experts!

I am writing to you, because nobody official in my country will help.
All they can offer me - is to buy new one - and that is expensive.

I have Daikin RXS35 BVMB Outdoor model.

Only fan is working.

When running test mode it works like this:
Fan starts and works for around 30 sec.
Then compressor starts and it works for around 5 sec. I can hear the pump working.
Then it shuts off.

When tested I get L5 error.

What to do now?

I am not really electric handy, but do know the basics, can weld and do stuff.

Please give me some instructions on how to proceed to repair the device.

Thank you!!!
Mitja
