has anyone else had problems with Fuj wallmount asya24lcc

I have had 2 where from time to time the I get fault code lights 5flash/2 flash which indicate a high pressure problem. Suction pressures, performance, and temparatures are all normal prior to malfunction, Turning power off, leave, and turn on again, eventually rests the system.

One system is 15 mtr run, the other 5 mtr run, both have two brazed joints (connection to indoor unit, flares cut off) done with nitrogen.

gas charge has been recovered and new charge reweighed back in in both cases.

If this is a known problem, is there a solution and has it been rectified on the next series of unit. ( A year ore so ago Fujitsu went out of stock of this model, and after a few weeks of no stock released a new asy24a where as far as we can tell the outdoor unit was incompatable with the previous... ie as far as we know if an outdoor unit a year old now gives this fault, we havent got the option to replace the complete outdoor anymore)
