This was googled: waves error codes
It showed a page in "images". Stated

Call a tech! Mini splits can be a troubleshooting nightmare! I think its a Fujitsu unit. It would help, and may save you some $$, to call around to find a technician who has worked on mini splits. And maybe find them a 1-800 # that is their tech support # before hand, so if the tech needs it, you have it. E4 is a vague description for a fault. Make sure you have cleaned air filters, cleaned o.d.coil (turn off power at breaker 1st). Changed batteries in remote. Work safe!
