It's definitely the nanoe-G. Can someone else please confirm if they notice a difference with nanoe-G on & off? It's pretty noticeable but disappears when nanoe-G turned off from remote.
Thanks for posting this. I also have the CS-E15PKR and noticed that noise recently. I've switched off Nanoe and the noise disappeared immediately. Put it back and the noise came back again. I will see about getting it serviced.
Did you happen to find a fix (other than turn it off)?

simply leave it off.
its basically a modified ionizer which generates ozone, which generates pollution (which research has proven). it actually gives me a sore throat from breathing it in, i have a few of them. so overall its just a gimmick that causes more problems than it solves. sadly since covid started there is a huge growth in this sort of crap. avoid "active cleaners".
quebec: Anyone else have Panasonic heat pump. Mine had this annoying hissing nose when starting up and then the noise goes away when it’s running. Sounds like has moving. Hopefully not a leak otherwise all gas would have leaked by now isn’t it? Have checked other brands at friends places no such sound. Also had a look at similar model running at someone’s place and couldn’t hear this sound. I can record it and upload if that helps.
I would say it is perfectly normal.
To me it sounds like they control the compressor by closing a valve and allowing it to "pump down" causing the compressor to stop when it detects "low gas" on the pressure switch
The hissing sound will be when the valve opens and the gas equalises around the system, making the "low gas" pressure switch to change state and allow the compressor to start up.
Sometimes on a split system manufacturers specify a minimum pipe length, usually to stop gas noise. Usually about 2.5 metres minimum which is about a basic back to back install length.
My mate has Panasonic heat pumps, about 4 years old. I house sat for them and the 2.5 kW unit in their bedroom was noisy. My mental note was never to buy a Panasonic. Its pipe length was about 3 metres.
