Rheem pool spa heat pump fault codes F51, F52, F54, F55

(Miramar beach, fl)

Rheem pool/spa heat pump digital Model #: M8350TI-E serial#: W151416637 started to get cold here in Florida turned heat pump on last week everything worked fine until yesterday.
Trying to heat spa only set temp for spa @ 75 degrees. Actual water temp 49 degrees. Light comes on when heater is heating water. Feel water coming out of jets warm!/ hot! Yeah! but Then after 5 minutes light goes off. Fault code pops up. I'll hit the set button on control panel heater kicks on, light on showing water being heated, feel water outta jets warm/ hot. This continues until I get tired of going outside every 10 minutes or so. What are the fault codes? How to fix? Heat pump only year old.

FS not F5 NEW
by: Anonymous

Unit is in the defrosting cycle which means that the fan is operating but the compressor has been stopped.
A numerical digit behind the FS indicates how many times the unit has switched into this mode

Same here NEW

Model M8350TI-E
Seems to start ok on either pool or spa setting and red heating light on. Then after a few minutes, the heating (red) light goes out and I get either F51, F52, F54, F55 code show up? Tried everything I can think of.
