My Jandy LRZ shows on the screen " Universal Controller U1 FW Rew: 1.8". Nothing works !
Not sure if I need to replace the "universal control power interface part # R0470200 (about $150), or universal control user interface part # 3008800 (about $500).
Any suggestions would be appreciated very much as I would hate to throw good $$$$ after bad $$$.
Thank you in advance.
