Heater error code

[NYPOOL]

Hello,

Have viewed site for a few years and decided to join so i can ask questions instead of looking for posts with similar problems I'm experiencing.

Opened pool last Saturday and heater showed LO error Code. Pool service company couldn't get it going referred me to heating company. Had to replace water pressure switch.

Today heater starts up ignites and then i get SB error code. Heater is running but can't use keypad.

Any advice or ideas are appreciated. I am pretty handy and can repair and troubleshoot if pointed in right direction.

heater is a Hayward H200FDN

Thanks

Turn off the power for 5 minutes or so and then turn it back on. It worked for me.
