Headers on hayward heaters are usually warranted for 10 years, except for freeze or chemical damage. You may want to contact a local warranty station to see if you can get it replaced under warranty.

Possibly failed keypad, or stuck key on keypad.
This product should be under full warranty, and installer should be called.
Hayward 350 product manual: Error codes start page 38 do not show Sb
However Sb error code shows on following manual as 'Keypad failure' or 'stuck key'... one of the keys is stuck longer than 30 seconds, but control will still function, replace keypad.
