My 5 year old H300FDN Hayward pool heater doesn't start with "bd' error (both lower case). Although this error code is not mentioned in the manual, I've completed all diagnostics from it (checked fuses, white connectors, voltage, etc) and believe I need to replace ICB next. Figured I'd check with the forum before purchasing a new part. Has anyone come across the same issue by any chance?
