Hayward heater LO code persists!

Hayward heater LO code persists! H250FND Had an ignition failure code IF. Replaced flame sensor and ignitor. Didn’t fix it. Got a new main control board. Fixed the IF code but then got an LO code. Replaced the water pressure sensor and temperature sensor. Checked bypass mechanism which did have some debris, cleaned it. Continuity was tested and was good on all components. Still LO Code. Any ideas?
