Disconnected or damaged flowmeter
From Tech Sheet W16637623, p.35:
1.Disconnect power or unplug unit. Check connections at salt level sensor and at flowmeter. Use meter to check for flowmeter switch closed and salt level sensor.
2.Measure line voltage at the power cord terminal block. Expected: 120 VAC (L1 to neutral) or 208 to 240 VAC between L1 and L2 under load.
3.Inspect the cord strain relief and terminal block screws for signs of arcing or heat discoloration. Loose connections here mimic an intermittent power failure to the control board.
