Remove probes and bend straight or replace with new
probe(s)

Check line voltage first. Check AC voltage across
load terminals on Liquid Level Control. If voltage is

120 plus or minus 10%, replace motor or motor wiring.

Check line voltage first. If AC voltage across load

terminals is not 120 plus or minus 10%, replace the

Liquid Level Control Board.

Verify water pressure leading into pump inlet is 40 psi
minimum with pump running.

Pump will not run but

tank appears to be

always full.

Common Lead (Green) shorted out to
Red wire (High Probe)

Verify Green and Red wires are not touching.
