3/4 hp motor with a proven 3/4 hp impeller and 238 volts under load, inground pool, clean filter, plenty of water available to suction end. Pressure gauge not working. Recent refitting of chlorine generator allows for possibility something got into return line to pool which may be causing a restriction. Would that explain motor drawing 7.5 amps vice 5.9 nameplate and thus heating up and cutting out on thermal overload. All valves have been disassembled and found clear.

Any other ideas as to what is eluding us.


Thanks, PMD
