This error appears when the pump determines that the main voltage feed has
dropped below 185VAC:
Shut off breaker supplying EcoStar with power
for at least 2 minutes, then restore power. Open
wiring compartment and go to step 4B.
Verify pump power
With the pump idle, check voltage on mains
connector. If voltage is above 200VAC, go to 4C;
if below 200VAC, correct supplied power.
