Troubleshooting/Fault Codes This guide will cover only those problems with the VSC and Motor. All other pump problems including seals, gaskets, impellers, etc along with priming problems are addressed in the owners manual. Code/Fault Indications Drive Error! Drive is Overheated Drive Error! PFC Circuit Hi Drive Error! Drive Overload Indicates that the internal components of the drive have become overheated. Motor airflow path should be checked. Follow disassembly/assembly procedures (pages 32-37). Clear all debris from the heatsink on the bottom of the drive (page 36). Check fan and shroud for blockage. If error still occurs, replace drive. Indicates internal drive voltage is too high. Check incoming line voltage (page 4) and verify that it is within +/- 10% of 230 VAC. If line voltage is correct and error still occurs, replace drive. Indicates that the motor is drawing excessive current. Check impeller, diffuser and shaft seals for issues. If there are no issues remove the Blue, Black and Red wires (page 4) from the drive and check each motor lead to ground. There should be no continuity. Check continuity from lead to lead. Ohms readings should be between 0.5 and 1.0 ohms max. If any of these readings are outside limits, replace motor. If they are within range, replace drive. Page 42
