Why is the overload tripping on my Pentair Hydromatic Control Panel motor starter?
- SSamuel ScottJul 27, 2025
If you're experiencing nuisance tripping of the overload on motor starters or circuit breakers of your Pentair Control Panel, several factors could be at play. Start by checking the pump's amp draw with an amp probe and compare it to the nameplate amps on the pump. The impeller might be locked up due to excessive debris or solids. Also, there may be a possible motor failure due to a fault in the windings, or the pump may be miswired to the terminal block. For three-phase systems, check for voltage and current unbalance, and connect leads for the lowest percent of current unbalance. On single-phase units, check connections and start components.
