What to do if my Pentair STA-RITE DS3HG-01 motor will not run?

  If your Pentair Water Pump motor isn't running, there are several potential causes. First, ensure the disconnect switch is turned on. Next, check the fuse and replace it if it's blown. A defective starting switch could also be the culprit, so consider replacing it. Lastly, inspect the wiring at the motor for looseness, disconnections, or incorrect wiring. Refer to the wiring instructions and tighten all connections. Be cautious of capacitor voltage and discharge the capacitor with an insulated screwdriver if necessary. If unsure, consult a qualified electrician.

Why does my Pentair Water Pump motor run hot and the overload keep kicking off?
- C
  Corey FerrellAug 23, 2025
  If your Pentair Water Pump motor runs hot and the overload trips, it could be due to incorrect wiring. Refer to the wiring instructions to ensure it's properly connected. Another potential cause is low voltage. Check with your power company and consider installing heavier wiring if the current wire size is too small.

How to fix a Pentair STA-RITE DS3HG-01 that does not deliver water to full capacity?
- C
  Craig HensleyAug 31, 2025
  If your Pentair Water Pump isn't delivering water to its full capacity, a leaking foot valve could be causing a loss of priming, so replace the foot valve. If the water level in the well is more than 25 feet below the pump's suction point, you might need a deep well jet pump. Corroded or limed steel piping (if used) can cause excess friction; replace it with plastic pipe where possible, or with new steel pipe. Also, ensure that the offset piping isn't too small; use larger offset piping if needed.
