Does the pump shaft turn? If NO, causes include: Something could be stuck in the impeller. Take the wet end apart • and remove obstruction. Bearings may have locked up. If so, you will need to replace the pump / motor assembly. Ice in the wet end. If the weather is freezing, you need to allow it to thaw then retry pump. If YES, causes include: Faulty capacitor. Change out the pump / motor assembly. Faulty motor switch. Change out the pump / motor assembly. Incorrect voltage. Make sure incoming voltage is correct |
| Pump makes a loud noise Does the pump make a grinding noise? If YES: If pump - motor assembly is older, replace the bearings or replace the pump / motor assembly The impeller could be broken. If there is no water flow into spa, check impeller. If the impeller is broken, replace it with a new one. There may be an obstruction in wet end. Foreign objects will grind against impeller. Open wet end and remove object. Does the pump make a squealing or high pitched sound? If YES: Check whether something is rubbing against the shaft. Inspect the shaft by the pump and remove any foreign objects. Check for incorrect voltage. Too high voltage can make motor run too fast. Check voltage and correct |
| Pump runs but water does not flow Causes may include: Pump is “air locked” See the Air Lock Section Gate valves are closed. Pull up to open all the way to allow water to flow to pump. Jets are turned off. Rotate jet inserts into the open position Dirty or clogged filter. Clean filter or replace with new cartridge. Impeller may be broken. Change defective impeller with new one. Clogged pump. During fall, leaves can clog the pump. Clean out the pump and impeller. Obstruction in the line. If the drain line gets clogged, the pump cannot get water. Check for obstruction and remove |
| Pump turns on and off frequently When spa is in standard mode, if the pump turns on and off frequently, the sensor is trying to maintain the spa’s temperature. The water temperature sensor is +/- 1 degree accurate. Switch to economy mode or check sensor for proper water sensor placement and insulation. |
| Pump runs Constantly The circuit board may have been changed out recently. One of the most common mistakes during a circuit board change out is a sensor that is plugged into the wrong place. If another sensor is plugged into the freeze sensor point, the pumps will run constantly until the wrong plug-in is corrected. Check plug placement and change to proper pin. |

If there was freezing weather during the delivery, the hi-limit / freeze sensor may have detected a possible
