How to Troubleshoot a Spa Pump Problem

Spas have a number of different parts that heat and move water through their systems. The pump is responsible for moving water through the filter, heater and back into the unit through the jets inside the spa. Because it constantly works to keep the spa environment comfortable for its users, a variety of issues can restrict water flow and cause problems in the unit. While broken or damaged pumps need a professional for repairs, you can try some simple troubleshooting steps to help get your spa back in good working order.

Pump issues can result in low water temperature and other problems in your spa.
  1. Check the water level in the spa. Water that is below the filter level will not cycle water through the pump system properly.

  2. Clean or replace the filter. Much like low water levels, the pump cannot cycle water if the filter restricts water flow.

  3. Unclog the water intake valves inside the spa. These valves can become clogged if the water is dirty, which restricts water flow to the pump and reduces jet output.

  4. Review the mode on the control panel. Spas often have multiple modes, with one or two meant to economize on the energy usage of the spa. Using the spa when set in an economy mode may result in lower water heat and less water movement.

  5. Check the electrical connections to the spa. Pumps that are inoperable may just need to be reset. You can do this by turning the ground fault circuit interrupter (GFCI) off then on, which is located in an enclosure near the spa. The GFCI is a safety device that is designed to prevent electric shock.
