There are only a few things that can go wrong with a spa pump. The inlet or outline line could become clogged outlet. The pump may leak around the base, or it may not operate at all. Any malfunctions other than these should probably be attended to by a trained professional, but these problems may have simple solutions.

Step 1: Diagnose the Problem

If your spa pump is leaking or or not flowing, examine it to find out what the problem may be. If the intake is not working, the problem might be a clog. Repair it by simply removing the obstruction. Similarly, there is no need to remove the pump if problems are caused by objects that have become jammed in the jets.

Step 2: Disconnect the Power

Do not perform any repairs on a hot tub pump until after the power has been disconnected. This may involve a circuit breaker or a separate box mounted near the pump. Never work on water-moving devices while the electricity is running.

Step 3: Remove the Pump

Remove the spa circulation pump. In most cases, this removal entails removing 4 to 8 bolts, but some models use other mounting methods. If you have trouble getting a bolt to turn, spray it with WD-40 or some other penetrating fluid, and allow the bolts to set for 5 to 10 minutes.

Step 4: Clean Connectors

Clean the connectors thoroughly. Check any washers or gaskets used in the connectors or the pump mounts. Replace worn or damaged gaskets. For a tighter seal, place a drop of oil on the washer or filter, and rub it into the entire surface.

Inspect the pump for any foreign objects that have gotten lodged inside it. Even a small piece of plastic could cause the pump to jam, rendering it ineffective.

Step 5: Remount the Pump

Carefully mount the pump back on the motor. If there is a gasket between the pieces, make sure it is properly in place before installing the bolts. To install bolts, snug each one in a clockwise direction, and then start over and tighten each bolt down, in the same pattern. This helps to give you an even, consistent seal.

Step 6: Restore Power and Test

Restore the power to the motor and turn it on. If all has gone well, the leaks will be fixed. If you still have leaks, repeat the process. If leaks are still present after a second attempt, you may need the services of a plumber.

Step 7: Motor Problems

If the motor does not operate, your problem is not with the pump. Unless you have moderate experience in household electrical procedures, you should leave repairing a faulty electric motor to a trained technician. You can even remove the motor and take it to a repair center.
