Hot tub and spa pumps are designed to enhance circulation for the heater and filter and provide an extra boost whenever the spa jets are turned on high. They need to operate each day to ensure the water is heated and clean. For this reason, it is essential to make sure your spa pump is working efficiently. If something is wrong with the spa pump, no one will be happy – without water flow. There will be no heating, sanitation or filtration. So what are some of the common spa pump issues that can occur and render the equipment ineffective? Read on to know more.
Noisy spa pump
Have you been noticing some unusual grumbling, growling sounds or a sharp squeal whenever the hot tub kicks on? If the pump is growling, then the pump is struggling for water. Consider checking for clogs from the circulation system, then top off the water. Ensure the valves near the pump are open. If the pump is squealing, then perhaps the bearings aren't lubricated. If you continue using the pump, the noise will increase over time. Consider lubricating the bearings, and if the problem persists, you will have to replace the pump.
Dead spa pump
When you turn on the spa pump, but there is no action or noise, then it means that you are dealing with a faulty device. Luckily, there are several things you can do. First, check if other equipment items are powered and if the indicator lights are on. If they aren't, maybe the problem is a tripped circuit breaker. Examine the system fuse that's found in the panel. Consider replacing the fuse, and if it works, then you will know there was a short in the equipment wiring.
Another option would be to check the remote controller to ensure it isn't overriding the button or switch you used to turn on the pump. The switch may also be faulty, so be sure to hire an expert to examine it before you decide to give up on the device and purchase a new one.
If you have switched on the spa pump but its barely pumping, consider checking the filter. Perhaps the filter is dirty and needs to be cleaned. Then, check out the skimmer to see if there are obstructions. Some debris may have accumulated over time, making it impossible for the water to be pumped through. An air leak can also cause this problem, so get the pump examined for leaks when it is shut off.
