You had a long day at work and came home to relax. The first thing that came to your mind is a nice relaxing soak in your hot tub. So you rushed to your backyard and turned everything on, eagerly waiting. However, what came next was unexpected. The pump of your hot tub is humming uncontrollably and you have no idea why. There might be some water in a place that there shouldn’t be, or there might not be any noticeable problems. Either way, if the humming gets progressively more loud, you know you are not going to have a nice soak. Despite your initial disbelief, this humming problem is not that uncommon. In fact, we are writing this post to inform hot tub owners about the probable cause and remedy that they could use to stop this incident.The most common problem that could occur when a hot tub hums is an air lock in the hot tub. Note that if a spa has an air lock problem, the topside control panel may show an error message. This occurs after improper draining process which then leads to miniscule air pockets getting trapped inside the hot tub pipes. Air pockets prevent hot tub pump from pushing the water properly and eventually, it could lead to the pump to break. These air pockets or air lock need to be purged before your pump can work again. One of the best ways to do this is to loosen the pump union is with channel locks or large pliers to release the trapped air lock. You could also simply do this using a simple hammer and screwdriver; however, be careful not to damage the pipes and not to over tighten the union by applying too much force.
Another common issue is an increasingly noisy hum from your pump. This issue could be derived from many different reasons which are not as easily detectable as the air lock problem. A plausible situation is that the bolts, screws, or base of your tub pump are loose due to the vibration of the spa motor. If this is the case, then you will need to remove the basic parts of your hot tub and listen to the source of noise. Once you find it, you can then tighten all the parts using a pliers. It is also possible that your pump might have caught a debris or is worn out. Depending on the severity of the situation, you could either hire a professional to replace some parts or replace the entire pump as repair might be extensively more expensive.
