Remember that each hot tub is different, and the best way to find out how to remove hot tub filter pieces and change the filter in your specific model is to refer to your instruction manual.

Tub Filter Troubleshooting
It’s inevitable that at some point during the course of your hot tub ownership, you’re going to run into some kind of trouble. Whether you find your hot tub not filtering, discover that the water isn’t getting hot enough, or even notice that the jets aren’t working properly, the filter is always a good place to start troubleshooting. The following tips will help you figure out whether or not the problem with your hot tub is really focused on your filter or not.
- If the filter isn’t working, your water flow may be limited. This is usually because something very large is blocking the filter and keeping water from entering the hot tub properly. Clean the filter well or replace the cartridge to remedy this problem.
- If your water isn’t getting hot enough, this could still have to do with your filter. There are a lot of other problems that could cause the water not to heat properly in your hot tub, but the filter is one of them. Keep it clean and replaced as necessary to be sure water is moving the right way through the hot tub.
- You might find that your water doesn’t seem to be filtered at all when it reaches your hot tub. It may have a lot of debris in it, or it might be too hard on your skin while you’re soaking. If this is the case, your filter isn’t working right and should be replaced. In most instances, this just means replacing the filter cartridge. Rarely, the entire filter basket might need to be replaced. You can order this replacement part from the store where you purchased your hot tub, or directly from the hot tub manufacturer.
- One of the biggest problems you can run into with your hot tub is the filter not working at all. This usually means the pump is shot. This may mean that you need to carefully remove all the air from the pump before you use it, or that there’s debris caught in the pump lines. It may also mean the jets and other components of your hot tub need to be cleaned to remove blockages. In a worst case scenario, parts of the pump may be broken and might need to be replaced.
Other Tub Filter Problems
Hot tub owners must deal with a variety of different problems that might come up during the life of the hot tub. Below are just a few of the issues you might discover while learning how to better maintain your hot tub.
- Poor heating. Heating your water is a very important part of having a hot tub. Without hot water, you only have a cold bath on your hands. In some cases, water in a hot tub takes much longer than it should in order to heat up properly. It might only get lukewarm at best, or it might take fifteen or more minutes to really get hot enough to enjoy. In other cases, the water might not heat up at all, leaving it completely cold no matter how long you let it try to heat. In both of these instances, the thermostat is the most likely culprit. The filter or the insulation in the hot tub may also be to blame.
- Low water quality. Unfortunately, depending on where you live, you can’t do a lot about your water quality. However, you can work to add the right chemicals and treatments to your hot tub water to make it work correctly.
- Cracked covers and frames. When left out in the elements, your hot tub’s cover and frame will slowly weaken and become more prone to cracks. If this happens, the hot tub may not function properly, and it may stop working altogether. It’s in your best interest to be sure you cover your hot tub when you aren’t using it.
- Broken pumps. A broken pump will mean that your hot tub isn’t going to work at all. You need the pump to function in order to draw water into the hot tub. If it stops working, it will be expensive and difficult to replace. Unless you notice obvious signs that a pump is broken, like smoke coming from the pump, try all your other repair options first.
Of course, some of the biggest problems that have to do with hot tubs revolve around the filter.
