Hot Tubs Problems and their Solutions.

Unfortunately, just like any other equipment made by human beings, a hot tub can also inevitably go wrong. But do not be panic because here, we will look at some very prevalent Hot Tubs Problems and their Solutions.

  1. My Hot Tub Is Not Heating Up:

There will be no importance of having the hot tub if it is not heating up. It will be just like a tub filled with cold water. Here are three common Hot Tubs Problems and their Solutions that prevent them from heating up.

Circulation Issues:

Is it taking an eternity for your water to heat up? Is your hot tub heater always turning off? You should examine your water flow since this could be the source of the problem. The amount of water passing through your heater is not as much as it should be. Most heaters are intended to cut out in these situations as a safety precaution so that they do not burn out.

To resolve this issue, follow these steps:

  • Examine the Water Level: 

First and foremost, double-check that your hot tub has enough water. If your hot tub is kept outdoors for an extended period, water will evaporate. If the water levels get too low, fill the tub with more water so that adequate water gets through your heater. Eventually, the spa skimmer will begin vacuuming in the air rather than water, which will travel through the heating element. Consequently, the heater will shut down, causing the breaker to trip.

  • Any airlocks in the pumps should be released:

If you recently replaced the water in your spa and your system suddenly stopped heating, there might be some air trapped in the pipes. This can only imply one thing: it is very little or no water flowing via the pipes and through the heater. To release the air pressure, fully open the jets and turn off the heater. Turn on the jets and allow the water to run until air bubbles appear in the jets. Check to see if the water heats up after reconnecting the heater. Are you unsure how to proceed? If you contact any hot tub troubleshooting expert, they must be able to help you with this.

  • Clear the filter:

So, your spa’s water level is OK, and thus no air is blocked within the pipe, yet your tub will not heat up? Try hot tub filter cleaning. Your filter’s job is to remove dirt and other contaminants from your spa’s water. Every time you use it, additional particles from the water are sucked up. So, if you use the filter for an extended period without cleaning it, it may become clogged, restricting water flow that can create interference with your hot tub heating.

  • Examine the Pressure Switch:

If your water is not yet heated after cleaning or changing the filter, you should examine the pressure/flow switch. This is often linked to the heater’s tube. To check this out, it’s better to approach a spa troubleshooting specialist.

  • Determine if the spa pump is operational:

If you have tried everything and still have a water flow fault, the issue could be with your pump. Might be possible that it is not effectively pumping the water across the tub, causing the flow to halt or limit, impacting your system heating. Examine the pump to see if it needs to be repaired or replaced.

A Faulty Heating Element:

So, you have fixed the flow issue, but the water still will not warm up? The heater, on the other hand, could be the source of the problem. The heating element is likely faulty. If you are good at electric systems, just remove the item and see if it looks sort of burnt. If that is the case, it is time to get a new one.

Problems with the Control Panel:

Everything else in your spa, such as the heater & pump, is controlled via the control panel. Your heating system could be harmed if there is a problem with it. A spa expert is a perfect person to tell you whether it requires to be repaired or replaced. Fixing a hot tub’s control board is simple, but it will cost you a lot. If your gear is imported, the situation is exacerbated because parts are twice as expensive.

  1. The Jets Are Not Running:

Your hot tub’s jets can provide a relaxing water massage. It can ruin your overall hot tub experience if they are not functioning right. Fortunately, there are a few steps you may take to troubleshoot the issue and, perhaps, come up with a solution.

  • Make sure the jets are open by turning them.
  • Look for debris, like calcium deposits or dust.
  • Fill the tank with water, wash the filter, check for blockages in the plumbing line, & test the water.

If these measures fail, there may be an airlock within jet lines. To get rid of the air, turn on and off your jets. You can also unscrew the pump’s top fitting till you heard air escape. When you see the water begin to refill the pump once more, quickly replace the top fitting on the pump.

  1. Loud Pump:

Whether your hot tub water is murky, frothy, foggy, or smelling odd? If that is the case, we recommend purchasing a test strip & testing the water for chlorine, pH, & alkalinity. Then jolt the water by ensuring that chemicals & water care products are distributed efficiently and regularly.
