5 Common Hot Tub Problems and Solutions August 7, 2020 09:00
Hot tubs are a great way to relax and unwind after a hard day at work. The last thing you need is to come across any hot tub problems.
However, we have your back! Take a look at our list of common issues to help with your hot tub troubleshooting.
We’ve made it easy to detect a hot tub problem and discover the right solution – so you can get back to some well-deserved R&R.
1. Hot tub not heating up properly
Are you struggling to get your hot tub to the right temperature? Hot tub heater problems are common but they are usually straight forward to fix yourself.
There are two main reasons your hot tub isn’t heating up properly; faults with the heater element, or problems with the water flow.
The heater can fail for a few reasons but one of the most common is if it has been subject to corrosion caused by low PH in the water supply. Unfortunately, once your heater is corroded, it needs to be replaced.
If you have an FLO error or circulation fault then follow our guide to resolve this. It most likely is time to clean your filters. For more information on how to clean or replace your filters, read our article here.
Check your water levels too as the hot tub heater relies on a sufficient flow of water. If there isn’t enough water and the flow struggles to circulate, it will fail to operate.
2. The hot tub is leaking from somewhere
If you suspect your hot tub is leaking, the first thing you should do is turn off the power supply. Once you have done this, it’s time to find the source of the leak.
The most common hot tub leaks are usually from the pump. If you find it is coming from the hot tub pump, you may need a new pump or replacement part within the pump such as the seal. Outdoor Living does not recommend repairing pumps as this is always a short term fix and it will only be a temporary repair.
If your leak is coming from the heater, you will more than likely need to purchase a replacement.
Check your hot tub connections including all pipes and jets. Make sure to complete visual checks around the shell of the tub to look for any holes or cracks.
A hot tub air control valve leak could also be a culprit. Inspect all your valves as some have compartments bolted together with a gasket between them, this is sometimes known to fail and cause leakage.
If your hot tub is still under warranty and was purchased from Outdoor Living, we will be able to fix your leak. Please be aware that if you do try and fix the leak yourself, it could invalidate your warranty.
3. There are problems with the hot tub pump
If your hot tub pumps have started to make loud noises, it’s usually a sign they need to be replaced.
Squealing sounds indicate the bearings have worn out and grumbling noises may mean you need to make a few adjustments. If you get a noisy hum coming from the pump, check for loose bolts and screws.
Check the valves in your pump are fully open and remove anything that could be causing it to clog up.
Hot tub pump problems can impact the functioning of your jets. Again, check to see if your filter has got clogged up and make sure it hasn’t taken in any water.
It’s really important to keep your filters clean, especially for a fully functioning, safe hot tub. For more information on how to clean your filter, check out our guide here.
4. Turning on the hot tub is tripping the breaker
Your hot tub includes a ground fault circuit interrupter (GFCI), which is fitted to protect against any electrical faults that could cause an electrical shock to a person.
If the electrical path the current is flowing through becomes unsafe, your GFCI will kick into place and your hot tub power will shut off.
For safety reasons, the GFCI is very sensitive and even just the smallest of issues can cause the breaker to trip.
A number of components may trip your breaker, although these could be a simple fix, we advise that because you’re dealing with electricity and water, to please give us a call and we can offer the best advice on the next steps.
5. Hot tub control panel displaying error codes
Your hot tub control panel will display error messages when it has found an issue with your settings.
Hot tub error codes will differ depending on the model and make of your tub, but below we have listed a few common messages that may be displayed.
FLO = there is a water flow or pressure error
OH = the sensors have detected a high-water temperature which could cause overheating
DRY = the heater is experiencing an inadequate flow
COOL = the water temperature is below the recommendation
SNA or SNB = your hot tub has shut down as the sensor plugged in to socket A or B is not working
If your hot tub control panel is alerting you to any other error codes, please refer to your user manual for a full list of codes and their meanings.
To avoid these issues from occurring in the first place, we recommend keeping on top of your maintenance by having regular hot tub servicing. For more information on our hot tub servicing from our team of trusted hot tub specialists, visit here.
