Most Common Hot Tub Repairs and How to Avoid Them

Find out more about the most common hot tub repairs and how to avoid them. The Hot Tub Engineer provide hot tub repairs throughout Maidstone and Kent. We look at common hot tub problems from not heating up properly to hot tub jets not working.

Common Hot Tub Problems

Hot tub heater issues are frequent but easy to resolve on your own. There are often two potential causes: a problem with the heating element or a problem with the water flow.

The heater might stop working for a number of reasons, but one of the most frequent is when the pH of the water is too low and the heater starts to corrode. Unfortunately, you have to replace your heater after it has rusted. Start by removing the filter from the housing.

Examine the filter. Is the filter blocked or dirty? Make sure to remove the majority of the dirt from the blades when you clean the filter with a hosepipe. If the water is clear, try running the tub for five minutes without the filter in. Make sure no huge bits of trash can travel down the filter housing while the filter is removed. This should fix the hot tub and leave it nice and warm again.

Hot Tub Is Leaking

If you suspect your hot tub is leaking, turn it off immediately. As the most common leaks typically begin in the pump, you may want a new pump or a repair for a portion of the pump, such as the seal.

If the drop is coming from the heater, you'll need to replace it. Begin by inspecting all of the connections, including the pipes and jets, and then look for any holes or fractures in the tub's shell. A hole in the air control valve might be the source of the problem. Inspect all of your valves; some are fastened together with a gasket between them, which might fail and cause leaking.

One of the most frequent areas for a hot tub leak to occur is the circulation pump. Before inspecting this region, turn off the electricity and make sure there are no leaks beneath the pump. If there was no leak from the pump, the heater may be the issue.

Each internal component of the heater, such as the pressure switch and other components, has the potential to be an issue. You could replace that component, but it's more probable that you'll need to buy a new heater or get it fixed. Hot tubs have a variety of valve designs, and each one may be fixed in a different method. To avoid draining, some tubs have valves installed on one side of the pump.

Other valves have compartments that are fastened together with a gasket between them; this gasket has a history of causing leaks. Make careful to check and repair any worn-out valves on your hot tub.

Make careful to inspect all connections, jets, and pipes. While some connections simply need tightening or sealing, others need a complete replacement. Make sure you get the correct components if your gasket fails.

This is because there are different gaskets for different types of spas. You would assume that a leak could never occur because the majority of hot tub shells are built with layers. However, a jet or other component linked to the shell might create a leak rather than the shell itself.

Hot Tub Pump Problems

If your tub's pumps have begun to make loud noises, this is typically an indication that they need to be replaced. Squealing noises indicate that the bearings have worn out.

Grumbling noises suggest that you should make some adjustments, and a loud hum indicates that you should inspect the pumps for loose screws. Check that the valves are open and that no debris is obstructing them; issues with the pumps might harm your jets and the filter. You should also ensure that your filter is not clogged and that no water has entered it.

Hot Tub Is Tripping The Breaker

A Ground Fault Circuit Interrupter (GFCI), is a circuit breaker that guards you against electrical failures. A GFCI is installed in your hot tub and will activate. The power will be turned off if the electrical channel becomes dangerous. The GFCI is sensitive to ensure your safety, and even the tiniest problems can trip the breaker.

Error Codes On Hot Tub’s Control Panel

When there is a problem, the control panel for your hot tub shows error messages. The most frequent messages that may be shown are listed below, albeit they vary based on the make and type of your tub:

FLO stands for a pressure or water flow error.

OH indicates that the sensors have found hot water, which might lead to overheating.

DRY indicates that there is not enough water flowing through the heater.

COOL indicates that the water is cooler than what is advised.

The sensors inserted into sockets A or B are not functioning if they display SNA or SNB.

Hot Tub Jets Not Working

It's important to ensure that the filter is clean as the remedy above when the hot tub jets are not operating. An airlock is the second most typical reason why the jets in your hot tub aren't operating.

You can loosen the pump unions until a trickle of water leaks out, at which point you can re-tighten them to release the airlock. Second, you might be able to purge the airlock by turning the pumps on and off. Last but not least, you can loosen the water diverters on some tubs.

Hot Tub Too Hot?

Pump operation generates heat as a result of water friction. Heat is produced by pumps and pipelines with moving water in them. In light of this, checking all hot tub settings is a fantastic location to start the repair. Every day, the hot tub cleaning cycle can be set; as a result, pumps overheat and the heat is transferred to the water.

Pre-heat settings are another thing to take into account with older models. No matter what temperature you choose to choose, this option will heat the tub between specific intervals.

NOISY PUMP - Most Common Hot Tub Repairs and How to Avoid Them

Noisy Pump

You must discover a quick fix for a noisy pump unless you want to soak in your hot tub wearing earplugs. Follow the instructions below to locate a fix if your pump is generating a loud shrieking or deep growling noise. a deep growl? Your pump needs water.

Remove any obstructions, top off the water and check that the valves are open. Squealing at a high pitch? Your sense of direction is poor. Make sure you replace the circulation pump and grease the bearings.

Dirty Water

Is the water in your hot tub frothy, opaque, murky, or emitting an odd odour? If so, it is advised that you purchase a test strip and measure the pH, chlorine, and alkalinity of the water. The next step is to shock the water and make sure that the chemicals and water-care supplies are being dispersed.

Try cleaning the empty tank, spritzing water in it, and repairing any broken parts if that doesn't work. It will also be treated with hot tub supplies and refilled with new water.

You should also clean the hot tub cover at this time. You should remove the cover and set it down against a fence or the side of your house. After that, rinse it with water and clean the hot tub with different cleaning agents. It should be given one more wash before being properly dried and placed back in the tub.
