Top 4 Common Spa Issues & Solutions

1. Faulty Jets

Jets are one of the most desirable and relaxing features of a spa. In fact, most people associate the feeling of being in a spa with the use of jets. Not to mention, the jets are usually the most exciting aspect of spa use for kids. If your jets do not appear to be functioning properly, you could be experiencing one of the below issues. Note: We do not recommend the use of a plunger to attempt DIY repairs on your spa as it can damage your spa and void your warranty.

Debris & Clogs

The most common problem is debris obstructing or blocking the airflow through your jets. The calcium build up is typically the culprit in this instance, but it is always best to ensure your jets are wide open and clear any debris. Then, refill your spa water, clean the filter, and as an added measure, we recommend checking all spa plumbing for any clogs.

Potential Air Lock

A recently refilled spa can sometimes result in an airlock. The first step you can take to try and clear out the trapped air is to turn your spa jets on and off a few times. If this does not do the trick, you may need to loosen the top fitting on your pump until you hear air or see water escape. Once done, tighten the fitting again.

2. Noisy Spa Pump

A noisy pump can not only result in damage to your spa, but it can ruin the relaxing experience you want from your spa. If you suspect an odd noise coming from your spa pump, there are two sounds you should be listening for: a growling/grumbling noise or a high-pitched squeal. If you hear either of those, you probably have a problem with your spa pump.

Growling

Growling or grumbling is often related to a lack of water flowing through your pump. Clogs in your circulation system are usually the cause. The quick fix for this issue is to ensure all valves near your pump are open and your spa water is topped off to allow sufficient water flow. 

Squealing

This sound is typically the result of bad bearings on your spa pump. While this sound is generally more off-putting than the growling mentioned above, you can continue to use your spa safely. Albeit, the noise will only worsen over time. The first thing to do is lubricate the bearings, this will alleviate the sound for the time being, but you'll likely need to replace the circulation pump down the track. 

3. Cold Spa Water

Unless it is the middle of the day, 40 degrees and your spa is outside, no one wants to jump into a cold spa. Furthermore, the phrase 'cold spa' doesn't even sound right. In the event of cold spa water, you should always check your water level first. Second, check your circulation system for clogs, ensuring you also wash or change your filter. 

If that does not fix the issue, try switching your heater breaker off and on, or press the heater's reset button. There's a chance your heat may have switched off due to getting too hot or if the air is trapped in your lines, resetting the heater should start it up again.

Another cause for cold spa water is an airlock, which can occur after refilling your spa. We discuss airlocks in more detail below.

If you have reached this stage with no heat there's a high chance you have a bad heating element. This is usually a more technical task and one for your local technician. If you are confident with your troubleshooting abilities, you are able to remove the heating element yourself to see if it has burned out. If so, call a technician or ask for support from the manufacturer.

4. Weak or Low Water Flow

Weak or low water flow is another common issue with residential spas, and is generally related to one of the following:

Airlock

As we mentioned above, airlocks can be a common occurrence after refilling your spa. An airlock means air has found its way into your plumbing lines and is preventing water from flowing normally. To fix an airlock, you will need to drain the air out of the system. First, turn off your entire spa system. Then, look for small bleed screws at the end of the pump, open them and let the air out. You may find that your system has screws on top of the pump as well. Once you have done this, reapply the screws firmly and turn your spa on to see if the water flow has returned to normal. 

Faulty Pump

Your spa pump is responsible for circulating water around your spa, including through the spas plumbing. If your pump isn't running, use a multimeter to test whether the pump is receiving power. If it is, but the pump is still not running, it likely needs replacing or repairing by a professional. This is a more serious issue and should be dealt with swiftly to avoid electrical problems down the track. Note: Water and electricity are deadly when mixed, so we always recommend contacting experts if working with electricity.

Filter Problems

If your filter is overdue for a wash or completely worn out, this will directly affect water flow. Check your filter for anything out of the ordinary and clean if necessary. If you notice signs of wear and tear, which will occur over time, you may need to replace them.

Low Water Level

The low water level is another common cause of reduced water flow. There needs to be sufficient water in order for there to be sufficient water flow, it's simple math. Luckily, this is an easy fix. Simply top off your spa and run a test to see if that resolved the issue.
