It’s a lovely evening. You’re ready to sit back, relax and enjoy your bubbling, steamy hot tub. You have a towel, a salty snack and a cold drink, ready to go. But on removing the hot tub, you find the water ice cold, tub’s breaker trips when turned on, jet not working properly or your pump produces ear-splitting screech.
Your evening is not working out as planned regardless of your hot tub water problems. You need quick hot tub repairs. This article explores five common hot tub problems and how to fix them yourself.
1. Your Hot Tub Won’t Heat Up Properly
If your hot tub is having problems getting warm, it could be the heater element or low flow from your pump. Most heating failure result from corrosion caused by low PH in water supply. Any PH below 7.0 damages the heating element and trips the GFCI breaker. Most problems are manageable with proper water chemistry maintenance.
To troubleshoot the heater, check the thermostat and filter for damage. A multimeter can help you identify the culprit in the electrical components.
2. Jets Are Not Working Properly
Hot tub jets are the hardest working piece of equipment. Jets receive water outflow from the pump. When jets start failing, you will need to diagnose hot tub problems relating to the pump.
Check your pump’s priming to make sure it is working properly. Open the access panel and the airlock valve close to the pump. This releases air from the line and purge system, allowing more water to stream through the jets.
Clogged filters or water intakes can also cause jet issues. Clean them to enhance water flow. If you cannot clean the filter properly, you may need to replace.
3. Your Hot Tub Control Panel Is Displaying Errors
Although they show something is wrong, sometimes error codes can be confusing and don’t necessarily pinpoint the cause of problem. Manuals have many error codes. The five common error codes include:
- FLOW: Appears when there is improper flow. You may also see it when your jets misbehave. Check for blockages, clean or replace your filter and determine if the circulation pump is working.
- OH: Appears when the water is too hot to use. Check your circulation system and filter. Also ensure your pump is not running for very long periods. You may need to replace the temperature sensor. But if the display appears and your water is not hot, it is advisable to call hot tub experts.
- DRY: Means insufficient water is getting to the heating element. You may have to top your hot tub. Please use a hose filter to prevent impurities from getting into your spa and plumbing system. Double check to make sure no debris is present in your circulation system before restarting.
- COOL: Appears when the actual water temperature is 20 degrees lower than what you set it at. Place your hot tub cover back and allow the heater to run for 24 hours.
- SNA / SNB: Sensors A and or B might be going bad or sensor circuit has problems. You may need to get a new sensor. Call an expert if you’re uncomfortable or unsure.
4. Pump Is Making Loud Noises
When you hear a grumbling, high-pitched squeal or growling noise from your pump, it is an indication of a problem. Remove clogs, top off your water and ensure all valves are open. Squealing sounds indicated bearings are worn out. You can try lubricating them, but eventually, you’ll have to replace the pump.
5. GFCI Breaker Keeps Tripping
Frequent GFCI tripping means you could spend a significant amount of time troubleshooting your hot tub. A malfunctioned hot tub GFCI breaker trip is easy to fix. However, you need to work with electricity to troubleshoot and repair. If you are uncomfortable, please call a professional. (hint hint, we’re professionals!!)
