Hydropool Swim Spa Error Codes – Guide to Understanding Your Spa

Owning a Hydropool Swim Spa means enjoying luxury and relaxation. However, sometimes things go wrong, and your control panel throws confusing codes in a desperate attempt to communicate. These codes are designed to help you understand what’s happening with your spa and guide you toward a solution.

If you’re facing confusing codes, fret not! In this guide, we’ll walk you through the most common Hydropool Swim Spa error codes. We’ll explain what they mean and what you can do about them. Let’s get started.

7 Common Hydropool Swim Spa Error Codes

1. Hr – Internal Hardware Error

When you see “Hr” on your display, it means there’s an internal hardware problem. This is something the system has detected on its own.

What to do: Turn off the spa, wait for a few minutes, then turn it back on. If the error doesn’t go away, you’ll need to call in a professional to take a closer look to determine the underlying cause.

2. Prr – Temperature Probe Problem

“Prr” means the spa is having trouble reading the temperature accurately. It’s related to the regulation probe, which constantly monitors the water to ensure it’s within safe operating limits.

When this error occurs, it could mean the probe is malfunctioning or reading temperatures incorrectly.

What to do: Check the temperature probe for any obvious issues, such as loose connections or visible damage. You can try resetting the system to see if that resolves the error, but if it continues, the probe may need to be replaced by a technician to restore proper function.

3. HL – High Limit Error

This error shows up when the water temperature at the heater reaches 119℉ (48℃), which is above the safety threshold.

The spa’s system automatically triggers this error to prevent the water from becoming dangerously hot, protecting both the spa and its users.

What to do: Don’t use the spa when this error occurs, as the water may be too hot for safe use. Allow the water to cool down naturally, and check that the filtration system is running properly to maintain good water flow.

To help bring temperatures down, open your cover and leave it off for a while, allowing the cool outside air to pull some of the heat out of the water.

If the error doesn’t clear after cooling, it’s best to contact a professional to inspect the heater and filtration system.

4. FLO – Flow Error

“FLO” means there’s a problem with water flow in the system. This error occurs when the spa isn’t detecting any water movement while the filtration pump is running. It could be caused by a blockage or an issue with the pump itself.

What to do: Start by checking the filters and pump for any blockages or debris that may be preventing water from flowing. Clean the filters if necessary, and make sure the water levels are adequate.

If everything appears to be in good condition and the error still doesn’t clear, it’s time to call a repair service to inspect and fix the issue.

5. UPL – Configuration Error

“UPL” indicates that the spa’s system software hasn’t been properly configured, and is usually only seen on new spas. This can happen if the low-level configuration software isn’t downloaded correctly, which may affect the spa’s performance or functionality.

What to do: Try restarting the spa to see if the error clears.

If the problem persists, it’s likely that a technician will need to update or reprogram the software to ensure everything is functioning as it should. It’s a more technical issue, so professional assistance is usually required.

6. OH – Overheat Error

The “OH” error shows up when the water in the spa reaches 108℉ (42℃). This is a safety measure to prevent anyone from using the spa when the water becomes dangerously hot.

What to do: Turn off the heater immediately and allow the water to cool down to a safe temperature before using the spa again. Never attempt to use the spa when the water is this hot, as it can be hazardous.

If the error keeps reappearing, it’s best to call a professional to inspect the heater and ensure the temperature controls are functioning properly.

7. AOH – Ambient Overheat

While OH signals your water itself is too hot, “AOH” means the temperature inside the spa cabinet has risen too high.

This can happen if the area around the spa is not properly ventilated, causing the internal spa pack to overheat. If left unchecked, this could damage the system or affect performance.

What to do: Make sure there’s good airflow around the spa by checking the area for any obstructions that could be blocking ventilation. Remove any objects that may be causing the heat to build up, and allow the spa to cool down naturally before attempting to use it again.

If the error persists, you may need a technician to inspect for further issues.

Basic Troubleshooting Tips for Hydropool Swim Spas

  • Reset the System: Many error codes can be cleared by simply turning off the spa, waiting for a few minutes, and turning it back on.
  • Check for Obvious Issues: Make sure the water level is correct, the filters are clean, and there are no blockages in the pump.
  • When to Call a Professional: Some issues, like internal hardware problems or software errors, require a professional repair service. Don’t hesitate to call if you’re unsure or if the errors persist.

How to Avoid Error Codes

  • Regular Maintenance: Clean your filters regularly and keep your water balanced. This helps keep your spa running smoothly and reduces the chances of error codes popping up.
  • Seasonal Care: Protect your spa from extreme temperatures by following seasonal maintenance tips. Proper care during hot summers and cold winters can prevent overheating or flow errors.
