Arctic Spa Error Codes for 2020 and new Arctic Spa Custom Series

Posted by Christian Staples on 9th Dec 2021

Check out our new video on the Error Codes for 2020 and new Arctic Spa Custom Series hot tubs and what to do to fix them!

I’m Christian Staples with Arctic Spas. One huge advantage Arctic Spa owners have over other brand owners is the free over-the-air software updates. Just like your computer or phone, the software gets better and better as time goes on giving you more features.

With the latest software update 1.0.64, the error codes were changed from abbreviations to numbers. They will now read ER and then a number such as 01, or 02, and so forth. If you do see any of these error codes come up, the first thing you will want to do is to turn the power off to the spa and then back on again. This will reset the spa. If it is a real error code, the code will return shortly. If it was just a false error, it will be erased and everything will return to normal. Some of these error codes will not allow the heater to turn on to protect the spa. If you have cooler water that where you have it set, double check to see if you have an error code on the topside.

Here is a list of the errors and what they mean and how to fix the error.

ER 02 – Heater Over Temperature – This means the heater is too hot and reached 119 degrees. This is usually fixed by just resetting the spa by turning the breaker off and back on again. If it comes back, then you will need to have a tech check it out.

ER 03 – Spa Over Temperature – This means the spa is hotter than where it is set for. You can leave the top off to allow it to cool down or add some cold water to the spa.

ER 04 – Spa Temperature Probe – The temperature probe that reads the spa water temperature is either disconnected or needs to be replaced. You can try unplugging the temperature probe and plugging it back in.

ER 05 – High Limit - Heater is too hot and reached 118 degrees. This is usually fixed by just resetting the spa by turning the breaker off and back on again.

ER 07 – Freeze Protect – The spa water temperature is too cold and the spa will run other pumps to circulate the water to prevent it from freezing. Usually, you just have to wait for it to heat back up.

ER 08 – pH High – The pH of the water is too high. You will need to add ½ cap of the Adjust Down for regular hot tubs and 1-1/2 caps of Adjust Down for All Weather Pools.

ER 09 – Heater Probe Disconnected – The probe measuring the temperature at the heater is either disconnected or needs to be replaced. You can try disconnecting the probe from the motherboard and plugging it back in again to see if this solves the problem. If it doesn’t, the probe will probably need to be replaced.

ER 10 – Heater Probe Test Failed – When the spa is started up, the heater is tested to make sure it is working properly. Turn the breaker off to the spa and back on again to reset it. If it comes back, you probably need a tech to check it out.

ER 11 – SpaBoy Communication Error – If your spa is equipped with SpaBoy Saltwater System, it is not communicating with the motherboard. You can try unplugging the SpaBoy and plugging it back in at the motherboard. If this does not solve the problem, you will need a tech to check this out.

ER 12 – Heater Spa Temperature Calibration – This measures the water temperature at the spa and the heater. It there is a difference between the two temperatures when the pump #1 is running and the heater is off, the error will be displayed. Turn the breaker off and back on again to reset it. If it comes back, a tech will need to take care of it.

ER 13 Heater Temperature Way above the Spa Temperature – If the temperature of the heater is way hotter than the spa temperature. It will shut off the heater, wait and then try it again. Usually this is caused by a restriction on the flow through the heater. This can be caused by too many jets closed, a restriction in the plumbing. If you cannot figure out this restriction, we need to get a tech to find the problem.

ER 14 – SpaBoy Probe – This probe is not reading a change when the SpaBoy has been on for a period of time. This could be caused by low salt levels, which you would want to check with the test strips and adjust. It could also be a hardware issue with the SpaBoy Probe or the SpaBoy Generator. You would need a tech to diagnose these issues if it is not from low salt.

ER 15 – pH Low – This is unusual so double check with regular test strips and if it is still showing low, you will have to use Adjust Up to bring the levels
