What Does EC Mean on a Hot Tub? A Simple Explanation

For hot tubs, there are a variety of codes and acronyms that can be confusing to decipher. One of the most common codes is EC. So, what does EC mean on a hot tub? Answer: EC stands for economy mode.

When you turn on EC mode in your hot tub, it runs at a lower temperature to save energy. It’s a good option if you’re not planning on using your hot tub for a while or if you want to save on your energy bill.

However, when the water temperature drops below the preset thermostat, the heater will turn on automatically to maintain the desired temperature.

What is EC in a Hot Tub?

A hot tub is a great way to relax and unwind after a long day. If you see an EC message on your hot tub control panel, it can be confusing and frustrating. Here, I’ll explore what EC means on a hot tub and how to understand and troubleshoot EC messages.

What is EC Message?

You already know that EC stands for Economy Mode, which allows your hot tub to conserve energy by running at a lower temperature. When you turn it on in this mode, it’ll switch to “filter mode,” which means it’ll only circulate the water without heating it.

On the other hand, when the water temperature is below the preset thermostat, it’ll turn on the heater automatically.

ECN or EC: What Do They Mean?

If you see an ECN message on your hot tub control panel display, it means that your hot tub is currently in economy mode and is heating up. On the other hand, if you see an EC message, it means that your hot tub is in economy mode, but the water temperature has dropped below the preset thermostat.

In this case, you should adjust the temperature setting or check for any other issues that may be preventing the heater from turning on.

How to Access the Control Panel?

Depending on the model of your hot tub, the control panel may be located on the top of the hot tub, on the side, or on a separate remote. After finding the control panel, you can use the buttons or touchscreen to navigate through the various settings and options, including the economy mode setting.

You can watch how to use a hot tub control panel from the Master Spas video:

Using EC Mode

EC mode, also known as economy mode, is a setting that you’ll find on most hot tubs. It’s designed to save energy and reduce costs by running the hot tub at a lower temperature.

This section will cover how to operate a hot tub in EC mode and the different heating modes that are available.

Operating in Economy Mode

When you turn on operating economy mode, your tub will run at a lower temperature than in standard mode. It’s a great option if you’re not planning on using the hot tub for a while. To switch to economy mode, simply select the option on your control panel.

Heating Modes

Only Heat Mode will heat the water to the desired temperature and maintain it. The standard mode does the same, but it’ll also turn on the jets periodically to keep the water circulating.

Programmed Filter Cycle

You’ll find another feature of EC mode is the programmed filter cycle. This is a pre-set time period, during this time hot tub will automatically filter the water. It helps to keep the water clean and clear. Also, it helps reduce the amount of chemicals needed to maintain the water.

Sleep Mode

Sleep mode is a feature that you’ll find in some hot tubs (not all brands or models). When the sleep mode is ON, it’ll turn off all of its functions except for the heater.

This means that the water will continue to be heated, but the jets and other functions will be turned off. It’s a great feature if you want to save on your energy bill.

Smart Winter Mode

Using smart winter mode, your tub automatically adjusts the temperature of the water based on the outside temperature. So that your tub will use less energy during the winter months when the outside temperature is colder.

Troubleshooting EC Errors

When a hot tub displays an EC error code, it means there is a problem with the unit’s operations. Fortunately, you can take some steps to troubleshoot the issue and get the hot tub back up and running.

This section will cover the most common error codes and what to do when they appear.

Error Codes

ECThe water in the tub is too conductive.
SLThe temperature sensors are not working properly.
OHThe water temperature is too high.
