ES3 Replacement Electrode Kit (post 2014)

Enviroswim ES3 Replacement Electrode Kit – Post 2014 / Grey Face (CUROD-ES3POS-TR)

Replace the copper and silver electrode rods in your Enviroswim ES3 sanitiser system with this genuine Enviroswim electrode kit. Suits ES3 units purchased after November 2014 but before 2017 (grey face panel, metal plug). The copper and silver rods ionise the pool water, providing algaecidal (copper) and antibacterial (silver) action. Supplied in pairs, complete with lead and metal plug for easy installation.

Typical lifespan: 18 months to 4 years depending on bather load and pool volume. Rotate electrodes every 3–6 months for even wear.

Is This the Right Part for My System?

The ES3 system has been produced in three generations, each with different replacement parts. Use the control box face panel colour and the cable connection type to identify your system:

• Grey face panel, Metal plug (Post 2014 & Post 2017): This listing – CUROD-ES3POS-TR
• V3 – White face panel, Plastic plug (Post 2017): ES3 Electrode Kit – V3 Post 2017 (CUROD-V3-TR)
• Blue face panel, No lead / bare wire (Pre 2014): ES3 Electrode Kit – Pre 2014 (CUROD-ES3PRE-TR)

If you are unsure, check both the face panel colour and the plug type on your existing electrode cable before ordering.

Frequently Asked Questions

How do I identify which ES3 system I have?

Check two things: the colour of the control box face panel, and the cable connection type on your existing electrodes. The Post 2014 system has a grey face panel and a metal plug connection. The V3 (Post 2017) has a white face panel and a plastic plug. The Pre 2014 system has a blue face panel and a bare wire (no lead) connection. Ordering the wrong kit will result in an incorrect fit.

How long do the electrodes last?

Typical lifespan is 18 months to 4 years. At 0.4 copper in a 50kL pool, expect around 18 months. At 0.2 copper in a 50kL pool, expect around 36 months. Rotating the rods every 3–6 months extends their life by ensuring even wear.

How do I know when the electrodes need replacing?

Signs of depleted electrodes include reduced water clarity, persistent algae growth despite correct chemical levels, or the ES3 displaying a low-output warning. Visually inspect the rods — when they are significantly reduced in diameter, it is time to replace them.

Should I replace the oxidiser plates at the same time?

If both the electrode kit and oxidiser plates are nearing end of life, replacing them together saves labour and ensures the full system is restored. See the related parts links above for the correct oxidiser plates for your system.
