Zodiac, and EiSalt Chlorinator Replacement Parts

The production rate (12, 21, or 30 g/h) is indicated on the unit’s label, usually on the control panel or near the cell. You can also find it on the purchase invoice or in the unit’s manual.

It’s essential to confirm this before purchasing the electrode: the DT-12 (€649.00), the DT-21 (€669.00), and the DT-30 (€829.00) are not interchangeable. If you can’t find this information, call us at 91 128 55 90 with a photo of the unit, and we’ll confirm it for you.

Start with the EPDM gasket (€41.90): It’s the most common cause of leaks and a maintenance part that should be replaced every time you open the unit, even if it shows no visible damage. Also check the vessel’s locking thread (€31.94): if it doesn’t seal properly, it can cause the same leak even if the gasket is in good condition.

Only if the leak persists after replacing both parts should you check whether the electrode holder (€139.00) is cracked. Contact our technical support if you have any questions.

Before checking the electrode, check the salt level: the system needs a minimum of 4.0–5 g/l to function properly, and a low level triggers the “low salt” alarm and automatically reduces production to protect the electrode. This is the most common cause of “low output” and does not require any parts from this parts list.

If the salt level is correct and the problem persists, the electrode may have reached the end of its service life, which is estimated at between 8,000 and 10,000 hours of operation depending on the model. Call us at 91 128 55 90 to assess your situation before making a purchase.

The Tecno DT-12, DT-21, and DT-30 electrodes are manufactured by Idegis, the same company that manufactures the EiSalt for Zodiac, so in some cases they may be compatible with other chlorinators from the Idegis brand that use the same cell. Even so, don’t assume they’re compatible: there may be slight differences in connectors or threads between product lines.

Before purchasing, confirm the exact part number of your current electrode or contact us via the contact form with a photo of the label. Call 91 128 55 90 if you have any questions.

This is a typical sign of a worn-out electrode mounting kit (€14.90). Do not force the electrode by trying to secure it by hand: replace the mounting kit to ensure a stable electrical connection and prevent damage to the terminals.

While the cell is open, take this opportunity to also check the contact protector (€9.90). If you have any questions about installation, contact our technical support team.

We recommend inspecting the terminal cover (€9.90) at least once per season, especially if the equipment is installed in a humid area—which is common, since the EiSalt is designed specifically for such environments thanks to its IP24 rating. A broken or missing cover leaves the terminals exposed to corrosion.

It’s a quick check, and the part is inexpensive, so it’s a good idea to include it in your regular maintenance routine along with the EPDM gasket. If you have any questions, call 91 128 55 90.

These are separate parts with complementary functions. The electrode holder (€139.00) is the complete housing that holds the electrode inside the cell; if it is cracked or damaged, the entire assembly will no longer be watertight. The anchoring kit (€14.90) is the small part that secures the electrode in place inside the holder.

If the housing is in good condition but the electrode moves or loses contact, the anchoring kit—which is much more affordable—is usually sufficient. Call us at 91 128 55 90 if you have questions about which one you need.
