Salt Chlorinator Spare Parts

Typical service life is between 3 and 7 years, or equivalently between 5,000 and 12,000 operating hours. The most influential factors are: (1) water quality (hard water with a lot of lime degrades faster), (2) salinity (working outside the recommended range accelerates wear), (3) the presence of automatic polarity inversion (models with inversion reach the high end of the range; models without inversion, the low end), (4) manual maintenance (cleaning with dilute hydrochloric acid when applicable). Clear symptom of end of life: the control unit indicates correct production but the free chlorine in the water does not rise.

No. This is one of the critical points in salt chlorination: the cell is NOT compatible between brands, and within the same brand it is normally only compatible between exact sister models. The reason is that the electronic control unit works with very specific electrical parameters (voltage, current, number of plates, polarity inversion system) calibrated for a specific cell reference. A cell of a different brand causes, in the best case, continuous alarms or very degraded production; in the worst case, damage to the electronics of the control unit. Always replace the cell with the official reference of your chlorinator model.

Three critical data:

1. Brand name: printed on the front of the control unit. 2. Exact model (with production number): on the side or rear label of the control unit. Examples: "Astralpool Sel 100", "BSV EVo Basic 25", "Innowater SMC 30", "Zodiac GenSalt OE 17", "Hayward Salt & Swim 3C". 3. Production in g/h of the cell: typically 7, 15, 22, 30, 40, 60, 100, 160 or 200 g/h.

These three data together uniquely identify the replacement part. If the label is illegible, send a photo of the complete control unit to the technical team.

In order of rotation:

1. Dosing pump peristaltic tube (in models with integrated pH control): every 1-2 seasons. 2. PH and ORP/Redox probes (in models with automatic control): every 2-4 seasons. 3. Electrolysis cell: every 3-7 years (the most expensive part). 4. Cell vessel gaskets and plugs: every 4-6 seasons if leaks occur. 5. Fuses: only in case of occasional failure. 6. Power supply / motherboard: very long life, only replaced in case of failure (lightning, voltage peaks, water in the electronics).

The correct cleaning of the cell (necessary only in chlorinators without automatic polarity inversion, or in those that have it if the water is very hard) is:

1. Disconnect the chlorinator of the current and stop the pump of the purifier. 2. Close the stopcocks before and after the cell cup. 3. Loosen the thread of the cell cup and carefully remove the cell. 4. Visually inspect the plates: if they have white scale (limescale), clean them. 5. Prepare a 10% solution of hydrochloric acid (salfuman) in a plastic container (NEVER metal). Dilute with water, always adding the acid to the water, not the other way around. 6. Immerse the cell in the solution for 5-10 minutes until bubbles cease. Never leave more than 15 minutes. 7. Rinse thoroughly with fresh water and allow to drain. 8. NEVER scrub the plates with a brush, scouring pad or abrasive materials. The titanium coating is what electrolyzes; if scratched, the cell dies. 9. Reassemble, replacing gaskets if deformed.

If the water is very hard and the cell becomes fouled every 2-3 months, consider installing a descaler beforehand or changing to a model with automatic polarity reversal.

Most frequent causes, in order:

1. Probe out of calibration: most common. Recalibrate with pH 7.0 and pH 4.0 buffer solutions (you can sell them Quimipool together with the refills). After calibration, the probe should stabilize within 2-3 minutes. 2. Probe with scale or dirt encrusted on the membrane: immerse the probe tip in a 10% dilute hydrochloric acid solution for a few minutes to remove the scale. NEVER rub the membrane with a cloth, as this will damage the sensor. 3. Dry probe: if the probe has been out of water for a long time (typically after an incorrect wintering), the membrane dies irreversibly. It must be replaced. 4. End-of-life probe: probes last 2-4 seasons. If after cleaning and calibration it still gives erratic readings, replace it.

Recommendation: always have calibration buffer solutions at home (shelf life of about 2 years closed) to be able to recalibrate instantly.

Yes, they are accessible parts for home users:

• Cell: 15-30 minutes. Close stopcocks, loosen vessel threads, remove cell, install new cell with new gasket, retighten. CRITICAL: disconnect the chlorinator from the power supply before handling.
• PH/ORP probe: 10-15 minutes. Disconnect cable, unscrew probe from probe holder, install new probe, connect cable, calibrate with buffer solutions before starting up.
• Peristaltic tube: 5-10 minutes. Open the cover of the peristaltic pump head, loosen the connections of the old tubing, insert the new tubing following the direction of rotation of the rotor, close the cover. Prime the pump with product before normal operation.
• Fuses: trivial if accessible from the outside. CRITICAL: chlorinator disconnected from the mains.
• Power supply and backplane: requires disassembly of the control unit and handling of wiring. Service technician or experienced electrician recommended.

It depends on the brand and model. The most widespread ranges (Astralpool Sel, BSV EVo, Innowater SMC, Zodiac GenSalt, Hayward Salt & Swim) maintain an active spare parts catalog with availability of the original cell or an updated equivalent. On very old models or less common brands, the manufacturer may have discontinued the original cell but offer a current equivalent cell with matched connection. To confirm, indicate brand, model and production to the technical team: the availability of the original part or compatible equivalent is verified.

Rule of thumb: if the sum of parts to be replaced + possible service exceeds 60% of the price of an equivalent new chlorinator, it usually pays more to buy new equipment (which comes with factory cell and electronics, warranty and, usually, more efficient technology).

Cases where it is always worth repairing:

• Replacement of the cell alone (it is the most expensive part, but less expensive than the complete chlorinator).
• Change of probes and peristaltic tube (low cost operations).
• Change of fuses, gaskets, plugs (operations of few tens of €).

Limit case:

• Change of cell + power supply + some probes in a 10+ years old equipment: the cost is close to that of a new equipment.

Case where it rarely pays off:

• Motherboard failure + need to change cell: the cost of new electronics + new cell is usually above 70% of the new chlorinator, and the rest of the equipment is already worn. Here it almost always compensates to change the complete chlorinator.

Compatibility depends specifically on the make and model of your salt chlorinator. It is crucial to verify this with the manufacturer or an authorized dealer. Many manufacturers have compatibility guides on their websites or catalogs.

You should change the cell when you observe:

• A significant decrease in chlorine production
• Frequent low salinity alarms (even with correct salt levels)
• Excessive calcium deposits that are not removed by cleaning
• The cell has exceeded its expected life span (usually 3-7 years)

The typical lifetime of a salt chlorinator cell is 3 to 7 years. However, this may vary depending on factors such as:

• Water quality
• Frequency of use
• Regular maintenance
• The quality of the cell

You can check the operation of your salt chlorinator in several ways:

• Check the controller display to see if it shows errors
• Use a chlorine test kit to check the levels in the water
• Visually inspect the cell for wear or deposits
• Observe for bubbles coming out of the cell when it is running

Regular maintenance includes:

• Checking and adjusting salt levels regularly
• Maintaining the pH and alkalinity of the water at optimum levels
• Protecting the equipment during the winter in cold climates
