Supplied as a Complete Cell (rule CELL-1.0)

This part is the complete cell — the electrode and its housing supplied together as one assembly. There is no separate electrode-only part for this model, so a worn electrode means replacing the cell as a unit.

Before fitting, inspect the union o-rings in your pipework and replace any that are flattened, glazed or cracked. They are inexpensive and they are the usual cause of a leak after a cell change.

Specifications

• Part number: W202041 (Complete Cell LM2 20 Packed)
• Model: LM2-20
• Plates: 7 rectangular plates
• Type: Reverse-polarity, self-cleaning
• Supplied as: Complete cell — electrode and housing together
• Unions: 1½" union thread
• Brand: Zodiac Clearwater, a Fluidra brand

Chlorine output is set by the chlorinator's power supply, not by the electrode alone. The same cell can produce a different gram-per-hour figure in different models, which is why published output figures for these parts vary between sellers. Match on chlorinator model, not on a gram rating.

Warranty

This cell is covered by the Zodiac express warranty under the current Fluidra warranty schedule. The term depends on the chlorinator it is fitted to and on whether the installation is residential or commercial, so check the current figure on our warranty information page or ask us before you order. Cover is conditional — the conditions below are the ones that actually catch people out.

Warranty Conditions Worth Knowing

• It must be bought from a Fluidra Authorised Dealer. Zodiac's express warranty only applies to product purchased from an authorised dealer. We are one. A cell bought from an unauthorised online seller may not be covered at all.
• Cover starts 30 days after the date of purchase to allow for installation.
• Residential single-dwelling pools. Cells used at hotels, swim schools, rehabilitation centres, apartment or townhouse complexes and other multi-dwelling or commercial sites are covered for a shorter period.
• Water chemistry is a condition. Cover assumes water balanced to AS 3633, pH held between 7.2 and 7.8, and free chlorine not exceeding 4ppm. Damage from scaling or corrosion caused by out-of-balance water is excluded. Keep your test results.
• Register the product with myFluidra using the serial number and proof of purchase.

Why the Warranty Is Better Here

• We are an authorised Zodiac and Fluidra dealer and warranty agent, so buying from us satisfies the authorised-dealer condition on its own.
• Claims are assessed and handled by us in-house, not bounced to a supplier who bounces you to the manufacturer.
• Our team includes ex-Astralpool and ex-Hurlcon technicians who built and serviced this equipment.

Genuine Only — And Why That Matters

The replacement cell market is full of aftermarket, generic and copy electrodes, often listed so they look like the real thing. Non-genuine cells typically use a lighter titanium substrate and a lower-grade mixed-metal-oxide coating, which wears through early and drops chlorine output well before the promised life. Fitting a non-genuine part can also affect cover on the chlorinator itself. If a genuine cell is advertised well below the going rate, it is worth asking what is actually being sent.

When to Replace

Replace the electrode when the chlorinator reports low output or a low-salt fault that persists after the salt level is confirmed correct, when the plates show bare titanium or flaking coating, or when chlorine production has clearly fallen off with balanced water. Scale on the plates is not failure — a scaled cell often recovers after cleaning. Check for scale before condemning a cell, particularly in hard-water areas.

Frequently Asked Questions

Is this the complete cell or just the electrode?
Complete. The LM2 is supplied as a full cell assembly — electrode and housing together. There is no separate electrode-only part for the LM2.

Will an LM3-20 electrode fit my LM2-20?
No. The LM2 and LM3 are different generations and are not interchangeable. Zodiac sells dedicated LM2-to-LM3 conversion kits for exactly this reason. Ask us if you would like to convert rather than replace like-for-like.

How do I confirm I have an LM2-20?
The label on top of the cell reads MODEL LM2-20. If it is unreadable, send us a photo of the cell and the power pack and we will identify it.

Do I need to re-plumb to fit this?
No. The LM2 cell uses standard 1½" union threads and drops into the existing plumbing.

Should I replace the o-ring at the same time?
The complete cell arrives as a sealed assembly, but inspect the union o-rings in your pipework. They are inexpensive and are the usual cause of a leak after a cell change.
