SALTCELLCHECK Find my model

Your salt system is telling you something. The listing selling you a cell is guessing what.

A warning light on a salt system usually means the water rather than the cell. Which replacement cell fits, and whether it is still covered, is decided by three things no listing prints: which controller you own, which part number is on the box, and where you bought it.

The light on your box

A light is on. Which one?

The box tells you more than it seems to. A warning light usually means the water rather than the cell, and the brands genuinely disagree about what the same condition does.

What the documents say and the listings do not

30

manuals, no answer in any of them

The most replaced salt cell in the country does not come with a stated lifespan. We read every Hayward manual, sell sheet and warranty document in the archive, including the French-language editions, and none of them says how many hours the cell is built to last. Pentair states 10,000 and puts a meter on the unit.

What we know about each cell, and what we do not

Searched across 30 distinct Hayward documents held here, manuals, sell sheets, line sheets and warranty terms, including the French-language editions.

5

statements, four documents

On most Hayward systems a generic cell costs you the warranty. On the AquaRite S3 it costs you function. Hayward states it on the product, its board documentation names the one supported cell family, and its service guide has a message for a cell that fails the check.

Which cells fit a Hayward AquaRite

5 separately verified statements, across 3 Hayward documents.

2

different acid dilutions

For the same job on the same kind of part, one manufacturer specifies ten parts water to one part acid and two others specify four to one. Following the wrong manual is two and a half times the acid its maker calls for.

The cleaning procedure, brand by brand

2 dilutions, each quoted from its own manufacturer's cleaning instruction, across 3 documents.

13

warranty variants, not one number

A salt cell warranty is not one figure per cell. It changes with the product line and with where the part was bought, and on one brand the term sheets and the owner’s manuals contradict each other outright.

What each manufacturer’s paperwork says

13 published variants transcribed from 7 warranty documents.

What a warranty actually turns on

Coverage on a cell four to seven years old is worth checking before you buy anything, because on more than one brand the answer depends on where the part was bought rather than on the part. One row per warranty variant, not per cell. The full cross-brand table, with every source named.
