OVERVIEW
The CaliMar® CMARCHA40-1Y salt cell is a generic replacement for the Hayward T-CELL-15, meant for use in Hayward Goldline AquaRite, Aqua Logic and Pro Logic salt systems. CaliMar® replacement cells are proven to provide reliable performance after being tested under rigorous conditions. We are proud to offer these products to our customers as a more economical alternative to OEM (original equipment manufacturer) models and other generics.
 
If your Hayward salt system was built prior to 2009 you can use an OEM factory T-CELL-15 or generic equivalent like this replacement cell. Replacement salt cell CMARCHA40-1Y is compatible with Hayward systems made before 2009. If any of the following applies to you, the CaliMar® CMARCHA40-1Y replacement salt cell is the proper generic replacement cell choice for your Hayward salt system:
  • Your system was made prior to 2009 
  • Your pool is larger than 25,000 gallons in volume 
  • You are replacing a T-CELL-15 salt cell
The CMARCHA40-1Y is a plug-and-play unit, meaning it fits perfectly with existing plumbing and Hayward equipment, replacing the T-CELL-15 seamlessly with no additional installation or plumbing required. It is designed to chlorinate pools up to 45,000 gallons in volume. It comes with a 15-foot cord, providing flexibility in connecting to your existing power center.

Can this product, CMARCHA40-1Y is a direct replacement for Hayward T-CELL-15, be used if my system was made in 2009 and not before 2009?
A shopper on Jul 5, 2021
BEST ANSWER: Sure, just make sure your AquaRite is set to the correct cell type
my revision come up as r 1.59 is it compatible?
Dana F on Feb 12, 2021
BEST ANSWER: Yes, for revision 1.58 and later, multiple different cells can be used: T-3 up to T-15. Make sure your AquaRite is set to the correct t-cell, T-15 in this case
Will this work with software revision r 1.40?
Erin E on Jul 11, 2020
BEST ANSWER: Yes. Select AL-0 in the diagnostics settings.
Ask again will this work with software r1.4 ?
A shopper on Feb 9, 2021
BEST ANSWER: It is true that a T-15 CAN be used in any AquaRite regardless of software revision, but 1.40 and earlier might be set for T-5 or T-15. If the board setting and cell type do not match the system will not work correctly. For 1.58 and up it can be used, but the cell type must be set to match in the diagnostic menu.
The CMARCHA-1Y have the tread on it or tread whith the lock nut?.
Milano on Jul 2, 2020
BEST ANSWER: Tread? It has threads on it for the locknut to screw on it
Can I use this cell to upgrade from a Hayward T-Cell-9, using a Hayward control panel with Version 1.5 software for a 15,000 gal pool?
A shopper on May 12, 2022
BEST ANSWER: As long as the control panel is capable of switching to from a T-9 to a T-15; this programing process can be seen on U-tube; very simple process.
Is it compatible with Hayward AquaTrol Salt Water System? Thanks!
A shopper on May 4, 2022
BEST ANSWER: Yes it is. I would suggest you buy the longer warranty. My cell only lasted one year.
Will this work with the Hayward SwimPure Plus salt system?
A shopper on Mar 9, 2022
BEST ANSWER: Yes. This cell works on all Hayward salt systems up until 2021 unit
will this cell work on a 2015 system with a original t cell 15 ?
jerry on Oct 31, 2021
BEST ANSWER: Yes. It worked for me.
My software is version 1.45. Many replacement cells require software version 1.5 or higher. What are the requirements of this replacement cell?
A shopper on May 25, 2021
BEST ANSWER: It’s not true that only T-15 can be used or that T-15 will always work in older units. T-5 was the default for some units instead of T-15. You can use either, but the board jumper must be set for the same type. Unless you had a T-5 that was undersized for the pool or you can’t find a T-5 (getting rare), use the same cell type as the one you’re replacing.
Will this work on a pureline system?
A shopper on Apr 22, 2022
BEST ANSWER: Possibly, but likely no. IF the PureLine control box was used to replace an AquaRite AND the Hayward spec cell was used, then this cell will fit, but may not perform as expected. Most likely you need the PureLine cell PL7700
Does anyone know if this will fit the Pureline Salt System?
Kristen R on Apr 8, 2022
BEST ANSWER: Not for a stock unit. This is equivalent to the PL-7106. You would need a PL-7700.
I have an Aqua Rite generator reading "hot" 157 degrees, and not generating choline. I sit the cell or is it the generator?
A shopper on Oct 7, 2021
BEST ANSWER: Most likely the temp sensor (thermistor) in the cell has shorted.

Pool supply sent the wrong product. I have called multiple times as well as emailing. They have never responded. I have had to turn the matter over to American Express to get a reply.

Working at the moment, but touch and go
Giving this three stars for now. It’s been a bit flaky but currently generating. The salt level is 3600-3700 depending on water level, but the cell indicates 4400-4500. Current is above range high, but not quite high enough to cause a high salt shutdown. It has done a low salt shutdown a couple of times when it was reading 0 salt instantaneous and dropped to 2000 ppm average. Hopefully it settles down after awhile.

Works with Goldline Aquarite r1.33
I seem to have older firmware than anyone else I've seen post online. My control unit is from 2004 and running r1.33. I picked it up used on Facebook as a backup and installed it today with the Calimar Cell. Power is on and it is Generating chlorine.

Also, salinity and other readings from the cell are accurate. If you have an older unit they are hardcoded for T-15 cells, i.e. no option to select cell size. This cell is working fine after several hours. That is the best I can confirm for now. Hopefully get 2-3 years out of it.
