Hayward Omnilogic SWCG Board Burn

[hartpw]

Thank you for the assist! It looks like I have to replace my header and the Hayward Omnilogic T-Cell PCB Board | HLX-PCB-TCELL. I just have to make sure I can do a good job taking out and soldering in a new header!

Moved from here.

I have a similar problem and wondering how you resolved it. Not sure if my problem is just my salt cell or my board too. My board looks ok other than the connector. If my board is also compromised, not sure I can replace just the connector. I'll attach photos.

I just replace the chlorinator PCB board and the connector on the motherboard. I got the connector from Digi Key using part number 23-0015247103-ND. I made the repairs, but I am still getting the sensor and K1/ K2 stuck open errors. I'm bummed/

Check the back of the main board for burnt solder joints around the K1/K2 relays.

High salt causing high amps combined with some corrosion in the connector causing resistance on the pin connection all causing heat at the pin.

I have never had high salt according to my readings. I'm usually low in salt, so if the high salt acts the same as low salt, maybe that's why my chlorinator PCB board and connector burned.

How do you measure your salt?

When you repair or replace it, it may make sense to apply dielectric grease to the connector each year at opening. If you already have some silicone grease for o-rings, that will work fine too.

I’ve seen some folks now and then hesitate to use dielectric grease because it is, well, non-conductive. The grease won’t affect the connection, it will only prevent corrosion.

Connector grease does not interfere with conductivity. Our test tutorials demonstrate the conductive and insulating properties of NyoGel® 760G.

I usually use the OmniLogic app, the Guru app, and visits to the local Monarch Pools store to have them check it for me using their high-speed, low-drag circular reading gadget.

Ah, I didn't do that, guess I'll find out the hard way! Thanks!!

I replaced the tcell 940 and it is now chlorinating and all the alarms have gone away. For now, it seems the solder job for the PCB board was only one of two problems I had to fix to get the salt cell working.
