T-CELL Voltage Sensor Short Chlorinator1

Ok so it sounds like it is turning on but then there might be a short between the SWG power leads. That could be due to the other relays (K2 & K3). K1 connects the AC power to the rectifiers and K2 and K3 swap the plus and minus leads to change polarity. If one of the relays changes but the other doesn't, then there is a short although, I would have thought that the fuse would blow under that condition so I am not entire sure that is the cause. Another possibility is the sensor that measures voltage between the +- from the rectifiers. The problem is these boards are not all that easy to fix or troubleshoot. The only thing that is easy to fix is a bad solder joint on K1 which is the usual culprit of these types of problems. K1 has three leads that you can see if you turn over the board. If there is a problem there the solder joint might look burn and/or dull. You did check fuse U correct?

My board shows K1 and K3 relays differently than marked in your attachment above. Your K1 & K3 should be swapped. Boards are same rev. See below:pix 1.jpg

The labeling doesn't really matter. The top relay is for power. The bottom two are for polarity.

But again, I would not attempt a repair if the board is still under warranty.
 
But again, if one of those two relays was inoperable, the + & - would short and blow the on board fuse. So a blown fuse would need to be a symptom as well.

Hayward should take care of the board.
 
mas985 you are correct. I replaced the board and did a backup and restore. The system appears to be normal but when I do a shutdown at the panel, not the app, it hangs with "???" displayed. I also discovered a clone backup/restore procedure. I wonder if I should do a clone restore instead of a normal backup restore. The backup did restore my network settings and all network diagnostics pass.
 
Try a factory reset first and see if the shutdown does what you describe.

Next try the clone/restore. If the problem persist, then you might want to try a factory reset and reprogramming the unit from scratch. A bit more work but sometimes the configuration files can get corrupt.
 
Mas - the restore from backup and clone did not work. The sensors and relay mapping was off. Took your advice and did a full edit from scratch. That seems to have worked. All is working now -yay! Will see if the K1 K2 horror goes away. Thanks again.

No, nothing has been resolved.

I have been working with Hayward support on this for OVER A MONTH NOW. They are giving me a runaround. First they told me to go to their web site and look at the list of "authorized" pool specialists that can service Omnilogic. They had about 8 companies in the list within a 25-mile radius, I contacted every single one of them. Most did not even bother responding. Out of those that responded, most said they either dont have a clue about what Omnilogic is or they dont service is. This means Hayward is giving out this "authorized" status to random pool companies without bothering to check if they can actually work on Hayward products. What a shame.

After the "contact authorized pool professional" fiasco, I contacted Hayward again. Their regional rep (I was not given their name) provided me with a contact of a company that allegedly services Omnilogic. I have called them and tried to make an appointment. They asked me for some info (Model and serial # of the Omnilogic, etc) and then stopped responding. I am now back to square one - emailing Hayward (there is NO phone support) and waiting for 1+ week for each response.

I now realize that Hayward is one of the worst companies I ever dealt with. They do not stand behind their products and what's even worse - they don't actually have anyone in the field that can work on their pool automation systems, at least in my area (NYC). So...one of the biggest pool equipment manufacturers in the world does not have ANYONE that can repair a system that has been in the market for over 5 years, in an area with a population of over 10 million people. Let that sink in. This is mind boggling.

Anyone considering Hayward products for their pool needs to read this and know that when (not if) things go wrong, they can count on Hayward leaving them high and dry.

I realize this is an older thread from last year but I am getting same errors now after a two week old OmniPL Upgrade Kit installation. Just wondering if Hayward ever acknowledged a problem or solution?
My system has the latest firmware out as of summer 2022.
 
Just an update on this issue. Hayward Tech Support is telling me to go BACK a version of MSP firmware.....so from the latest 4.41. to 4.4.0

Seems odd to me but I will try
