If you'll look at the bottom of the page, there are a number of threads reporting similar problems. If none are relevant, post again, and I'll ask PoolSean to take a look.

Thanks for the info. Looks like thread 23752, the first one in the list is my exact problem. Didn't clean the ends of the fuses so will try that and hope that I get the same results.

Thanks for your time in creating and managing this site, very helpful.

Well, that didn't solve my iussue, no joy here. Cleaned all three of the fuses and still getting the same readings. Also checked the other connections and no corrosion on any of them.

Let me make sure I understand:

1. The cell has been in service for 4 years.

2. The only fault is lack of chlorine production.

3. You have occasional, or regularly, used the BOOST mode.

Is that all correct?

If so, is there reason you aren't thinking that the cell is simply at the end of its life? Are you aware that SWCG cell life is pretty much a straight forward function of "ON" time? And that BOOST mode results in significantly reduced cell life?

[pacsman]

Yes, all is correct. Last year due to the conditions in our area we did use boost more frequetly than in the prior years. I am aware that the life of the cell is limited but wasn't sure how many years I should expect to get from normal use. Having looked around on the internet for others with the same issue, and finding all sorts of reason that the unit may not be functioning, I didn't want to just order up a cell without exploring/investigating all the possibilities.

I also have a church friend whose neighbor uses the same system and was getting similar (not sure if it was exact) messages and it turned out he had three bad diodes on a control board. Once he had the board repaired all was well. Again, I dont know if he had any Voltage or Amperage reading, just that he had the same warning message.

It does appear that my issue may just simply be the cell is at end of life and I need a new one. Just trying to cover all the bases.

So your recommendation would be to purchase a replacement cell? Appreciate your time and feedback.

1. Purchase the largest cell that will fit with your system -- a 10,000 hour unit will last 2x as long (in years) if it's used 1/2 as much.

2. Never, ever use BOOST. Use a gallon or two of bleach, instead.

3. Only use your SWCG for NORMAL pool operation -- not for start-up, not for algae, etc. If something's wrong, understand it and fix it manually.

AutoPilot is by no means the worst, but like most 'new and improved' or 'digital' pool equipment, it is often oversold as a complete solution, when in reality it is just a tool with limitations like every other tool. Quite a few people here think the AutoPilot is the best SWCG, but it's still just an SWCG, with all the limitation inherent in the technology.

What SWCG's do well is consistently chlorinate pools that are experiencing normal loads. What they don't do so well, is everything else.

my Autopilot cells have lasted around 4-5 years. I use the SC-36
