This is a great board ! It is amazing how much information I found here.

I am having problems with my Pool Pilot system after returning from vacation. The pool was green and the control box showed 3 flashing lights.
Actions taken:
- Cleaned the cell (It was fairly dirty and after cleaning it looks like new)
- Cleaned the sensor (just in case the readings were off)
- Added shock, salt and acid in an attempt to restore to the chemical balance

After all this, there were still 3 flashing lights. Next step was to verify the control box:
- Doing the Diagnostics, it showed no voltage and minimal current

Verified the fuses and found the ceramic fuse to be faulty. Replaced the fuse.

The indicator lights now flash twice (at least a difference). The Diagnostics show active voltage and current.

Please advice. Is my circuit board broken?

Check the cell's cord, especially the connectors.

Thanks. I rechecked the cord. It is about 2 years old and it was replaced with the last cell.

All connectors are clean and connected solid.

Verify your salt level.

I had the water checked last week and it was recommended to add to bags. The salt level is about 4000 per the reading of the diagnostics.

The situation has actually changed over the weekend. I also added 4 pouches of shock to be able to see the bottom of the pool again. The water is clear now and the service indicator light switched off. Does this mean the machine is functioning again or is there enough clorine that it does not need to generate anything?

So, did you have an opportunity to verify the salt level? Your diagnostic display of 4000 ppm may need to be calibrated. Adding two bags of salt and seeing the error message go away CAN indicate that you're actually low on salt.

I just checked at the store and the reading is 3500.

The double flashing light is back.

Ran the diagnostics again:
Salt indicator is 4200
Voltage is now 14
Current is 45

I'm assuming you mean 4.5 amps for the current.
Are you on Cell Power 1?

This is basic, but, did you check your cell for scale formation on the blades?

If you're comfortable with a voltmeter, verify the voltage to the Soft Touch.
