Question about Autotrol 263/740 Performa Logix Control Valve

1 Answer

What is wrong with my water softener Autotrol 740 Electrical problem?

I have a Autotrol 740 water softener that has an electrical problem. The transformer was blown, so I bought a new transformer and a new timer board. Installed them and the softener worked for 24hrs. After that, the transformer got blown again. I measured the outlet and it's ok. I am told that the timer motor on the softener could've gone bad.... Suggestions please!!! Note; this all happened after a few lightning strikes close to where I live.

If there is a bridge rectifier or diodes directly down line of the transformer i would suspect it is bad.. put an inline fuse also on the primary side of the transformer and wouldn't hurt to put a fuse on the secondary also if the transformer only has two wires for the secondary..

Softener is making slight grinding type noise working ok

Either it's getting old and you should start saving for a new one or you need to find a local water treatment dealer who is a Certified Water Specialist (find at to get yours rebuilt. If it's 10 years or older it will likely be cheaper in the long run to replace it. The softener with the fewest moving parts and the longest frequency to first repair also has the longest factory warranty on the electronics and valve: Autotrol.

Autotrol 1550 tc manual

I've been an Autotrol dealer for 25 years and this number is unknown to me. You will find a model number on the back of the microprocessor or timer... like 255/460i or 268/762. For a manual, go to choose your valve; either 255 or 263/268, select Resources , open your manual and download.

Error Code 1

The fastest I ever saw a Kenmore softener thrown in the dump was seven weeks old. This was at the owner's insistence; just wouldn't remove iron. He bought an Autotrol with a turbulator from me. This was about 15 years ago and it still works just fine. He had his first service call 2 years ago. I've always thought that quality was more important than price, but if you wish to install yourself I can come so close to the "sale" price of a Kenmore.

Sestem is not using up salt and will not flush the lines when it is set up to .

Hi Joey,

There could be several reasons why your softener is not using salt. If it has a Demand Control the turbine that meters the water may be blocked and stuck so the softener doesn't realize that you are using any water, so it won't try to regenerate.

Your injector may be plugged, although this would cause the salt tank to become more full with each regeneration.

If you initiate a manual regeneration and regeneration does not happen you may need to replace the softener.

Knowing what make, model and age of your softener would help greatly in assessing. The best quality softeners last 15 to 18 years unless you have an Autotrol Turbulator in your softener, in which case add 25% more time; 19 to 23 years. There are a few brands that don't seem to last longer than 10 years...

1990 volvo 740 GL. If you have electrical starting problems whre do you begin and end with troubleshooting. I have cleaned all the connections on bat terminal, changed out the 2 black 40 amp relays....

If you haven't changed the fuel pump relay, that will be the problem.
It's the one on the right side behind the ashtray.
Hope that sorts it out for you.

1991 740 Wagon electrical problems

Was the car primarily in a Southern state--no winters? If yes, it could be the wiring harness that leads to the rear wiper/stop light inside the rear tail gate. They usually break at the flex point, and short to the frame.
