Hi, I'm new to this website, but it looks like it could really help me get the most from my pool - which is 8 years old and getting to need expensive maintenance! I have a Zodiac Clearwater LM2-30 SWG which has always worked well and still pumps out the chlorine fantastically (although it's on its second cell). Problem is that the controller is playing up and running the pump/chlorinator constantly whenever the controler is powered up. Has anyone come across this before? If so, can it be fixed? I know I could replace the controller but I don't want to do that unless necessary since the chlorination is working so well. I'd appreciate any helpful comments.
Thanks, Sherro

Have you gone through the programming to make sure something isn't turned on causing it to do that?
You could try resetting the unit and reprogramming.

It almost sounds like a stuck relay in the unit.

Sorry for slow response - been on holiday. I've tried resetting and re-inputting the settings etc. a few times. No change. The unit did come good for a while, and then started sticking on again. As you say, a sticking relay seems a likely cause.
