Hey, nice forum. I just stumbled across it and can't wait to post my questions and answers I may have since I can fix almost anything but water heaters... My problem is a EG250 Laars Teledyne spa heater's pilot won't stay lit. The pilot will fire up, heat the generator/thermocouple to plenty of millivolts (800) but every time I let off the starter button, the pilot goes out. I've already replaced the generator because it was the most obvious and cheapest, and retested and the pilot won't stay on. I'm thinking about replacing the gas valve assembly, but figure I need to test the high temp sensor as well as the thermostat to ensure signals aren't getting cut somewhere in the loop. I figure they all need to be working for the gas to kick on, but since the pilot won't stay lit, I thought the prob. is with the valve assembly and not anything else. (If the sensors were shot the pilot should still stay lit but the main burner wouldn't light right? ) Any insight any of you may have would be so helpful. I hate paying fix it people and I like fixing things myself. Any ideas on what to check for and how to check?

I have an aquarite chlorine generator that was professionally installed 2 years ago and has worked great! Recently, the red "no flow" LED has been lit constantly (not blinking). I checked the connections and they appear intact. I removed the cell to get a look at the flow sensor and it appears to move freely and isn't blocked by anything. I called the manufacturer and they said I'll need to call a service tech and that it's either a bad sensor or bad computer board. I took out the sensor to get a look at it and I'm not really sure how it works because it appears that the metal paddle has no other metal connection to touch for the sensor to recognize there is flow. It appears that the flow pushes the paddle up against a gray plastic backing. Also, something I forgot to mention to the manufacturer. I haven't been adding salt over the winter so I know it's VERY low due to dilution from rain. Does the water need salt in order for the flow to register? I thought it might have to so with the NaCl conducting a current through the flow switch. Has anyone else had any problems with the flow light or flow switch?
