If you have a digital camera or the ability to send us photos of your controller, heater, circuit breaker box or whatever it is that is causing you problems with your spa/hot tub, they will greatly accelerate the process of diagnosis. Lastly, if you go ahead and register here with a unique user name and a real email address, you will be notified automatically when we respond to your questions, making life a lot easier than having to come back and weed through a lot of "Guest" posts, trying to remember what the subject line of your topic was. Sometimes we will change the subject line of the topic you started to a format that allows others to view them in a more organized way. For instance, a new topic with the subject of "Breaker trips when I turn on jets", will be changed to "1998 Cal Spa - Balboa 2000: Jets trip breaker". If you can come up with something along this line it will also simplify our task of keeping the forum more organized. Thanks! PS: Serial Numbers of Spas, Pumps, Controllers, and relays and such do us no good so that's one less thing for you to worry about!

I have the HL flashing on my spa after it heats up it shuts down the hl sensor has a adjuster on the top will that help solve this trouble or do i need a new sensor i have just replaces the heater with a 5.5 is a 230 volt

I have a Dimension One spa, 1999 or so, that is having the display blink (all indicator lights), and the temperature shows around 105 or so. I am pretty sure that the temperature is not that high. A message tells me to clean my filters and check the water level. I did both and everything's okay. Then it says to restart. I did that and the blinking continued. I removed the filters to clean them and then the blinking stopped (maybe because the temperature reading went down). I started the pumps, and the blinking came back on (without the filters being installed). It appears that a sensor in the heater is showing high temperatures. Is this because of a blockage, and if so, what could it be? For safety sake, I have turned the system off for now.
