We own a Dimension One Journey Spa and have three flashing red lights on the panel on the hot tub. We read the manuel and have replaced the filter now and reset the breaker and still have the lights. The heater worked for a couple weeks with the lights on but now won't work any longer. The pump works well because the water is moving and everything else seems to be working well. We have opened the hot tub up to see the control panel and have a glowing red light. After some research it says the pressure switch or the high limit switch needs to be replaced? Can anyone please provide any insight on this we are desperate.
Thank you
