I have a hot springs 2002 Highlife hot tub. I noticed a dripping coming from the end of the heater unit. I turned off the power and removed the end cap off the heater assuming I would need to replace a gasket or O ring, I found that the end cap had a small crack between the 2 holes. After finding I had no other option to replace. While waiting for the new haeter, I put the heater back together because other than the small drip it worked fine. But now after I turn on the power after a minute or 2 the red and green lights blink. I put the water hose down the gray filter tube to be sure to get rid of any air, tried this a few times still get blinking lights. Now I can't get the water heated and worried with the cold temps while waiting for the new part!
