I too have had a less than pleasant experience after purchasing a Great Lakes spa. I have owned a spa for over 30 yrs. This is my 3rd and by far worst. GL spas are assembled very poorly at the factory and contain various defects. The factory warranty covers only parts, no labor or trip fee.
I wish too that I had taken the time to search the internet for customer reviews before purchasing this lemon of a spa. My spa has leaked (and still is) since the inital fill. A plastic tubing ( ozonator line) was supposed to be plugged and wasn't. Guess what?? I start to fill the spa for the first time... check for leaks... looks good. I check on the water level later... the tub is 1/2 full and water leaking on the floor from under the spa. I already had the door off by the pumps from the electrician wiring the tub. I could see the source of the water leak.... but where does the line go??... call the dealer... no one answers... off hours... can't get in position to see behind the pumps w/o a hand mirror... so I pinched it off and quit filling it. After calling the dealer after the weekend... he says the line was only to be used for an ozinator, which I didn't have on this particular spa. I stick a 1/4 in. bolt in the tubing and double clamp it to seal it off... Leak fixed.... so I thought. Several days later... after mopping up water every day, I call the dealer again. He comes out and removes all the side panels to find a leak in the PVC tubing at a glue joint. The stereo didn't work either.... antenna wasn't hooked up. I have 2 service trips that have been charged to me for $75 per trip... which I say isn't right and the dealer refuses to work on repairing the PVC leak until he receives payment for the previous "service" trips... At this point of time, I dial the customer service hotline... They are sorry to hear my plight... but not sorry enough to admit that they screwed up at the factory and offer to make it right... They should put a "Buyer Beware" right below the Great Lakes logo.
