This unit shuts off on a regular basis. It need to go back. I didnt spend ten grand to constantly get out of the tub and flip the breakers. If I increase the water 1 degree it shuts off. Did it almost right away. If I run the jets it shuts off.Its not relaxing its a headache. Who like something that doesn't work as expected?? The tech argues with me that the issue is caused by us using the tub as we are adding detergent residue that is clogging the filters. So I get a pair of my sons shorts and place them in about two quarts of water and swooshed it around and no bubbles no foam but they claim this is causing an issue in hundreds of gallons of water. Please. After this then the tech replaced some parts on the heater saying it was not calibrated correctly. Should have done that first instead of blaming the people for using the machine like it was intended. This has been an issue since June when we purchased it. They need to do the right thing and take it back. Terrible purchase. I have asked them three times now dont send someone to the house without an appointment, German Shepard in a fenced yard. Need I say more. Again yesterday after telling them I want it returned they send a tech out. No respect. Make an appointment please. Terrible disappointing purchase. This filter has been cleaned by them 3x and by me 2 or 3 x since June. We maybe use it 1x per week so the claim of the detergent clogging the filters is just a scapegoat. They don't seem to mind us being stuck with a bad unit. I want my 10 grand back and they can pick up this problem. Going to file in district court and let a judge decide if they continue to stonewall me. May be a bad unit or a bad design but either way I'm not going to be stuck with it and play kick the can down the road.
