Rated 3 out of 5 by from Great Hot Tub, Filters cause air locks I will say I do love my spa, but the filters are always causing air locks, even brand, new clean filters, in a few days I get an air bubble and it stops heating and circulating. This is especially annoying in the winter because I have to go out and keep fixing the air lock for fear the temp will drop to freezing. I have completely drained and refilled the tub and put in all new filters and it happens over and over. Other than that, it is a great spa and I do love it.

Rated 3 out of 5 by from Problems with holding water I love the hot tub itself. The jets are wonderful. Unfortunately we have now had 3 service calls because the tub is losing 2 inches of water a week. Each time the foam has to be removed. The dealer has taken weeks at times to respond.

Rated 1 out of 5 by from Nothing but problems I have owned a hot tub all my life. I know how to maintain them. My last one lasted 15 years with no issues. But needed something bigger. I went into a highly recommended business and asked for the best money could buy. Worst decision. It locks out on dry pump constantly. My filters are new. I have used many different filters trying to get it to work. My dealer has been out numerous times and no remedy. The bluetooth is a known joke. The wifi has never worked right.

Rated 5 out of 5 by from MPL 900 - Great Hot Tub Wasn't looking for a hot tub but stumbled on this Mac Daddy during a visit to a trade show. Loved all the features and the number of sitting areas and multiple jets in each location. Was easily installed and up in running very quickly. All the controls are easy to use and simple to understand. The sound quality is A+++. The family uses it constantly and is well worth the value.

Rated 3 out of 5 by from Master SPA is ok We wanted a Master SPA since the one we had back east worked for over 15 years and had little problems. We bought a new one on the West coast and learned if you want any warranty work done you have to pay $90 for someone to come and look at the issues. The sun has warped our skirting and have WIFI issues and rust on speaker screws. Other than that, it works as expected.

Rated 3 out of 5 by from Nice Spa, nothing but trouble though.... The hot tub is nice and large for groups and entertaining. However, we continue to get air locks like others have complained about. We have trouble with balancing the water constantly. Have had to drain and refill my tub constantly, have had a technician out to fix the heater that's gone out several times. Had to replace the speakers, all the jet controllers and all the speakers which was not cheap and all this happened just outside of our warranty period. All started with the heater blowing the breaker constantly right after it was installed. Found heater was bad. Easily replace but service took almost a month to get to it. Got heater fixed but within 4 months started having heater issues again. Took another month to get it serviced after our service call. Had to order the heater core. Then chemicals got out of hand and burned all our internal equipment - techs blamed us for the chemical imbalance. Constant issues - more than I expected. I owned a pool for 7 years and never had these issues. Was told a hot tub is easier to manage than a pool - not so much.

My hot tub screen says over heat how do I get back to the main screen 

Asked by: Emilio32
There should be an “exit” button at the bottom of the screen or a “back” button in the upper left corner. If you don't see either of those it might be a good idea to contact customer service.
