RDspaguy Posted April 12, 2020 Report Share Posted April 12, 2020 Did you get something wet? Give us some info about your spa so we have an idea what we are dealing with. Brand, age, voltage, etc... Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted April 12, 2020 Report Share Posted April 12, 2020 They stopped making the mark 3 in 2007 from what I can find. Here are the available owners manuals. https://www.thespaworks.com/sites/default/files/hydro_spa_-_mark_iii_series_2006-2007.pdf https://www.thespaworks.com/sites/default/files/hydro_spa_-_mark_iii_series_2003-2005.pdf Does it trip immediately, after a few seconds, or longer? Can you post a pic of your control box with the cover off? Quote Link to comment Share on other sites More sharing options...
castletonia Posted April 12, 2020 Report Share Posted April 12, 2020 If it trips immediately, my guess is the heater, unless you got something wet when refilling. Quote Link to comment Share on other sites More sharing options...

These have a blower as well if I am not mistaken, which could also cause an immediate trip and could have been shorted by overfilling if the check valve is bad, which it is if it hasn't been replaced. A flooded ozonator can also cause it, but that would have been an option for that tub so he may not have one. Quote Link to comment Share on other sites More sharing options...
