I have a Dream Maker Spa model#X4H-UHS-DMI-SD-F manufactured 2009-09-22 that is acting up. I haven't owned it long, but it was working fine before now. The issue I have is that after heating up it seems to stop maintaining the temperature. This seems like it may be intermittent.
Basically, the tub can be at 95F and be doing nothing. I hit the temp up or down button and a second or two later the jets kick on and the tub starts hitting and eventually hits the max temp. For some reason it seems to stop staying near that temperature and drops without attempting to heat back up until I hit a button again.
Any ideas on where to start with diagnosing this issue? I'm new to hot tub ownership since it came with the house I purchased a couple months ago. The filter is maybe a month old and it was used maybe 12 times with 2 people max for less than an hour at a time so I don't think it is the filter, but I'm going to try cleaning it.
