We recently bought a used tub, and its a good one overall, problem is we have no idea what it is and neither did the people we got it from. It has a leak, which we can deal with eventually. However, it continuously says Plumbing Error off and on for a couple of days, and then for a few days it will be find. We found the error code online and it says sensor one and sensor 3 are plugged in incorrectly and need to be swapped. I have no idea where these sensors on, nothing like that is labeled.
Also, I really hate to say this, but I have no idea how to post picturs on here. I know how to do it using a URL, but I only have my phone and my computer is out of commission. If you think you can help me feel free to reply and I can try to get the pictures to you through email or something.
