When the motor comes on, is it actually running or does it sound more like a humming, which is what they do if they're seized up.
Can you snap me three pictures, one of the display you're seeing on the topside, one so I can see all the equipment down below, and one so I can see inside the control box down below where the circuit board is. Then I can wall you through some troubleshooting. Thanks, jeff
ok, thanks, Jeff
ok, It's just much easier when I can see what we're working with, and you had mentioned yesterday that you'd have the pictures today, so I was just responding to that. First off, I don't know if you have a 2 speed pump that's running the heater, or a small circ pump as sundance has used both. If you have a small circ pump, and it's not coming on, then that will trigger the dashes on the topside and immediately shut the system down. The dashes are a very generic error code and can also mean a bad temp or high limit sensor. Those can be tested with a meter set on ohms and they both should read within 1k of each other with water in the tub. Yes, it can also be a short in the main motor, but we'd need to put a clamp on amp meter on the wiring to the motor to see what it's pulling when it starts momentarily. I only ask for the pictures as even if I throw out all of the testing information, most people still have no idea where or what to test unless I can see it and point them to it, otherwise it's all jibberish to most people. Yes, go ahead and try unplugging the pump that's stopping, but if it is a 2 speed pump and it's feeding the heater, then you're not going to get heat either. If it has a small circ pump for the heater, then we need to see if it's getting power to it as well.
And i'm sorry about asking question, but when I'm not sitting right in front of a spa working on it, it's like troubleshooting with a blind fold on, so asking questions is the only way to troubleshoot from this end. Unfortunately there's not very often a solve all answer I can throw out there and fix the problem, it always will involve questions and answers from both ends of the conversation. Thanks, Jeff
Justchecking in to see if any of that info got us any further on troubleshooting the issue. Thanks, jeff
Ok, at this point we need to test the sensors to make sure they're not the problem. You'll need to test both the temp and high limit sensors with the meter set on ohms and let me know what they both read, aswell as the current water temperature of the spa when you test the sensors. I don't see a picture of the inside of the control box with the circuit board, so I can't really point out the sensors to you yet.
Ok, sensor harness is at the top of the picture where the board says sensors. Flip the two grey locks out to the right and left to unlock the harness from the board. One of the 3 sensor wires goes to the pressure or flow switch, we don't need that one tested just yet. Follow the other two grey wires out of the box so we know which one is which. The one that goes to the heater is the high limit sensor, the one that goes over into a tube towards the filter chamber is the temp sensor. Once you've identified them, hold the harness in your hand, meter on ohms, touch the two test leads to the black and red going to the temp sensor and record the resistance, then do the same for the high limit, then we need to know the temp of the water. With those three pieces of info, I can tell you if they're reading correctly.
Just following up with you to see if we had found out any further information. Just let me know. thanks, jeff
