urban Posted October 29, 2017 Report Share Posted October 29, 2017 I'm trying to run down a problem with my motor and was wondering if anyone could help me out. Long story short, I topped off my tub the other night and meant to go back out and turn the hose off after I changed and somehow forgot. When I remembered at 6 am and jumped out of bed to check on it, the water was obviously running over and the panel showed OH on it. I turned it off and let it sit for a while. I emptied some water out and a few hours later turned it back on to see what happened. It comes on and reads the temperature but doesn't start to circulate. I took of the panel and it looks like there was some dampness in there but it wasn't too wet. I feel like the first time I tried it, it clicked a few times but nothing then happened. Now, it doesn't click or anything. Just shows the temperature. If I try to turn the pump on, the light cycles like it does as you go through the speeds, but nothing with the pump. I've had to problem solve some other stuff so I did the normal things....obviously there is power so it's not a main breaker problem. I checked the terminals with an ohm meter and that seems fine. I get a reading on both terminals when tested one by one with the black probe on ground. I checked all the fuses and they get flow across them and look good. Nothing looks as if it shorted...no dark/burn spots that I can see. I even took the capacitor off and check it and got a reading across those terminals. Any ideas?

urban Posted October 29, 2017 Author Report Share Posted October 29, 2017 One more bit of information. I had an aha moment and realized that I just checked the capacitor with the wires still connected. To be sure this wasn't a false normal result, I went back and disconnected the wires and then tested the terminals. I got a quick reading that then fell to zero. Do I interpret this as a bad capacitor? I read that it should gradually build up as it is fed by the battery on the ohm meter. Quote Link to comment Share on other sites More sharing options...
urban Posted November 1, 2017 Author Report Share Posted November 1, 2017 I was just trying to bring this topic back up and see if anyone had an idea. I went ahead and bought a new capacitor but that didn't fix it. Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted November 2, 2017 Report Share Posted November 2, 2017 If there was water in the circuit board pack, it would short out, so that's not causing it to non-function. OH means overheat and usually is from no water in the heater. If you were "topping off" a working tub, that shouldn't be the issue. If the tub was previously empty and you filled it, you may have an air blockage in your pump # 1. I've seen overfilling cause water to get into the blower's air lines and work it's way into the blower causing it to short out. That doesn't seem consistent with your problem, but you might try disconnecting the blower, just to see if it's screwing up your priming mode when you turn the tub on. When you removed the capacitor and put your voltmeter across the leads, you probably discharged the capacitor. That's why you got a reading that fell to zero. You have to remove the fuses from the circuit board to test them. You can't test them for continuity while they're in because they have continuity from other circuits on the board. Try disconnecting the control panel, than power up the tub. By default, a Balboa pack will run without the control panel. If everything is working, then your topside has probably got water in it and is preventing the buttons from working. Time for a new topside.

urban Posted November 2, 2017 Author Report Share Posted November 2, 2017 Thanks, Dave. That gives me something to look into. I thought that maybe the control panel was working since it turned the light on and off. I'll give that a try as the way it was running over, the water would come right over the control panel. I was just topping off the water so I wouldn't think it would have air blockage. Quote Link to comment Share on other sites More sharing options...
