Customer Question

I'm working on a Freeflow Passport spa. I opened the panel for the pump and electrical and there's a black soot all over everything. Where would this be coming from and how should I clean it?

My name is***** do my best to answer your question.
If you are seeing this soot INSIDE the control box where the circuit board is, you most likely have a problem somewhere on the circuit board. Usually a heater relay will go bad before other things fail that would cause soot. Often times when that happens, soot will show up in the box, particularity on the back of the back cover where the white schematic label is.
I would need to have eyes on what you are describing to advise you more. If you would like to send some pics, I will look at them.
I just use a towel and dawn or normal spay cleaners on the hard surfaces. A Mr Clean magic eraser does wonders on the labels and works very well for cleaning the tub shell, also.

Thanks. It was not in the control box but in the pump enclosure. It seems to be just a carbon build up coming out of the pump motor. That being said, there's also a broken pipe/connector that has to be fixed so I'm not working on the pump for a while.Thanks anyway.

Since the soot is in the equipment area and not the control box, I would suspect the blower motor before I would a jet pump.
Maybe this is the pump motor you refer to?
Usually when I get asked about strange soot or black marks it is a relay on the board that has blown out. Sorry for the misunderstanding.
Jet pump motors do not give off soot,not that I have seen. However, sometimes when a air blower(bubbler) goes bad, the brushes and foam insulation inside them can get quite messy.
I am sorry about your pipe issue, I hope it is simple. If you would like help with that send me some pics and maybe I have a repair suggestion or know of a repair fitting that will make it easier.
Also, if you wish to include pics of the soot, I can suggest something to clean that up with.
