I've got a unknown manufacturer of hot tub, but I do know it uses a Leisure Bay Industries control box.
Here is a pic of the heating element - the only nomenclature on it is a model # 80-0103.

Does anyone know what kind of element this is and where I can find a replacement?

Thanks!

either the EHEBRT101 or EHEBRT105B

Thank you! I'll check those sites and see what I can find out!
