Hello all,
This is a great forum and thanks to all the posters.
Went to turn on the hot tub the other night but no joy. The Raypak display had SPK. If I turned the heater off/on, you can hear the unit clicking (as if trying to light), I believe CFH displays briefly, and then SPK. I can then smell just a bit of gas.
The manual tells me SPK is for spark which I assume to be part of the lighting sequence. Does anyone know if SPK means the pilot or related electronics is/are bad?
Thank you in advance.
Brian
