water heater keeps blowing #2 fuse

[twertsch]

Hi, our new 2020 Kodiak Cub 175bh keeps burning out the #2 fuse every time I use the hot water heater. Doesn't matter if I am engaging the gas or electric to heat the water. I put a new fuse in, and I can turn the hot water heater on twice, maybe three times, and then fuse will burn out. If I replace the fuse, it may or may not engage the hot water heater again. If it doesn't I have to pull the fuse out and push it back in, then it will work. The dealer says there is nothing wrong with the control board, but I am skeptical as it seems to be the only mechanism that is a common denominator for engaging either the electric and gas heating option. The dealer replaced the temperature sensor. The water heater engaged on both electric and gas once, then a week later, I tried gas and #2 fuse burned out asap.
Anyone run into this problem? Any ideas what is going on?

It tries to fire? After the third time, the fli light comes on. That part sounds like it’s working. There is a way to reset the board

So its been an educational week. Never thought i'd want to know so much about a water heater! I found some videos, all by the same guy MyRVWorks.com, that i'm linking for others in the forum too. Hopefully they will help others out too. Mr Foley - This one is for you! - you are so lucky you get the clicky clicky but no ignition -
