Water Heater Fuse 2015 400QL

[caflorin]

Need location of my water heater fuse. I have no 12 volts at the switch. 2015 400QL. TIA

I would think the WH is powered by a 110V circuit check the breakers.

Thanks. According to my tech man...it's all 12 volt. I did check all of the breakers anyway. I can't find a fuse that says water heater on my coach fuse block.

OK it might be you are talking one switch and I'm talking another I'm referring to the switch on the wh. If you are talking about the switch inside that powers the igniter of the gas side of the wh I have no idea of where the power comes from. I suspect it is tied into something else check all the fuses even if it isn't labeled WH good luck

What water heater do you have?

Caflorin,
if you could provide the last seven digits of your VIN# that would help. Thank you.

My VIN: CFW8260

Would still like to know if there is a fuse. My meter had a bad lead, so the power was there all along. I chased the power back to the relay, but the unit would still not power up. It acted totally dead. I took a chance that the water flow switch was the issue. It read good on the meter, so I cleaned up the relay and ground connections. I am back in business. Thanx all for your input.

It's a GIRARD tankless. All 12 volts single source input. Igniter uses a transformer on the circuit board to step up juice to the igniter.
