R29 S Water Heater Circuit Breaker

[Bruzer]

I recently replaced the Isotemp Spa water heater in our 2020 R-29 S LE, HIN 1300971. The gasket had failed on the front of the tank and was leaking water into the mid-berth area. After refilling the tank and checking for leaks (there weren’t any) by pressurizing the system with the water pump, I started the engine to check the circulation of the coolant. I added some coolant to compensate for the coolant lost when disconnecting the hoses from the old tank. The engine coolant produced hot water at both the galley and head faucets. After plugging in shore power, I noticed that there was no light on the water heater circuit breaker panel. I assume that the AC current is not reaching the water heater. Is there a fuse between the shore power cord connection point and the hot water heater circuit breaker? If there is, where is the fuse and what does it look like? If not, would pressing the reset button on top of the thermostat close the circuit and allow the light on the circuit breaker panel to come on? Any other advice would be greatly appreciated. Thank you.

There is a fuse on the hot water heater. You will need to remove the front panel on the hot water heater.
