As I said earlier I am new to GMC's so here's my question I fill the water
tank (full) flip the switch for the hot water heater, I am plug in a 15 amp
recep, had it on for over 1 hr and no hot water. What am I doing wrong.

*Thanks *

The breaker in the circuit breaker box might not be turned on or perhaps someone turned on the water heater without water in the tank and burned out the heating element.

Mine has a overtemperature circuit breaker under the front cover on the water heater.
The high temp of the engine coolant which heats the water while you drive can sometimes trip this breaker.

I drilled a hole in the cover plate in just the right spot to be able to insert a plastic Bic pen and push the reset.
Otherwise you have to remove the cover to reset it. Make sure the 110V is turned off when you go to remove the cover.

Bill,

There is a switch to turn off the power to the water heater and some models have a dedicated breaker. There are three locations for the switch and
that is just for the GMC fit coaches built in 73, 74 & 75 and 23 & 26ft. So, if the coach is one of those, then you only have to look in the
electrical space, under the sink in the head and under the galley sink for a switch. Then there is the question of if a by pass has been installed to
facilitate winterising. You will have to find that out on your own. But, before you work too hard take a test light into the water heater and make
sure that there is 120VAC at the controller.

I would start by going in to the breaker panel of stock coach and using an amprobe to see if it the heater is drawing power. I don't know if you
have or can borrow one of those.

I found out a year into owning mine with no working hot water heater that the tank corroded fully through the heating coil loop from the engine
through to the supposedly potable water tank container, and THAT had corroded out the bottom. I had unhooked both fresh water to it and electrical (at
the fuse panel, because with just the white wire and not even the black wire at the panel it would trip a GFI feed from my permanent house because
corrosion can ground the element), but the final result/bad sign was antifreeze coming out the wheel well. This spring when I decided to
repair/replace ALL of it, also discovered the actual switch (top switch, bottom outlet) was bad also - which probably is why the element burnt up and
started advanced corrosion to start with.

Short answer - put eyes and meters on actual components and verify both soundness and functionality, especially before you drink it.

Maybe see if the engine loop heats the tank, you may have hot water and the house system is not delivering it.

The breakers all appear to be on, I did a continuity test an the is
continuity, even tried run the unit on the generator and no luck thus far.

Use your VOM and Chevy the voltage across the two terminals on the heating element. Then shut off the switch, disconnect one wire from the heating element and check the ohms across the two terminals of the heating element. Let us know what you find.

Should have read "check" not Chevy.

Bill,

Something is wrong, you should not get continuity when you check the heater element.

IIRC the element is 1500 Watts divided by 120 Volts equals 12.5 Ohms.

Rob M.

There is often a reset switch on the thermostat mounted to the water heater.

Bill
What year and model GMC do you have?

Is the water heater electric as in the models GMC built or do you have a Royale or other model built on a chassis from GMC?

Is the water heater all electric or modes it have a propane burner?

Minor course correction here. The voltage across the element is not dependent on the condition of the element, only on the circuit from the power
source being unbroken. The element can be burned out and still read 120VAC when power is applied to it. With the power disconnected, it will be an
open circuit (or at least very high resistance) using an ohmmeter if the element is burned out.

Verify that 120V is getting to it, and if it still does not heat, it is definitely burned out.

Rob,

We don't what he checked continuity with....
If it was a "Free at Hazard Fright" VOM, it may look like continuity as opposed to open.

A few questions:

1. Do you have water flowing from both hot and cold faucets ?

2. Do you have power at wall outlets ?

3. Have you tried with generator power ?

4. Is there a by-pass kit installed on the water heater for winterization ?

The GMC Motorhome uses a 240V plug that splits into two circuits. Normally the water heater will operate when using an adapter to a 15AMP plug , but
I have experienced adapters that power the Air Conditioning circuit.

If you are experienced working with AC Power, use your volt meter to check to make sure the heater is getting power. If not, you have a problem in the
AC wiring.

If you are getting power to the heater the problem is either the thermostat ( on the heater), the element, or the wiring in the heater. Use your volt
meter to determine.

Good Luck ! Let us now what you find.
