assuming you needed the main HW switch on when using the HW heater.
If I understood your comments correctly all I need to do is to turned on the elec switch located on the HW heater and not the Water Heater switch on the main switch panel if I only want to run on elec. I understand the reasons to have both on.
Would be helpful if this info was included in the operation manual....but then again we won't have this FORUM.
Thanks for the quick response.
You are correct. The switch inside your RV is ONLY to the propane/dsi side of your water heater. This is the switch you use to turn on the Direct Spark Ignitor for your propane. Only use it when you are wanting to use the propane part of your water heater.
The switch, accessed from outside your RV, on the front of the water heater is ONLY to the electric heating element.
If you only want to use the electric heating element, then you turn on the outside switch (make sure there is always water in the heater though beforehand). You will leave the switch inside your RV, in the OFF position.
Don't feel bad, this is one of the most misunderstood things, and is very ill-explained by many RV dealers when purchasing a RV. This is why we have the detailed FAQ I linked you to here in the forum. Hope it helped.
So, if I am correct in my initial assumption..you did have the inside DSI switch on, but the water heater wasn't using propane because the propane tanks were off. Here is another tidbit. Since the propane tanks were off, the DSI wouldn't have been able to ignite the propane (cause there wasn't any). This is also what shows up as a fault in the system. If you will look at the pic you posted of the inside switch, you should also see the little red light beside it that says DSI Fault. This light should have been on the whole time that the switch was on, yet the propane wasn't. it's an indicator for you. Also this light will come on when you first turn on the switch, until the DSI ignites the propane, which can take a few seconds, usually 15-30. After the propane ignites, the red fault light goes off. If it doesn't then the propane isn't lighting and you need to check and find out why.
This is also explained in the FAQ link.
