What Does DSI FLT Mean on My Camper?
When RVing, hot water is essential. However, sometimes the hot water may fail us when needed most. And you even get a code that will not be available at the time DSI FLT. Interpreting the meaning of the code is a real task.
The dsi flt light
The initials would mean direct spark ignition and fault respectively. Basically, it is the device that works to add the flame to the gas so your water can be heated. Normally during operation, the dsi flt light turns on when you try turning on the propane switch of the water heater.
It indicates that igniting the burner of the heater was unsuccessful. In other words, the fault code shows that no propane gas is coming through the line to heat your water. However, if the water fires up correctly, the light goes out.
The fault code could also mean something else. To troubleshoot the issue, you need to check on the propane supply. If that is okay, the next place to check is the burn chamber as it could be clogged with carbon flakes that need cleaning out.
If the heater is not running in gas mode, another possible culprit would be the energy cut-off (ECO) switch. If activated, it stops the unit, preventing overheating of the water. The thermostat could also be faulty.
What Is the History of Dsi?
The DSI system was invented by the Fenwal Company. Before that, the heaters were manually turned on by lighting the pilot light outside the RV.
What Are the Benefits of the DSI System?
The DSI is considered one of the safer systems that can be used in an RV. It is also convenient and makes work easier. Traditionally, one had to leave their RV and go to the ignition and light the pilot light manually. This was a dangerous trade since, if the pilot light did not stay lit, propane would be pumping into the RV and cause life-threatening risks.
Thankfully, the DSI eliminates that danger as it serves to automatically light the gas once turned on. Moreover, if any danger is detected, the DSI shuts off the gas flow.
Typically, it is designed to attempt to light the gas three times, and if all attempts are unsuccessful, it locks the gas supply. Also, if the set temperature has been reached, the control board turns off the ignition. The pilot light would stay on until you manually turn off the gas supply.
How to Reset the RV Water Heater
Thankfully, the fault code is no cause for alarm. You can quickly and easily reset the heater. That is made easier with the technology that these heaters use, which includes a reset button. This way, it is just a matter of pushing the button so the water heater comes back to working order.
However, locating the reset button is no easy feat for many. The heaters come in different designs. For the gas and electric combination water heaters, their reset button is likely to be located on the WH panel usually outside the RV. The position of the button varies depending on the RV’s model.
The reset button works to reset the 12V electrical component and fire it up again. For the combination water heaters, there are two reset buttons. The one on right resets the electrical side of the operation.
Thankfully, there is always an owners’ manual that highlights all that you need to know. It shows the location of the buttons complete with diagrams so you can easily find them.
Moreover, you will have to wait for the DSI’s three attempts before you reset the heater. There is usually a clicking noise for every attempt.
However, if this reset works temporarily, the problem may lie somewhere else. It could mean some parts are malfunctioning and need replacement or repair.
DSI Fault Reset
DSI water heaters are of different types. The most popular one is the on-demand unit due to its economic savings and efficiency. For the RVs with this system, the DSI code may appear sometimes, and if it does, you need to reset it.
There are different methods of resetting it. First, you may have to turn off all the power going to the trailer for 15 minutes, and then re-establish a connection. The second method could be to turn off and disconnect the propane tank, after which you reconnect it and slowly turn the opening valve. The final suggestion is to ensure that the heater was hooked onto a 120v supply.
If the reset is not successful with any of the methods, you may have to call a professional to help you out. It is important to note that anytime you are resetting, all the stove burners are turned off.
