Suburban RV Water Heater Accessories

How do I find the right replacement part for my Suburban RV water heater?

Start with the model and serial tag on your water heater, usually mounted on the inside of the access door. Suburban models are coded by series (SW = Suburban Water Heater, the number = gallon capacity, D = DSI ignition, E = electric element, etc.), so an SW6DE is a 6-gallon DSI unit with an electric element. Match that model number against the parts diagram for your unit before ordering. If you need help confirming fitment for a part like the 232881-002 control board or an IW60 flow sensor (233237), text or call our team at 817-984-1852.

Do you carry parts for the Suburban ST-60 and IW60 water heaters?

Yes. This collection covers 63 accessories and replacement components for Suburban gas, electric, and DSI water heaters, including the ST-60 series and IW60 tankless units. Common parts in stock include the IW60 water flow sensor (233237), control boards, gas valves, thermostats, thermal cutoffs, anode rods, drain plugs, and door assemblies. If your Suburban tank uses a magnesium or aluminum anode rod, you can also check our 10 gallon RV water heater collection for compatible tank-protection hardware.

Where can I find a Suburban 6 gallon RV water heater parts diagram?

Suburban publishes exploded parts diagrams in the service manual for each model series (SW6D, SW6DE, SW6DEM, etc.). Most 6-gallon units share the same burner assembly, gas valve, and tank hardware, with differences mainly in the ignition control board and electric element wiring. We recommend pulling the diagram for your exact model number rather than relying on a generic 6-gallon view, then cross-referencing the OEM part number (for example 161,292 / 667003) against the listings in this collection.

What other RV systems should I service alongside the water heater?

If you are pulling the water heater for parts replacement, it is a good time to inspect adjacent systems. Drain and flush the tank, check the anode rod, and test the pressure relief valve. Owners in cold climates should also review their RV winterizing kits to protect the tank and lines during storage, and 120V components like the electric element relay can be tested while you have access to your RV electronics panel.
