Furrion tankless water heaters are popular in RVs for on-demand hot water and compact design. When the unit encounters an error or performance hiccup, locating and using the reset button can resolve common issues and minimize downtime. This guide explains where to find the reset button, how to perform a safe reset, and what steps to take if problems persist. It also covers common error codes and preventive practices to maintain reliable hot water on the road.

Identify The Model And Reset Button Location

Furrion offers several tankless water heater models, and the reset button location may vary slightly by model and generation. In most units, the reset button is a recessed switch or a small push button on the front panel or control board access area. Before attempting a reset, confirm you have the correct model and consult the user manual to locate the exact reset point.

Helpful tip: If the front panel is difficult to access, refer to your model’s diagram or the quick-start guide. Some models hide the reset button behind a service panel door, requiring a screwdriver to remove a cover.

When To Use The Reset Button

The reset button is designed to recover from minor faults that cause the heater to shut down or enter a fault state. Use the reset button after:

An error message is displayed on the control panel
The unit refuses to ignite or provide hot water
Unusual operation such as cycling on and off rapidly
Low flame or improper burner operation in gas models

Do not use the reset as a routine reboot if no fault is indicated. Repeated resets without addressing root causes can mask underlying issues and may lead to component wear.

How To Perform A Safe Reset

Follow these steps to reset a Furrion tankless water heater safely. The process is typically quick and requires basic precautions. Always ensure proper ventilation when operating gas models and switch off power if instructed by the manual.

Turn Off Power: If the unit is connected to shore power or a generator, switch it off to prevent electrical shock during access.
Open Access Panel: Remove the service panel or door to reach the reset button, following the manual’s guidance.
Identify The Reset Button: Locate the recessed or small push-button reset switch on the control board.
Press And Hold: Press and hold the reset button for 3–5 seconds, then release. Some models require a brief press, others a longer hold; follow the manual precisely.
Turn Power Back On: Restore power and observe the display. If the unit powers up normally, it may resume normal operation.
Test Hot Water: Run a hot water tap to confirm proper heating. If the flame or burner does not ignite, proceed to troubleshooting.

If the display still shows an error code or hot water is not produced after reset, do not repeat the reset multiple times in quick succession. Move to targeted troubleshooting to identify the underlying cause.

Interpreting Common Error Codes

Furrion’s tankless models use fault codes to indicate the issue. Understanding the codes helps diagnose problems without excessive troubleshooting. Common categories include ignition failures, flame sensor faults, water flow issues, and airflow or venting problems. Always consult the specific error code chart for your model, as codes can vary between generations.

Ignition/Ignition Timeout: Check gas supply, regulator settings, and ignition electrodes for cleanliness and proper alignment.
Flame Sensor Error: Inspect the flame sensor for buildup or misalignment; clean gently with a soft brush if recommended by the manual.
Water Flow Low: Ensure supply lines are open, filters are clean, and there are no kinks in hoses.
Vent/Exhaust Issue: Verify venting is unobstructed with proper clearance and no leaks or restrictions.

Document the exact error code and symptoms. This information helps when contacting support or searching for model-specific guidance.

Advanced Troubleshooting After Reset

If a simple reset does not resolve the issue, proceed with targeted diagnostics. Use the following steps as a structured approach to identify and fix common faults.

Check Power And Battery Connections: Ensure the RV’s electrical system provides stable 12V or required input. Inspect battery connections for corrosion or looseness.
Inspect Gas Supply (Gas Models): Confirm propane supply is uninterrupted, regulator is functioning, and propane lines are free of leaks. Do not test for leaks with an open flame; use soapy water instead.
Clean Burners And Heat Exchangers: Carbon buildup can affect ignition and efficiency. Follow the manual’s recommended cleaning procedure using non-abrasive tools.
Thermal And Flow Sensors: Verify sensors are clean and seated correctly. Replace if damaged or out of tolerance according to the parts list.
Ventilation Check: Ensure the vent system is clear of obstructions, with proper slope and no partial blockages that could trigger safety shutoffs.

Document any component replacements or service actions performed. Keeping a maintenance log helps future diagnostics and resale value.

When To Seek Professional Help

Some problems require trained technicians. If the reset button fails to restore hot water after multiple attempts, or if error codes persist after following the troubleshooting steps, contact a qualified RV technician or Furrion support. Do not attempt extensive disassembly beyond the user-accessible components, as this can void warranties or create safety hazards.

Prepare for service by noting:

Model name and serial number
Exact error codes and symptoms
Recent maintenance or component replacements
Gas supply status and electrical system condition

Maintenance To Reduce Future Reset Needs

Regular preventive maintenance can minimize resets and extend the life of a Furrion tankless water heater. Consider these best practices:

Schedule annual inspections by a certified RV technician
Replace filters and clean water lines per the manual
Inspect venting for corrosion, leaks, and blockages
Keep a tidy control panel area to prevent accidental interference with settings
Avoid running hot water with blocked or restricted outlets, which can trigger fault codes

Proactive maintenance enhances reliability and reduces unexpected shutdowns during trips.

Frequently Asked Questions

Can I reset a Furrion tankless water heater without power? Some functions require power; check the manual for any standalone diagnostics.
Is a reset equivalent to a firmware update? No, a reset clears fault states; firmware updates require official instructions and may be performed by technicians or via official tools.
What if the reset button is not accessible? Refer to the manual for alternate reset methods or contact support for safe service access.
