  • Descale the heat exchanger to remove mineral buildup.

Causes: Clogged filters, incorrect pressure settings, or water flow restrictions.

  1. Inspect and clean filters regularly.
  2. Adjust pressure settings as per manufacturer’s guidelines.
  3. Check for any obstructions in the water lines.

Causes: Inconsistent flow rate, thermostat issues, or inlet water temperature fluctuations.

  • Ensure a steady water flow for stable temperature.
  • Calibrate the thermostat settings accurately.
  • Check and adjust the inlet water temperature for consistency.

No Hot Water

No Hot Water: If your Furrion tankless water heater is not producing hot water, you may need to perform some troubleshooting steps to identify and resolve the issue.

Check Gas Supply

Ensure the gas supply to the water heater is connected and turned on properly.

Check for any gas leaks or obstructions that may be affecting the flow.

Inspect Water Flow

Check the water flow rate entering the heater and ensure it meets the minimum requirements.

Remove any debris or mineral buildup that may be blocking the water flow.

Low Water Pressure

Low water pressure in your tankless water heater can be frustrating, leading to inadequate flow and diminished performance. Troubleshooting low water pressure can solve this issue effectively. Below are some common troubleshooting steps to resolve low water pressure in your Furrion tankless water heater.

Clean Filter Screen

The first step in troubleshooting low water pressure is to clean the filter screen. Over time, debris and sediment can build up in the filter screen, inhibiting water flow. To clean the filter screen, follow these steps:

  1. Turn off the water supply to the heater.
  2. Locate the filter screen on the water inlet side of the heater.
  3. Remove the screen and clean it thoroughly, removing any accumulated debris.
  4. Reinstall the filter screen and turn the water supply back on.

Adjust Water Flow

If cleaning the filter screen does not resolve the low water pressure issue, you can try adjusting the water flow. Follow these steps to adjust the water flow in your Furrion tankless water heater:

  1. Check the water flow settings on the heater to ensure they are adjusted correctly.
  2. If necessary, adjust the water flow settings according to the manufacturer’s instructions to optimize water pressure.
  3. After making the adjustments, test the water pressure to ensure the issue has been resolved.

Fluctuating Temperature

If you’re experiencing fluctuating temperatures from your Furrion tankless water heater, you’re not alone. This common issue can be frustrating, especially when you’re trying to enjoy a consistent supply of hot water. However, there are a few troubleshooting steps you can take to address this problem and ensure your water heater is functioning optimally.

Check For Air Bubbles

Air bubbles can sometimes get trapped in the water lines, causing fluctuations in temperature. To check for air bubbles, follow these steps:

  1. Turn off the power supply to the water heater.
  2. Locate the water shut-off valve and close it.
  3. Find the faucet closest to the water heater and open it.
  4. Let the water run for a few minutes to help release any trapped air bubbles.
  5. Close the faucet and open the shut-off valve.
  6. Restore power to the water heater.

By eliminating any air bubbles in the system, you can improve the water flow and reduce temperature fluctuations.

Adjust Temperature Settings

Another possible cause of fluctuating temperatures is incorrect temperature settings. To ensure your Furrion tankless water heater is set to the desired temperature, follow these steps:

  1. Locate the temperature control panel on your water heater.
  2. Press the “Temperature” button to access the temperature settings.
  3. Use the up and down arrow buttons to adjust the temperature to the desired level.
  4. Press the “Set” button to save the new temperature setting.

By properly adjusting the temperature settings, you can maintain a consistent supply of hot water throughout your home.

By following these troubleshooting steps, you can effectively address the issue of fluctuating temperatures from your Furrion tankless water heater. If the problem persists, it may be necessary to contact a professional technician who can further diagnose and resolve any underlying issues.

Maintenance Tips

Maintaining your Furrion tankless water heater is essential to ensure its optimal performance and longevity. Regular maintenance can help you avoid common issues and troubleshoot any problems that may arise. Here are some maintenance tips to keep your tankless water heater running smoothly:

Regular Descaling

Over time, mineral deposits can build up inside your tankless water heater, affecting its efficiency. Regular descaling is necessary to remove these deposits and maintain the flow of hot water. Follow the manufacturer’s instructions on how to descale your specific model. In general, the process involves flushing the system with a descaling solution or vinegar to dissolve the mineral buildup.

Clean Water Inlet Filter

The water inlet filter in your tankless water heater helps prevent debris and sediments from entering the unit. A clogged or dirty filter can restrict water flow and impact the performance of your heater. Regularly check the water inlet filter and clean or replace it as needed.

Inspect Venting System

The venting system is crucial for the proper operation of your tankless water heater. It removes the combustion gases from the unit. Inspect the venting system regularly to ensure there are no blockages or obstructions that could inhibit the flow of gases. Clear any debris or buildup in the venting system to maintain optimal airflow.

Check For Leaks

Periodically inspect your tankless water heater for any signs of leaks. Check the connections and fittings for any visible water seepage. If you notice a leak, tighten the connections or replace any faulty components to prevent further damage. Ignoring leaks can lead to more significant issues down the line.

Keep The Unit Clean

Keeping your tankless water heater clean is essential for its efficient operation. Dust, dirt, and debris can accumulate on the unit over time, hindering its performance. Regularly wipe down the exterior of the heater using a soft cloth to remove any dirt or dust particles. Additionally, ensure the area around the heater is free from clutter or obstructions.

By following these maintenance tips, you can keep your Furrion tankless water heater in excellent working condition and avoid any potential issues. Regular descaling, cleaning the water inlet filter, inspecting the venting system, checking for leaks, and keeping the unit clean are simple steps that can go a long way in maintaining the performance and longevity of your tankless water heater.
