What is Rinnai Error Code 17?

Rinnai error code 17 is a common error that occurs in Rinnai water heaters. This error code indicates that there is a problem with the water flow sensor.

Causes of Rinnai Error Code 17

There are several reasons why Rinnai error code 17 may occur. Some of the most common causes include:

• Dirty or clogged water filter
• Low water pressure
• Blocked water inlet or outlet
• Defective water flow sensor

How to Fix Rinnai Error Code 17

If you encounter Rinnai error code 17, there are several steps you can take to fix the problem. Here are the steps you should follow:

Step 1: Turn off the Power

The first step in fixing Rinnai error code 17 is to turn off the power to the water heater. You can do this by turning off the circuit breaker that supplies power to the heater.

Step 2: Check the Water Filter

The next step is to check the water filter. If the water filter is dirty or clogged, it can cause low water pressure, which can trigger error code 17. To check the water filter, follow these steps:

1. Locate the water filter on the water inlet pipe.
2. Remove the filter from the pipe.
3. Inspect the filter for dirt or debris.
4. If the filter is dirty, clean it with water and a soft brush.
5. Reinstall the filter and turn on the water supply.

Step 3: Check the Water Pressure

If the water filter is clean, the next step is to check the water pressure. Low water pressure can cause error code 17. To check the water pressure, follow these steps:

1. Locate the water pressure gauge on the water inlet pipe.
2. Check the gauge to see if the water pressure is within the recommended range.
3. If the water pressure is low, adjust the pressure regulator to increase the pressure.
4. Turn on the water supply and check if the error code has been resolved.

Step 4: Check the Water Inlet and Outlet

If the water filter and pressure are both okay, the next step is to check the water inlet and outlet. Blocked water inlet or outlet can cause error code 17. To check the water inlet and outlet, follow these steps:

1. Locate the water inlet and outlet pipes on the water heater.
2. Inspect the pipes for any blockages or obstructions.
3. If there are any blockages, remove them using a soft brush or compressed air.
4. Turn on the water supply and check if the error code has been resolved.

Step 5: Replace the Water Flow Sensor

If none of the above steps resolve the error code, the water flow sensor may be defective and needs to be replaced. To replace the water flow sensor, follow these steps:

1. Turn off the power to the water heater.
2. Locate the water flow sensor on the water inlet pipe.
3. Disconnect the sensor from the pipe.
4. Install the new sensor and reconnect it to the pipe.
5. Turn on the power to the water heater and check if the error code has been resolved.
