Common Issues
One common issue is a lack of power. Check if the control panel is getting electricity. Ensure the circuit breaker is not tripped. A power surge might also cause problems. Inspect the power cord for damage. Replace any faulty cords immediately. Make sure the outlet is working properly. Use a different device to test the outlet. If the outlet is faulty, call an electrician.
Loose or damaged wires can cause the control panel to fail. Inspect all wiring connections carefully. Look for any signs of wear or damage. Tighten any loose connections to ensure a secure fit. Replace any frayed or broken wires. Incorrect wiring can also be a problem. Verify that all wires are connected correctly. Consult the manual for proper wiring instructions.
Initial Troubleshooting
Experiencing a Rinnai tankless water heater control panel malfunction can be frustrating. Start by checking the power supply and circuit breakers. Ensure all connections are secure and inspect for any visible damage.
Check Power Source
Ensure the unit is plugged in. The power cord should be secure. Check the outlet for any damage. Try another device to see if the outlet works. If it doesn’t, there could be a problem with the outlet itself. Use a voltage tester to check for power. No power means the problem is likely with the outlet.
Inspect Circuit Breaker
Find your home’s circuit breaker panel. Check if any breakers are tripped. A tripped breaker means it has switched off to prevent damage. Flip the breaker back to the “on” position. If it trips again, there might be a serious issue. Do not force the breaker to stay on. Call a professional if needed.
Resetting The Control Panel
Find the reset button on the control panel. It is usually small and red. Look near the bottom of the panel. You may need a small tool to press it.
Press and hold the reset button for 5 seconds. Wait until the panel lights up. Release the button after the lights come on. The control panel should now work properly.

Inspecting The Wiring
Loose connections can cause problems. Ensure all connections are tight. Use a screwdriver to tighten any loose screws. Check each wire connection one by one. Make sure they are properly secured. Loose connections can disrupt the system. This can lead to the control panel not working.
Damaged wires are a common issue. Inspect the wires for any cuts or frays. Replace any damaged wires immediately. Damaged wires can cause the control panel to malfunction. Be careful when handling wires to avoid further damage. Ensure no wire is exposed. Exposed wires are dangerous and can cause short circuits.
Replacing The Fuse
First, turn off the power to the heater. Find the control panel on the heater. Open the panel using a screwdriver. Inside, you will see a fuse. It is usually a small, cylindrical part. Check the manual if you cannot locate it. Make sure to handle the fuse with care.
Remove the old fuse carefully. Look at the fuse for its rating. Get a new fuse with the same rating. Insert the new fuse in the same place. Close the control panel and turn the power back on. Check if the control panel is now working.
