Turn Off The Water Heater For 5 Minutes.
Stop the water heater supply by closing the main valve. Unplug the water heater to turn it off. Remove the water heater cover and unhook the intake pipe. When shutting off the hot tub, disconnect the gas feed to the water heater and check for leaks.
Remember to reconnect the drains after replacing the water heater panel. Before using the water heater, fill its gas tank and change the steam valve.
Replace Your Water Heater.
Turn off the water heater by pulling the plug and removing the lid. Before recharging the water heater, wait three minutes after turning it off. This is when you can scrape the spark plug.
After the three-minute delay, connect the tubes after setting up the igniter. Upgrading your water heater may be a wise update for efficiency and performance.

Check For Leaks In The Gas Line.
Turn off all electrical devices and turn on the main light to look for gas leaks. Check for any smoke or sparks from the device to ensure no gas leak. Turn off the main switch and contact a professional if you smell gas. A leak in a line can be found using a meter. Stop gas flow into the house and examine the meter line for leaks. If the pipe pressure is too low, there may be a leak. High pressure usually indicates that a line is in good condition. When a line springs a leak, it needs to be replaced.
How To Fix Gas-Related Problem Causing Error Code 17?
- First, ensure your tankless device has a steady gas supply.
- You must also confirm that the gas type matches the rating plate on your tankless unit.
- Simply set the dip switch on the electronic board of your propane tankless unit or any other variant to the correct type.
- Furthermore, the gas pressure must be aligned in accordance with the rating plate.
- There could be several causes for low gas pressure, including the faulty size of the gas system, failure to meet manufacturer specifications, and, most critically, filth and debris.
- After the installation, the air must be purged from the gas lines to avoid any last-minute mishaps.
- If you are unsure about repairing the problem yourself, the best thing you can do is call a licensed specialist who will save you time and keep you from being exposed to dangerous gases, etc.
How To Repair The Igniter Problem Causing Rinnai Error Code 17?
- First and foremost, you must examine the ignitor’s condition.

- Cross-check the correct voltage on the electric board when your tankless unit is in the ignition cycle.
- To position the igniter appropriately, tightly tighten it and its ceramic insulation to the mounting bracket.
- The biggest issue with a Loose Rod is that it can create no sparks or sparks that last for a shorter period if it comes into touch with other metal components.
- If you intend to replace an element, you must replace the gasket.
- To avoid any last-minute mishaps, examine the igniter and clean any carbon or scale accumulation as stated in the handbook.
