Noritz Error Code 90- How to fix?

Whether you’re a homeowner or a professional plumber, dealing with a troubled water heater like the trusted units manufactured by Noritz can be quite the headache. One of the common problems they face is the notorious Noritz error code 90. This is a technical disruption hampering your unit’s performance, leaving you with cold water when you need it hot. Often, homeowners find themselves hunting for solutions.

What is the Noritz Error Code 90?

Noritz Error Code 90 is a common fault code referring to a combustion abnormality. In layman’s terms, this simply means there’s a problem with the burning of gas inside your water heater, which invariably stops the heating process. This problem can potentially be caused by a number of factors such as inadequate gas supply, improper venting, or even blockages in your unit’s fan motor.

How to Fix the Noritz Error Code 90?

Before tinkering around with your unit, it’s best to understand the basics of the resolving process. When the Noritz error code 90 flashes on your screen, the first step you always need to take is shutting down your unit completely. Safety first!

Next, we advise homeowners to inspect the gas supply. Inadequate gas supply is a common cause for this error. Ensuring your gas supply is neither too high nor too low is key. In case you’re unsure, it’s best to call a professional to inspect your gas supply.

The Role of Proper Venting

After confirming your gas supply is in good order, the next thing to look into is your unit’s venting. Improper venting might cause the Noritz error code 90 because misuse can lead your unit to overheat or even fail. The unit’s fan, which plays a vital role in venting, should be free of obstructions. Whether it’s dust, debris or even bird nests, make certain nothing is blocking the flow.

Professional Inspection of the Fan Motor

If the first two steps haven’t fixed the problem, it’s time to consider other possibilities. Your unit’s fan motor could be malfunctioning due to wear and tear, or it could be a manufacturing defect. At this point, it’s crucial to note that attempting to inspect and fix the fan motor yourself is not recommended, as it may lead to a void in your unit’s warranty or even cause further damage.

Noritz Error Code 90: The Bigger Picture

While doing your best to inspect and troubleshoot, it’s important to realize that the Noritz Error Code 90 may also be indicative of larger issues. If you’re constantly dealing with this problem, even after attempting fixes, it might be time to call in a professional technician for a comprehensive diagnosis of your unit. Professional diagnostics typically analyze aspects that may be overlooked, and they can often provide long-term solutions.

With this guide on hand, encountering the Noritz Error Code 90 should be a little less daunting. While the tips above may serve as preliminary attempts to resolve the issue, it’s crucial to remember that a professional hand is always vital in these matters. Stay proactive, aware, and intentions focused on safety—a warm, relaxing bath may just be a manageable fix away.
