    Common Issues with Tankless Water Heaters

    Tankless water heaters are a modern and efficient alternative to traditional water heaters with storage tanks. However, like any complex appliance, tankless water heaters can encounter issues that may disrupt their performance.

    Let’s explore some common problems that may necessitate tankless water heater repair:

    No Hot Water: Causes and Solutions

    One of the most frustrating problems you may encounter with a tankless water heater is the absence of hot water when you need it most. This issue can be caused by faulty heating elements, a malfunctioning thermostat, or gas supply issues for gas-powered units.

    Our expert technicians will diagnose the root cause and provide swift and effective solutions to restore your hot water supply.

    Insufficient Hot Water: Identifying the Culprits and Resolving the Problem

    If you find yourself running out of hot water too quickly or experiencing lukewarm showers, your tankless water heater may be facing insufficient hot water production.

    This could be due to undersized units for your household’s demand, mineral buildup in the heat exchanger, or other factors.

    Our team will assess your specific needs and recommend appropriate repairs or replacements to ensure your tankless water heater meets your hot water demands.

    Fluctuating Water Temperature: Understanding the Triggers and Necessary Repairs

    Fluctuating water temperature during showers can be an unsettling experience. This issue could be caused by a malfunctioning flow sensor, gas pressure irregularities, or problems with the heating element.

    Our skilled technicians will perform thorough troubleshooting to pinpoint the issue and implement the necessary repairs to stabilize your water temperature.

    Leaking Water: Detecting and Addressing Leaks for Preventive Maintenance

    Leaking water around your tankless water heater is a cause for concern as it can lead to water damage and potential system shutdown. Leaks can occur in the connections, valves, or pipes, and prompt action is essential to prevent further damage.

    Our experts will locate and repair the leaks, ensuring your tankless water heater functions optimally and avoiding unnecessary water wastage.

    Error Codes or Warning Lights: Decoding and Troubleshooting for Effective Repairs

    Modern tankless water heaters are equipped with sophisticated control systems that display error codes or warning lights to indicate specific issues.

    Our technicians are well-versed in deciphering these codes, enabling them to perform accurate diagnostics and implement timely repairs to resolve the underlying problems.

    Ignition Failure (Gas Models): Investigating the Root Cause and Professional Solutions

    Gas-powered tankless water heaters rely on ignition processes to heat water. If your unit experiences ignition failure, it could result from issues with the gas supply, igniter, or combustion chamber.

    Our team has the expertise to investigate the root cause and provide reliable repairs to ensure safe and efficient operation.

    Mineral Buildup (Scaling): The Impact of Hard Water and Scaling Remediation

    The presence of hard water can lead to mineral buildup, also known as scaling, in the heat exchanger of your tankless water heater. Scaling reduces the unit’s efficiency and may even lead to irreparable damage if left unattended.

    Our team can address scaling issues through descaling methods or recommend water softening solutions to protect your tankless water heater and extend its lifespan.

    The Importance of Professional Tankless Water Heater Repair in Hawaii

    Your Plumbing & AC Dream Team

    Audie was the representative from Steves Plumbing that came to our house. He was very professional and had a warm friendly demeanor. Audie was able to quickly diagnose the problem. He took his time to explain the situation, what needed to be done with our shower valve and explained everything in a way that we can easily understand it. He also noticed the brands on our fixtures in our bathroom (toilet, sink) and gave recommendations on what he believed would be more durable. We believed this is going above and beyond his duty. If we ever have any plumbing needs in the future, we will definitely call Steves Plumbing and specifically ask for Audie.

    One of the best plumbing experiences I’ve ever had. Prompt service. Very knowledgeable tech. Kaalai was super nice and repaired our leak in a professional manner. I would recommend Steve’s Plumbing to all my friends and neighbors.

    – Hunt D.

    We have been a customer for almost 20 years. They do good, professional work with aloha. Response time has always been excellent. Today I broke a water pipe and they responded immediately. They sent VICTOR, who we HIGHLY RECOMMEND! WE WILL ALWAYS USE STEVE’S PLUMBING!

    – Diana M.

    I called Steve’s Plumbing on a Sunday morning and the service guy was here before noon without charging extra for Sunday! Billy fixed my clogged sink and spent over 3 hours clearing the clog that was way down the pipe. He was professional and explained everything to me. The price was reasonable considering all the work he did. I was very happy with the results.

    – Susie C.

    Victor overhauled our main property water shut off the box. A lot of corroded handles/valves that were not an easy DIY project. The office gave courtesy calls before he arrived on time. He was very patient in answering all of my many questions and concerns. Explained options to me & also introduced me to the “Ohana Membership” (be sure to get it). Upon completion, he was very thorough in showing me “what did what”. No more confusion or concerns. He even took time to answer other questions I had about a different “project”. He really takes pride in his work & it shows. Mahalo!
