Signs Your Tankless Water Heater is in Need of Expert Repair

If you are experiencing any of the following issues with regard to your Tankless Water Heater, make sure to call Rock Plumbing, Heating, & Air Conditioning for Expert Tankless Water Heater Repair as soon as possible:

Zero Hot Water

Perhaps the most obvious and concerning sign and symptom of a broken Tankless Water Heater is having no hot water in your Castle Rock house! Any time you simply cannot get any hot water out of your faucets, showers, or other hot-water-using appliances, unfortunately, your instincts are probably correct – Call Rock Plumbing, Heating, & Air Conditioning right away to have a certified plumber inspect your Tankless Water Heater, diagnose the issue, provide a solution, and repair your water heater.

Multiple Appliance Issues

Oftentimes, when a Tankless Water Heater is experiencing issues that require professional repair from Rock Plumbing, Heating, & Air Conditioning, it will then affect other water-using appliances around your Castle Rock home. If you’ve noticed issues with hot water in regards to your washing machine or dishwasher, it’s time to call the pros at Rock Plumbing, Heating, & Air Conditioning to schedule an Expert Tankless Water Heater Repair.

Power Issues

Is your Tankless Water Heater shutting itself off? This is a problem! Power issues with your Tankless Water Issues are usually an indication of a clogged filter. Tankless Water Heaters create extremely hot exhaust, and if your unit is not properly ventilated for whatever reason, it will cause your system to break down and shut down. In the event of power issues within your Tankless Water Heater, call Rock Plumbing, Heating, & Air Conditioning right away to avoid potential fire hazards with your water heater.

Discolored and Foul-Tasting Water

Any time that your water supply is discolored and tinted with a brown, red, yellow, black hue and/or has a foul, metallic-tasting smell to it, something is wrong. Since Tankless Water Heater units do not have a reservoir bank for sediment to form in, you shouldn’t have discolored or foul tasting water, so in the event that you do, call Rock Plumbing, Heating, & Air Conditioning right away! One of our plumbing experts will examine your water heater and water supply to pinpoint the issue and provide repair solutions. It should be noted that water discoloration and foul-tasting water can be caused by many other things in your Castle Rock home, but if you notice it in conjunction with any of our other listed signs of a Tankless Water Heater in need of repair, it’s likely due to your water heater.

Odd Noises

Your Tankless Water Heater system will likely make very faint noises in its normal operation, but if you notice any odd, loud noises such as banging, humming, screeching, or knocking, there is something wrong with your water heater! Make sure to call Rock Plumbing, Heating, & Air Conditioning right away if you hear any loud and unfamiliar noises coming from your Tankless Water Heater to schedule an Expert Tankless Water Heater Repair as soon as you possibly can.

Leaking Water

Tankless Water Heaters should never leak water, so if you are noticing water leaking from your unit, call Rock Plumbing, Heating, & Air Conditioning immediately! It could be due to a loose valve or fitting, or something much more complex, but professional assistance from Rock Plumbing, Heating, & Air Conditioning will be needed.

Frequently Asked Questions About Tankless Water Heater Repair

How Much Does It Cost to Fix a Tankless Water Heater?

It typically costs $150 to $800, though the average tends to be around $600 to fix a tankless water heater. Tankless water heaters require periodic flushing of minerals and sediment from building up inside the unit, and when this maintenance is neglected, you will likely run into issues with your water heater that will need to be repaired by a professional plumber.

Can Tankless Water Heaters Be Repaired?

While tankless water heaters require significantly fewer repairs than storage tank water heaters, they can still encounter problems that will require a professional’s skillset to repair them when those issues do arise.

Why Would a Tankless Water Heater Stop Working?

Your tankless water heater could stop working for a plethora of reasons: a plugged heat exchanger due to hard water, a blocked vent and air intake, or running too many hot water appliances at once. Tankless water heaters only heat water as needed, so running multiple appliances that require hot water can overwhelm your water heater and cause it to stop working. If your tankless water heater stops working, call Rock Plumbing, Heating, & Air Conditioning to have an expert help resolve the problem.

What Are Common Issues With Tankless Water Heaters?

Common issues with tankless water heaters range from air supply and exhaust getting blocked (which can cause the device to shut down), the pilot light failing to ignite, sensors quitting at random, and more. It’s important to have one of our certified technicians at Rock Plumbing, Heating, & Air Conditioning to repair your tankless water heater, as trying to do it yourself could potentially void the warranty or cause further damage.

Why Is My Tankless Water Heater Leaking?

Tankless water heaters do rely on gaskets, seals, and other components that can wear out over time. Generally, an annual maintenance service will include an inspection of these components and give the ability to have them replaced when they start to show signs of wear or failure. However, if you do find water leaking from your system, don’t be alarmed. Simply call a repair technician to come out and take a look at the issue and our team will quickly identify the issue and fix it for you.
