If you own a Rheem water heater, boiler, or heat pump, you’ve probably faced a hiccup at some point. The good news? Most problems are easy to spot and fix, or at least diagnose before you call a pro. In this guide we’ll walk through the most common issues, quick checks you can do yourself, and when it’s smarter to call an expert.
Rheem units are built to last, but wear and tear happen. Here are the three faults you’ll see most often:
1. No Hot Water – Start by checking the power supply. If it’s an electric heater, make sure the breaker hasn’t tripped. For gas models, look at the pilot light; a blown out pilot is a quick reset away. If the heater runs but still doesn’t heat, the thermostat could be stuck or the heating element may need replacement.
2. Strange Noises – Rumbling, ticking or squealing usually means sediment buildup in the tank or a loose fan belt in a heat pump. Flushing the tank once a year clears sediment. Tightening or replacing a belt is a simple DIY job if you’re comfortable with basic tools.
3. Leaking Water – Leaks often come from the pressure relief valve or a cracked tank. The relief valve can be tested by gently lifting its lever; if water sprays out, the valve is working. A cracked tank, however, means the unit is at the end of its life and should be swapped out.
DIY can save money, but some situations are better left to trained technicians. If you notice any of these signs, pick up the phone:
• Repeated loss of hot water even after resetting the thermostat.
• Persistent error codes on the display that don’t clear after a power cycle.
• Gas smells or carbon monoxide alarms – shut the unit off and ventilate the area immediately.
• Extensive corrosion or rust on pipes and connections.
Professional Rheem technicians have the right tools, safety certifications and warranty knowledge to fix complex problems without risking further damage.
Regular maintenance cuts down on surprise breakdowns. A yearly check‑up by a certified service person can catch worn parts, check gas pressure, and clean internal components. It’s a small cost that pays off in reliable hot water and heating when you need it most.
Finally, keep your appliance’s model number and serial handy. This info helps the tech order the right parts fast and can speed up any warranty claim. Most Rheem units come with a one‑year parts warranty, and many dealers offer extended plans for peace of mind.
Now you’ve got a solid rundown of what to look for, how to troubleshoot, and when to bring in the pros. Keep this page bookmarked – it’s your quick reference whenever a Rheem unit acts up. And remember, regular care keeps your heater, boiler or heat pump humming smoothly for years to come.
