Heat Pump Water Heater Maintenance: Complete Rheem Care Guide & Troubleshooting

Keeping up with heat pump water heater maintenance is one of the best ways to make sure your system runs efficiently, safely, and lasts as long as possible. If you have a Rheem model, a little routine care can go a long way. In this guide, we’ll walk you through the basics of Rheem heat pump maintenance, how to troubleshoot common heat pump water heater issues, and when it’s time to call in a pro. 

How Do You Maintain a Heat Pump Water Heater? 

Keeping your heat pump water heater running efficiently doesn’t take much. A consistent maintenance routine is a simple way to help extend the life of your system and avoid unnecessary repairs. 

Start by checking the air filter each month. Dust buildup can affect performance, so regular heat pump air filter cleaning with mild soap and water keeps airflow strong. While you’re at it, inspect the condensate drain to make sure it’s clear, and do a quick visual check for any leaks, corrosion, or wear. If your unit is connected to the EcoNet^® App, check for any alerts or spikes in energy usage. Every few months, make sure there’s at least 18 to 24 inches of clearance around the unit for proper airflow. Verify the water temperature settings and listen for any unusual sounds during operation, as strange noises could signal a problem. 

As part of your annual heat pump service, it’s best practice to schedule a visit from a Rheem-certified plumber. They’ll handle tasks like flushing the tank to remove sediment, testing the temperature and pressure relief valve, and inspecting electrical connections—things best left to a pro for safety and performance. If you have a Rheem^® ProTerra^® model, follow a maintenance schedule by updating and calibrating the EcoNet software annually. It’s also a good idea to test hybrid mode and review yearly energy usage through the app to track long-term system performance. With just a bit of regular care, your heat pump water heater will keep running efficiently for years to come. 

What Are Common Heat Pump Water Heater Problems and Solutions? 

While heat pump water heaters are generally reliable, you may occasionally run into issues. Fortunately, most common heat pump water heater problems are easy to identify and fix. 

If your heat pump water heater is not heating, start by checking the power supply and circuit breaker. Make sure the thermostat is set between 120°F and 140°F and that the unit is in the correct mode (Auto, Heat Pump, or Electric). The EcoNet app can also alert you to any errors or required maintenance. 

For weak or inconsistent hot water, a clogged air filter is often the cause. Regular heat pump air filter cleaning helps maintain proper airflow. Also, ensure the space around the unit stays between 40–90°F, and consider flushing the tank if sediment buildup is suspected. If demand is high, adjusting usage or scheduling through the app can help. 

Unusual noises can flag different issues: gurgling often signals sediment buildup, while persistent clicking or banging may require inspection. Fan noise might indicate debris in the air intake. Frequent cycling could mean the unit is undersized or overworked. If performance drops, revisit the basics: clean the air filter, confirm there’s proper clearance, and check for extreme temperatures. Error codes can be found in the EcoNet app or owner’s manual, and poor recovery time may point to high simultaneous water usage. Water quality issues, like discoloration or metallic taste, may require an anode rod replacement. Leaks can come from valves or pipe connections, while excess condensation might signal a drain issue. 

If you’re unsure, troubleshooting Rheem ProTerra systems is easier with a quick call to your local Rheem pro. 

When Should You Call a Rheem Professional for Service? 

While some basic professional heat pump maintenance tasks like filter cleaning and visual inspections can be handled by homeowners, there are times when calling in a pro is the smart move. 

Electrical work, anything involving the refrigerant system, or replacing internal components should always be left to the experts. The EcoNet app can also let you know when to call a technician, especially if you’re seeing persistent error codes that don’t clear with standard troubleshooting. 

There are a few clear signs that require professional attention: recurring error codes, possible refrigerant leaks, compressor issues, or any electrical problems like tripping breakers or a burnt smell. Internal water leaks or major plumbing connection failures also warrant a service call. Choosing Rheem-certified service comes with real benefits. Certified plumbers are trained specifically on ProTerra systems, have access to genuine Rheem parts, and know how to properly calibrate smart features. Plus, having a professional handle service helps protect your warranty. During an annual inspection, a certified tech will perform a full system check, complete tasks beyond what most homeowners can do, optimize performance settings, and maintain records for warranty compliance.
