Understanding Why Your EcoSmart Isn’t Heating: Key Components and Issues

Before diving into specific fixes, it’s helpful to understand the inner workings of your EcoSmart tankless water heater. This knowledge will empower you to troubleshoot effectively and identify the root cause of the problem.

The Importance of Troubleshooting

Troubleshooting isn’t just about randomly trying solutions. It’s a systematic process of elimination. By understanding how your EcoSmart should work, you can pinpoint what isn’t working correctly. This targeted approach saves time, money, and frustration.

The Heart of the System: The Heating Element

The heating element is arguably the most critical component in a tankless water heater. It’s responsible for rapidly raising the water temperature as it flows through the unit. When you turn on a hot water tap, cold water enters the EcoSmart, and the heating element is activated to heat the water on demand.

If the heating element fails, the water will pass through the unit without being heated. This may occur because the element itself has failed or because it is not receiving power or instructions to activate.

The Gatekeepers: Flow and Temperature Sensors

Two critical sensors play crucial roles in the heating process: the flow sensor and the temperature sensor.

Flow Sensor Functionality

The flow sensor detects when water is flowing through the unit. It acts as a trigger, signaling the system to activate the heating element. If the flow sensor is faulty or obstructed, it may not register water flow, preventing the heating element from turning on, even when a tap is open.

Temperature Sensor Functionality

The temperature sensor monitors the outgoing water temperature. It ensures that the water is heated to the desired level set on your unit’s control panel. If the temperature sensor malfunctions, the heater might not reach the set temperature or may overheat, causing it to shut down. It can also cause the unit to shut down completely, even if the water is cold.

Both sensors work in tandem to ensure optimal and safe operation.

The Silent Saboteur: Sediment Buildup

While less directly related to component failure, sediment buildup is a common culprit behind heating problems in tankless water heaters. Over time, minerals like calcium and magnesium in the water can accumulate on the heating element and other internal components.

This sediment acts as an insulator, reducing the heating element’s efficiency. The unit has to work harder to heat the water, consuming more energy and potentially leading to premature component failure. In severe cases, sediment buildup can completely block water flow, preventing the unit from heating at all. Regular flushing can help prevent this issue.

Troubleshooting Step-by-Step: 5 Common Fixes for a Cold EcoSmart

Now that you understand the key components that make your EcoSmart tankless water heater function, let’s dive into practical solutions. Here are five common fixes you can try to get your hot water flowing again.

Fix 1: Check the Circuit Breaker – The Power Source

A tripped circuit breaker is a surprisingly common culprit behind a non-heating EcoSmart. Tankless water heaters, especially electric models, require significant power to heat water on demand. This high power demand can sometimes overload the circuit, causing the breaker to trip as a safety measure.

How to Check and Reset the Breaker

1. Locate your electrical panel. This is usually in the basement, garage, or utility room.
2. Identify the breaker for your EcoSmart water heater. It should be labeled, but if not, consult your home’s electrical diagram.
3. Check the breaker’s position. A tripped breaker will usually be in the "off" or a middle, loosely defined position.
4. Reset the breaker. First, flip the breaker completely to the "off" position. Then, flip it firmly to the "on" position.

Electrical Safety First

Always exercise caution when working with electricity. If you are unsure about any step, consult a qualified electrician. Never touch any exposed wires or components. Make sure your hands and the surrounding area are dry.

If the breaker trips repeatedly, there may be an underlying electrical issue. This could indicate a short circuit, an overloaded circuit, or a faulty breaker. In such cases, it is essential to consult with a qualified electrician to diagnose and repair the problem. Do not continue resetting the breaker without addressing the root cause.

Fix 2: Flush Out Sediment Buildup – Restore Heating Efficiency

Sediment buildup is a common issue in water heaters, especially in areas with hard water. Over time, minerals like calcium and magnesium can accumulate inside the tankless water heater, forming a layer of sediment on the heating element.

The Insulating Effect of Sediment

This sediment acts as an insulator, preventing the heating element from efficiently transferring heat to the water. As a result, the water may not reach the desired temperature, or the unit may struggle to heat the water at all.

How to Flush Your Tankless Water Heater

Flushing your tankless water heater removes this sediment buildup, restoring its heating efficiency. Here’s a general guide, but always consult your EcoSmart owner’s manual for specific instructions for your model.

1. Gather your supplies: You’ll need two flexible hoses, a submersible pump (optional, but recommended), a bucket, and a descaling solution specifically designed for tankless water heaters (vinegar can also be used).
2. Turn off the power to the water heater at the circuit breaker.
3. Close the shut-off valves on both the cold water inlet and hot water outlet of the unit.
4. Connect the hoses. Attach one hose to the cold water inlet drain valve and the other to the hot water outlet drain valve.
5. Place the ends of the hoses into a bucket.
6. Open the drain valves to drain any remaining water from the unit.
7. Connect the pump (if using). Place the submersible pump into the bucket and connect one of the hoses to the pump’s outlet.
8. Circulate the descaling solution. Pour the descaling solution into the bucket. Turn on the pump (if using) to circulate the solution through the water heater for the amount of time specified in your descaling solution instructions (usually 30-60 minutes). If you’re not using a pump, you can pour the solution directly into the unit using a funnel, let it sit for the recommended time, and then drain it.
9. Flush with clean water. After circulating the solution, disconnect the hoses and flush the unit with clean water until the water runs clear.
10. Close the drain valves, remove the hoses, and reopen the shut-off valves.
11. Turn the power back on at the circuit breaker.

Preventative Maintenance: Regular Flushing

Regular flushing is crucial preventative maintenance. It is recommended to flush your tankless water heater at least once a year, or more frequently if you have hard water.

Fix 3: Verify Adequate Water Pressure – Ensure Proper Activation

Tankless water heaters require a minimum water pressure to operate correctly. If the water pressure is too low, the unit may not activate the heating element, even when a hot water tap is open. The EcoSmart’s flow sensor needs sufficient pressure to register the demand for hot water.

How to Check Water Pressure

You can check your water pressure using a simple water pressure gauge, which can be purchased at most hardware stores. Attach the gauge to an outside faucet or a laundry tub faucet. Open the faucet fully and read the pressure on the gauge.

Adequate Water Pressure Levels

EcoSmart water heaters typically require a minimum water pressure of 30 PSI (pounds per square inch) to operate correctly. Check your EcoSmart model’s specifications for the exact minimum pressure requirement. If your water pressure is below this level, consider consulting a plumber to investigate the cause. Low water pressure can be caused by various factors, such as issues with your main water line, a faulty pressure regulator, or clogged pipes.

Fix 4: Inspect Flow and Temperature Sensors – The Gatekeepers of Heat

As mentioned earlier, the flow and temperature sensors are critical for the proper functioning of your EcoSmart unit. They act as gatekeepers, ensuring that the heating element only activates when there is sufficient water flow and that the water is heated to the correct temperature.

Flow Sensor Function

The flow sensor detects when water is flowing through the unit, signaling the system to activate the heating element. If the flow sensor is faulty or obstructed, it may not register water flow, preventing the heating element from turning on.

Temperature Sensor Function

The temperature sensor ensures the water temperature is correct. It monitors the water temperature as it flows through the unit and adjusts the heating element’s output accordingly. If the temperature sensor is malfunctioning, it may send incorrect readings to the system, preventing the heating element from turning on or causing the water to overheat.

Visual Inspection

While a thorough diagnosis of these sensors may require specialized tools and expertise, you can perform a basic visual inspection (without requiring disassembly) to check for any obvious damage or disconnections.

• Check for loose wires or connectors near the sensors.
• Look for any signs of corrosion or damage on the sensor bodies.
