Rheem Air Conditioning

The unit emits one beep when you press and hold the WiFi button for 3 seconds, signaling that a soft reset has begun and the unit is attempting to reconnect to the last known network.

Three beeps indicate that a hard reset of the WiFi settings has been initiated by pressing and holding the WiFi button for 5 seconds. This prepares the unit for a new network setup.

This indicates a problem with communication between different components of the water heater system. It may affect its ability to function correctly.

The heating source has switched to electric elements because the compressor is not working correctly. This indicates a potential issue with the compressor or its operation.

The compressor has shut down because its discharge temperature is too high. The unit is using electric elements as a backup heat source. This is often caused by low airflow.

The suction temperature is too low, causing the compressor to shut down. The unit is relying on electric elements for heating. This could be due to a compressor malfunction.

There is not enough water in the storage tank, which has disabled the heating function for safety. This is often an installation issue related to air in the tank.

There may be an issue with the compressor's wiring, causing it to shut down. The unit is defaulting to the electric elements for heating.

The suction temperature sensor has failed, causing the unit to switch to electric elements for heating. The heat pump is disabled due to this sensor malfunction.

The ambient temperature sensor has failed, meaning the unit cannot accurately read the surrounding air temperature. This can affect heat pump operation.

The temperature sensor for the lower heating element has malfunctioned, disabling the heater. The unit cannot accurately measure the temperature in the lower part of the tank.

The temperature sensor for the upper heating element has failed. The unit cannot accurately measure the temperature in the upper part of the tank, potentially disabling the heater.

The evaporator temperature sensor has failed. The heat pump is disabled, and the unit is relying on electric elements for heat due to this malfunction.

The discharge temperature sensor has failed, indicating a problem with measuring the temperature of the refrigerant discharge. The heat pump may be disabled.

A water leak has been detected in the drain pan, likely due to a leak within the unit. The water leak sensor has been triggered.

The condensate drain line is blocked, preventing water from draining. This can cause the unit to stop heating and rely on electric elements.

The unit is indicating an error because the internal shutoff valve is unable to close properly. This may require service to fix the valve or its connections.

The internal shutoff valve is unable to open. This error message indicates a problem with the valve's operation, potentially disabling water flow control.

There is an error with the input signals related to the shutoff valve. This suggests a communication or configuration problem with the valve.

The system is reporting that the shutoff valve has not been installed. If you do not have a shutoff valve, you may need to configure the unit to ignore this.

There is an error with the lower heating element or its relay is stuck in the closed position, potentially causing continuous heating. The heater is disabled.

The upper heating element has an error, or its relay is stuck closed. This could lead to continuous heating and has disabled the heater.

The heating elements may be mis-wired, or the control board may have failed. This has disabled the heater, and electrical connections need to be checked.

The control board's relay for the lower heating element has failed to close. This error disables the heater, and troubleshooting involves checking wiring and components.

The control board's relay for the upper heating element has failed to close, disabling the heater. Check wiring and component resistance.

The ambient temperature is below freezing, which can damage the heat pump. The unit is off to prevent freezing. You need to enable the heater.

The ECO (Energy Cut Off) high-temperature limit has tripped, disabling the heater due to excessively high water temperature. This requires service.

The controller has malfunctioned, and the time clock feature needs to be programmed. The heater is disabled until this is resolved.

The time clock feature is not functioning correctly, meaning the time is not advancing as it should. This could be a controller issue.

A general fault has been detected within the controller. Technical service is required to diagnose and repair the issue.

The controller has reported a fault. This indicates a potential internal issue requiring professional diagnosis and repair.

A fault has been detected in the controller. This error requires a qualified technician to investigate and resolve.

The controller is experiencing a fault. This is a general error message indicating that technical service is needed.

A fault has been reported by the controller. This indicates a problem that needs to be addressed by a service professional.

The temperature protection sensor on the power board has failed, or the controller is overheating. This requires immediate attention from technical service.

One or more alarm codes (ALMCODE 1 through 4) have a value greater than zero. This signifies that the control board has registered a specific alarm or alert condition that requires attention.

The water heater has been disabled because the automatic water shut-off valve failed to reopen after its 30-day self-check. This prevents water flow and heating.

The Fault Indicator light turns on when the control board detects an alarm or alert. This means there is an issue with the water heater that needs attention.

The LeakSense device has detected water, indicating a potential leak. The system automatically shuts off the heating elements and closes the automatic water shut-off valve to prevent further damage.

This indicator lights up when the water temperature poses a risk of scalding. Exercise caution when using hot water from the taps.

The WiFi LED is solid blue, indicating that the unit has successfully connected to the WiFi network.

This is a routine maintenance reminder to clean the air filter. Regular cleaning ensures optimal performance and efficiency.

The water heater is having trouble meeting the demand for hot water. This could be due to open faucets, leaks, or the unit being undersized.

There is an error with the WiFi chip's communication. This prevents the unit from connecting to or maintaining a stable connection with your network.

A fault has been detected within the controller. This requires professional diagnosis and repair.

The water heater is providing an alert because the automatic water shut-off valve did not close properly during its self-check. This could indicate a problem with the valve's sealing mechanism.

The Wi-Fi indicator is blinking, which means the water heater is in the process of connecting to your Wi-Fi network or is in provisioning mode.

The WiFi LED is blinking, indicating that the unit is in a mode ready to begin the WiFi setup process using the EcoNet Application.
