Tankless water heaters are a type of heating product that allows you to quickly heat water, usually using a solar panel. Tankless water heaters heat the water by heating it with solar energy, and because of the low energy costs involved, they are often considered more environmentally friendly than traditional water heaters.
But tankless water heaters can still throw error codes. In many cases, the error codes associated with Rheem tankless water heaters cause a lot of trouble. This is one of the most common error codes that are associated with the Rheem tankless water heaters, and it provides some helpful tips on how to fix them.
If there is no water that will flow through the inlet filter of your water heater, you will receive an error code P1 (Problem 1) when trying to start the water heater. If the water flow sensor is bad, the water heater will not work. If this sensor does not function, the unit will fail.
If the water heater does not start, tell the plumber to do a quick clean of the inlet filter while water pipes from the cold water supply to the water heater.
If you have cleaned the filter, try running hot water from the tap to see if the water is flowing freely. If that still does not work, try increasing the flow rate of water. If it still does not work, it may be time to replace the water flow sensor.
Error code c7 indicates that something is not working properly between the remote control and the tankless unit. Rheem Tankless Water Heaters will give you this error code if there is a problem with the remote control, the PCB, or the wire that connects the tankless water heater to the remote control.
Start by checking the remote control. If the remote control is not working, it is time to replace the water heater. It is possible that the remote control is not working properly and you may need to replace the whole unit.
Check that the remote control on your water heater is working correctly by unplugging it from the power supply and pulling the cover off. Locate the two wires that are connected to the remote control to check if the device is operating properly.
Disconnect the power cable that connects your remote control to the water heater and plug the water heater into an electrical outlet. If the water heater starts to work, it is most likely that the remote control is faulty or that the wires between the remote and the tankless unit are damaged.
E5 on a Rheem Tankless Water Heater means that the water is flowing very fast. It means that the water flow rate is too high and the desired water volume is greater than your desired temperature. You will have to reduce the flow rate to stop it from happening.
