If your Rheem tankless water heater is displaying the error code P1, it means that there is a problem with the unit’s combustion chamber. This can be caused by a number of things, including a dirty or blocked burner, a faulty igniter, or an obstruction in the flue. If you’re getting the P1 error code, the first thing you should do is check the burner and igniter for any dirt or debris.

If they’re clean, then the next step is to check the flue for any obstructions. If everything looks clear, then it’s possible that the P1 error is simply due to a faulty igniter. In this case, you’ll need to replace the igniter before your water heater will work again.

What is Code 11 on a Rheem Tankless Water Heater?

If you have a Rheem tankless water heater, you may have noticed a code 11 on the display. This code indicates that the unit is in standby mode and is not providing hot water. There are a few reasons why this may be happening:

1. The water heater may be turned off at the circuit breaker or gas valve. Check to make sure both are turned on. 2. The inlet water temperature may be too low for the unit to operate.

Tankless water heaters require a minimum inlet water temperature of 50 degrees Fahrenheit (10 degrees Celsius) to work properly. If the inlet water temperature is below this, the unit will go into standby mode to prevent damage. 3. The outlet water temperature may be set too low.

The default setting for most Rheem tankless units is 120 degrees Fahrenheit (49 degrees Celsius). If you have lowered this setting, the unit will go into standby mode once it reaches that temperature to prevent scalding. Increase the outlet water temperature setting until the code goes away.

4. There may be something blocking the flow of exhaust gases from the unit.
