Samsung dishwasher Waterwall reflector error code 7E or 7C

Make sure nothing is blocking the reflector, such as a pot handle, large knife, or ladle.

If the dishwasher was recently installed, make sure the packing tape has been removed. It runs along the top of the guide rail; remove the bottom rack to easily access the WaterWall assembly.

When the WaterWall reflector is in the correct position, the WaterWall logo will face forward and upwards. 

If the WaterWall reflector is installed incorrectly, lift up on the vane to remove it, turn it around, and reseat it on the gray shuttle on the WaterWall rail.

If the reflector is installed properly but the error code or blinking lights remain, power cycle the dishwasher for two minutes to clear the error code. To perform a power cycle, simply shut the dishwasher's power off at the circuit breaker and then turn it on again.

While the dishwasher cannot be reset, turning the circuit breaker off and on is a good way to clear errors and minor issues.

It is exceptionally rare that this error code requires service. Once the WaterWall vane is assembled correctly and is no longer blocked from moving, the error code will go away (although a power cycle may be required to clear it).

However, if there's any kind of damage or defect to the unit, or if it continues to give the error after you're confident that it is properly assembled and power cycled, then visit our Support Center to request service. Please be aware that if the technician does not find a defect with the unit, that the service visit would not be covered under warranty.
