Waterwall reflector fault, in plain terms
Code: 7E
Name: Waterwall reflector error
Reading: the reflector cannot move correctly
Applies to: Waterwall models
Where Samsung sends you
Samsung’s troubleshooting listing offers no steps next to 7E. It points to a separate guide on the Waterwall reflector error, so search for that guide with your model number. After that, a technician is the right person to look the dishwasher over.
Other codes to compare
7C: the bar tries to move and then halts, with no spray
9C1: abnormal voltage puts the unit in protection mode
If 7E remains after you have followed the reflector guide, ring (415) 969-6153 and ask about Samsung dishwasher repair in San Francisco. We will want the model number, the code and the steps the guide had you try.
Model compatibility: Samsung reuses codes across series and model years, so 7E may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
On Waterwall models the reflector is unable to move properly.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
