Samsung dishwasher 7E error
Error7E
Samsung identifies 7E as a WaterWall reflector error. Remove obstructions, correct the reflector position, and reseat it only as the official guide shows.
What the code means
The WaterWall reflector cannot move correctly
Switch off power before reaching into the rail. Do not force the vane or operate the dishwasher with a damaged reflector or rail.
Typical symptoms
017E appears on a WaterWall dishwasher
02A pot handle, knife, packing tape, or mis-seated reflector blocks the rail
03The reflector logo may face the wrong direction
Likely causes
Start with the least invasive explanation and stop if the check requires internal electrical or sealed-system access.
01An item obstructs the WaterWall rail
02Packing tape remains after installation
03The reflector is installed backwards or not seated on the shuttle
Safe next steps
- 1Switch off dishwasher power before reaching into the WaterWall rail
- 2Remove the lower rack and check for a pot handle, knife, ladle, or other obstruction
- 3Remove any installation packing tape from the guide rail
- 4Confirm the WaterWall logo faces forward and upward
- 5If the reflector is mis-seated, lift the vane, turn it correctly, and reseat it on the gray shuttle as Samsung shows
Step-by-step repair
- 1Clear the rail and reseat the WaterWall reflector only with power isolated and without forcing it. Restore power for the official two-minute cycle only after the assembly moves freely. Request service if 7E returns or any part is damaged.
