# Samsung dishwasher error code 7E

### What 7E means on this make

This code belongs only to WaterWall machines, where a reflector sweeps back and forth across the bottom of the tub to make a wall of water. When it cannot move properly the machine says so. The commonest cause is not mechanical failure at all — it is a pan handle, a long utensil or a fallen item in the lower rack blocking its track.

### Where this appears, and why not to clear it

On the appliance’s own display. Samsung reports errors two ways: machines with a digital display show a code, and the same machines without one blink their cycle lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power — Samsung asks for this itself on its refrigerator and dishwasher pages, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has.

### What to do about it

- Open the door and look along the bottom of the tub for anything in the reflector’s path.
- Check the lower rack is loaded so nothing hangs below it.
- Move the reflector gently by hand; it should travel freely end to end.
- If nothing is in its way and it will not move freely, the drive is the repair.

### Where this goes next

The job this usually becomes is [waterwall reflector repair](/services/waterwall-reflector-repair/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 506-1256](tel:+13055061256) and describe what the panel is doing before booking anything.
