This is a motor / drive code. Codes and wording can vary by model, so check your owner's manual for your model number.
How to fix Samsung WaterWall dishwasher error code 7E (safe owner checks)
- Write down the code and model number. Note exactly what the display shows (7E) and copy the full model number from the rating label, so you can confirm this chart applies to your waterWall dishwasher and order the right parts.
- Remove the packing tape on. Remove the packing tape on the water wall vane if not removed during installation.
- Do a power reset. Unplug the appliance or switch off its breaker for one minute, then restore power and try again. If the code clears and stays away, it may have been a one-off fault.
- Test and decide. Run a short cycle or restart and watch the display. If 7E comes back after these checks, stop using the dishwasher for this function and call a technician, because the remaining causes need meters or part replacement.
The first and last steps (and the power reset) are general owner checks added by ErrorCodePro; the rest follow the Samsung WaterWall dishwasher error-code chart published by Sears PartsDirect, rewritten for safe owner use.
