Samsung Dishwasher Error Code PE — Half Load Function Error
What this means
The PE error code indicates an issue with the dishwasher's half-load or zone wash diverter mechanism. This mechanism directs water to specific sections of the dishwasher. When it fails, the dishwasher may not properly route water to the selected zone, or the diverter motor may not respond.
Step-by-step fix
3 stepsReset the dishwasher
Turn off the circuit breaker for 5 minutes. Turn it back on and try running a full cycle (not a half-load/zone wash cycle) to see if the error clears.
If the error only appears with the half-load or zone wash option, the diverter may be the issue.
Check for obstructions
Remove the lower rack and check that no dishes or debris are interfering with the water diverter mechanism at the bottom of the tub.
Run a diagnostic cycle
Consult your owner's manual for how to enter the diagnostic mode. Run the diagnostic to test the diverter motor independently.
The diagnostic mode code varies by model — it's usually a specific button combination.
When to call a professional
If the diverter motor or mechanism has failed, a technician should replace the diverter assembly, which is located under the tub.
