Answer to continue safely
Is it safe to keep using?
No. Do not run the dishwasher with standing water and an active OE code. Continuing cycles can overfill the tub, cause leaks onto the floor, or burn out the drain pump motor.
Can I reset the code?
Yes. Press and hold the Power button for 3–5 seconds to reset. After clearing the underlying blockage, a reset often clears the OE code and allows a normal cycle to complete.
When to stop immediately?
Stop if you notice: Water is leaking onto the floor from the dishwasher base., The drain pump makes a grinding or burning smell during operation..
