Dishwasher tub retains standing water at the end of the wash or drain cycle. The pump motor has failed and can no longer force water through the drain hose.
Samsung dishwasher displays drain error code 5E or 5C. This code is triggered when the control board does not detect successful draining within the expected time window, most commonly caused by a failed drain pump.
A grinding, buzzing, or loud humming sound during the drain phase indicates the pump motor is struggling or has seized. Cycle may stop prematurely after the noise.
Unit begins a cycle but shuts off after a couple of minutes with water left inside. The control board detects a drain fault and interrupts the cycle to prevent overflow.
A cracked or worn pump housing or failed o-ring seal can allow water to seep out of the sump area. Replacing the complete drain pump assembly with a new o-ring resolves the leak.
💡 Pro Tip: How to Confirm Your Drain Pump Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher will not drain water at the end of the cycle — standing water remains in the tub
⚠️ Error code 5E (or 5C) displayed on the control panel indicating a drain fault
⚠️ Grinding, humming, or buzzing noise during the drain phase then the cycle stops prematurely
⚠️ Dishwasher starts then shuts off after a few minutes with water still inside
🔍 Technician Tip: Use a multimeter to check for continuity across the drain pump motor terminals. If there is no continuity, or the pump receives 120VAC but still will not run, the pump motor is confirmed failed and must be replaced — drain pumps are not repairable.
