Dishwasher Not Cleaning or Draining? Whirlpool Pump & Motor W11178672 – Fix Wash & Drain Failure Fast

If your dishwasher leaves dishes dirty, won’t drain, or runs silently with no water circulation, the pump and motor assembly is the most common cause. In most Whirlpool-platform dishwashers, this is caused by a failed wash pump motor that can no longer circulate or drain water through the system. When it fails, dishes come out dirty or wet, standing water remains in the tub after the cycle, and the dishwasher may hum without spraying. ⚡ Primary wash and drain component — failure stops the entire cleaning cycle. Part W11178672 is the genuine OEM replacement that restores full wash pressure, proper drainage, and normal cycle operation.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Dishwasher powers on and the control panel responds normally
• ✔ Door latch and door switch are confirmed working
• ✔ Water supply is confirmed on and inlet valve is functioning
• ✔ ONLY problem is no spray, poor cleaning, or water not draining after cycle

🔧 Common Symptoms

• Dishwasher runs a full cycle but dishes come out dirty or greasy
• Standing water remains in the bottom of the tub after the cycle ends
• Dishwasher hums or buzzes but spray arms don’t rotate or spray
• Wash cycle starts but water pressure is noticeably weak

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this pump and motor assembly restores normal operation immediately.
