Understanding the Problem
If your Whirlpool WM3670HVA stops mid-cycle without draining or won't spin, the result is usually standing water in the drum and clothes that stay wet. Drain and spin functions are linked: the washer must remove water before it can enter a proper spin. When one of the components that controls or executes draining/spinning fails, the machine will often pause, flash an error code, or lock up a cycle. Common root causes include a clogged or failed drain pump, a blocked drain hose, a faulty door lock/latch or door-switch assembly preventing the spin from starting, or issues with the drive system or control electronics. Diagnosing the exact cause involves listening during a drain cycle, checking for error codes / diagnostic mode messages, and doing a few simple inspections such as clearing the pump filter and checking hoses for kinks or clogs.
Common Symptoms
Washer fills but will not drain; standing water in drum after cycle; washer won’t advance to spin; loud humming or no sound from pump during drain; error codes or flashing lights indicating drain/door issues.
Common Causes
- Clogged drain pump impeller or foreign object stuck in pump
- Blocked, pinched, or kinked drain hose or standpipe blockage
- Failed drain pump motor (electrical or mechanical failure)
- Faulty door lock/door latch assembly preventing spin from engaging
- Drive system or motor/control board failure (less common)

Helpful Repair Tip
Run the washer’s diagnostic or drain/spin cycle and listen: if you hear the pump motor running and water doesn’t move, suspect a clogged hose or failed pump impeller. If the pump is silent and you get no voltage at the pump during drain commands, test the door lock and main control for faults.
Frequently Asked Questions
How do I access and inspect the drain pump on the WM3670HVA?
Unplug the washer and turn off water. For most front-load Whirlpool units remove the lower front service panel (or access from the rear on some models). Place towels and a shallow pan under the pump area to catch water. Inspect the pump housing for debris, remove visible foreign objects, and try to rotate the impeller by hand. If impeller is jammed, or pump makes grinding noises or won’t run when tested, replace the pump. Always verify correct part number on the existing pump before ordering a replacement.
Should I repair the drain pump/door lock or replace the washer?
If the washer is otherwise in good shape, repairing a failed drain pump or door lock is usually cost-effective—these parts are relatively inexpensive and straightforward to replace. Consider replacement if there are multiple failing components (control board + motor + tub damage), repeated failures, severe rust, or if the washer is older and close to replacement cost. Always get an estimate for parts + labor and compare to the cost of a new unit.
