Understanding the Problem
Brief overview: The Whirlpool WFW6620HW2 is a front-load washer that commonly experiences a handful of repeatable issues: not draining, not spinning/unbalanced loads, door-lock (lid lock) errors, loud bearing or motor noises, and leaks. Below are prioritized diagnostic steps and concrete repair actions for each common failure mode. Follow the numbered tests in order — they go from easiest (filter/hoses) to most invasive (motor/tub bearings). 1) Not draining / OE error a) Check the drain hose and standpipe for kinks or clogs. Remove hose from standpipe and try to blow or run water through it. b) Clean the drain pump filter/trap (if accessible). Many front-loaders have a small access panel at the bottom front with a drain filter and emergency drain hose — pull the small drain hose into a bucket and remove debris. c) Run a drain-only diagnostic (factory service or drain cycle) and listen for the pump. If pump hums but no water moves, the impeller may be jammed or the pump is failing. d) Inspect the drain pump inlet for lodged items (coins, fabric). If clogged, remove debris and retest. e) If pump does not run or has no continuity, replace the drain pump. Practical fix: Replace drain pump (see parts list) or clear obstruction. Reassemble and run a drain/spin test. 2) Washer won't spin or gives UE (unbalanced) error a) Confirm load balance: try a small mixed load or redistribute clothes by hand, then run spin only. b) Check the door lock. If the washer won’t lock, it won’t start the spin. Listen for the lock actuator when starting a cycle. c) Check drain — washer won't spin if it can't drain. Clear filter/pump if needed. d) Inspect shocks/suspension and tub dampers for wear (washer rocks excessively when paused mid-cycle). Replace worn shocks or suspension rods. e) If motor runs but tub doesn't spin, check the drive belt / motor coupling (if present) or motor control. Replace belt or coupling as needed. Practical fix: Rebalance loads first. Replace door lock or suspension/shocks if visibly damaged; replace belt/motor coupling or motor if mechanical failure is confirmed. 3) Door lock / CL or Lid switch errors a) If the door won’t latch or the machine flashes a door-related error, open service mode to read the lock test or simply observe: when you press start, do you hear a click at the door? b) Inspect the strike and latch for broken plastic or foreign objects preventing engagement. c) Test the door lock for continuity with a multimeter — no continuity when it should be locked means replace the lock assembly. Practical fix: Replace the door lock/latch assembly if it fails the continuity test or shows physical damage. 4) Loud noise / grinding or rumbling a) Run an empty spin and listen: noise during spin often indicates bad tub bearings or a failing motor/drum seal. b) Remove the front panel and try to turn the drum by hand — roughness, grinding or metal-on-metal feeling indicates bearing failure. c) If bearings are bad, you’ll usually see grease in the tub seam or water leaks. Replace the tub bearing and seal kit or the entire tub assembly depending on your skill and cost considerations. Practical fix: Replace bearings/seals and clean and re-lubricate per kit instructions; if rusted or heavily damaged, replace outer tub. 5) Water leaks a) Inspect door seal (boot) for tears, trapped items or mold causing poor seal. Replace the door boot if cut or torn. b) Check inlet hoses and clamps for obvious leaks; tighten or replace as needed. c) Inspect hose clamps and drain hose connection at the pump and tub. Replace split hoses. Practical fix: Replace the door boot, faulty hose, or clamp. Tighten connections and retest. 6) Error codes and entering diagnostics a) Common front-load codes: OE (drain), UE (unbalanced), F0E1/F0E2 (control board/water issues vary by model). Consult service manual for exact codes for WFW6620HW2. b) To run diagnostics: With washer off, press specific buttons (model-specific) to enter diagnostic mode — this reads stored fault codes and runs individual component tests. If unsure, look up the WFW6620HW2 service manual or call tech support. Safety note: Always unplug the washer and shut off the water supply before opening panels or working on internal parts. Drain any standing water into a bucket before removing components. If you’re not comfortable with electrical diagnostics or disassembling the tub, hire a qualified technician.
Common Symptoms
Washer won't drain (OE), won't spin or spins intermittently, door lock errors or washer won't start, loud rumbling/grinding on spin, visible water leaks from the door seal or bottom.
Common Causes
- Clogged drain hose or pump trap
- Failed drain pump (motor or impeller jammed)
- Faulty door lock/latch assembly
- Worn suspension/shocks or tub bearings
- Drive belt or motor/motor control failure
- Torn door boot or damaged hoses/clamps
- Control board/software errors

Helpful Repair Tip
To confirm a bad drain pump: start a drain cycle and listen — if you hear a hum but no water is expelled, the pump is likely jammed or failed; if you hear nothing, check for 120V at the pump during the drain cycle before replacing it.
Frequently Asked Questions
How do I enter diagnostics / read error codes on the WFW6620HW2?
This model has a factory diagnostic mode that displays stored fault codes and can exercise individual components. The exact button sequence is model-specific; check the service manual for WFW6620HW2. If you don’t have the manual, you can often find codes by observing the control display after a failed cycle or by calling Whirlpool support. Running diagnostics helps pinpoint whether the issue is electrical (board, motor) or mechanical (pump, lock).
Is it worth repairing a noisy tub bearing vs replacing the whole washer?
Tub bearing replacement is labor-intensive (requires disassembling the washer and removing the tub) but less expensive in parts than a new washer. If the washer is otherwise in good condition and under ~8–10 years old, replacing bearings/seals can be worthwhile. If there are multiple failing components (board, motor, tub rust) or the machine is older, replacement may be more cost-effective.
