Understanding the Problem
The Whirlpool WM3670HVA is a front-load washer that commonly experiences a handful of recurring issues as it ages: failure to drain or spin, door lock or latch faults, control board or electronic errors, and occasional leaks or loud noises. Many of these problems show clear symptoms (error codes, no water draining, or the door refusing to lock) and can be diagnosed without full disassembly. Because the WM3670HVA uses electronic controls, a failed control board, faulty door lock, or a clogged/failed drain pump are frequent culprits. Mechanical wear (motor bearings, shock absorbers) or installation issues (unleveled machine, obstructed drain) can produce vibration, noise, and agitation problems. Start with the simple checks—error codes, hoses, filters, and the door lock—before replacing major components.
Common Symptoms
Washer won't drain or spin; door won't lock or unlock; persistent error codes; loud grinding or banging during spin; water leaks under the machine; machine won't start or intermittently stops mid-cycle.
Common Causes
- Clogged or failed drain pump (debris, foreign objects, or pump motor failure)
- Faulty door lock/latch assembly (prevents cycle start or causes door-error codes)
- Bad main control board or wiring/connectors (erratic behavior, unreliability or multiple unrelated errors)

Helpful Repair Tip
Start by running the washer's diagnostic/service mode and note any error codes, then check the drain pump filter and door lock operation — these two checks identify the majority of common faults quickly. Always confirm the model and serial tag on the washer to match exact replacement part numbers.
Frequently Asked Questions
How do I check error codes or run diagnostics on the WM3670HVA?
The WM3670HVA supports a built-in diagnostic/service mode. To enter diagnostics, typically you start with the washer off, then press a specific sequence of buttons (varies by model) to display fault codes and test individual components. Because button sequences differ, consult the service manual for WM3670HVA or provide the exact model/serial and I can give the step-by-step sequence. The displayed fault codes will point you to the likely failing subsystem (drain, door lock, motor, etc.).
Is it worth repairing a WM3670HVA or should I replace the washer?
If the repair is limited to a drain pump, door lock, or a single replaceable electronic board, repair is usually cost-effective compared with replacing the entire washer. However, if you face multiple major failures (motor bearings, multiple electronic boards) or repeated repairs, replacement may be more economical. Compare the estimated parts+labor cost to the current value/age of the washer — machines older than ~8–10 years often approach replacement thresholds.
