Understanding the Problem
If your Maytag MVWB766FW1 fills but won’t drain or spin, the washer will leave clothes soaking wet and may display error indicators or make a humming sound. The most frequent causes are a blocked drain path (hose or pump), a failed drain pump (electrical failure or jammed impeller), or an electronic/door-interlock fault that prevents the spin cycle from starting. Mechanical problems in the drive/gearcase or clutch can also stop the tub from spinning even if the washer attempts to drain. Diagnosing the symptom efficiently involves isolating whether water can be removed (drain function) and whether the basket can be turned by the motor (spin function). Many failures are simple — an obstruction in the drain hose or pump or a stuck object in the pump — and can be cleared without replacing major parts. When electrical components fail (pump motor, lid lock/switch, control board) or internal drive components are worn, repair or part replacement is required.
Common Symptoms
Water remains in the tub after the cycle completes; washer won’t progress to or complete the spin cycle; humming or grinding noises during drain attempts; error codes or flashing lights; wet, heavy laundry at cycle end.
Common Causes
- Clogged or kinked drain hose or foreign object jammed in the drain pump
- Failed or electrically defective drain pump (impeller jammed, motor no longer runs)
- Faulty lid lock/lid switch, wiring, or control board preventing the washer from entering drain/spin

Helpful Repair Tip
Run a Drain & Spin or Diagnostic cycle and listen: if you hear the pump run but water stays, check hoses and pump for blockages. If the pump is silent and has no continuity, it's likely the pump motor; if the washer refuses to enter spin, test the lid lock/switch for continuity with a multimeter.
Frequently Asked Questions
How do I check if the drain pump is bad?
First unplug the washer and remove the lower access panel to inspect the pump and hoses for visible blockages (coins, socks, lint buildup). Manually turn the pump impeller (if accessible) to see if it’s jammed. If there’s no blockage but the pump doesn’t run during a drain cycle, test the pump motor for continuity with a multimeter; an open circuit indicates a failed pump. Also verify the pump is receiving voltage during a drain command — if it is and doesn’t run, replace the pump.
Can I fix this myself or should I call a technician?
You can handle simple checks yourself: clear clogs from the drain hose, inspect and remove debris from the pump, and test the lid switch with a multimeter. These tasks require basic hand tools and safety (unplug the washer). For electrical diagnosis (confirming voltage to the pump), replacing control boards, or internal gearcase/drive repairs, hiring a qualified appliance technician is recommended. Typical parts+labor for a drain pump replacement run roughly $150–$350 depending on location and whether additional repairs are needed.
