Understanding the Problem
The Whirlpool GTW335AS0WW is a top-load, agitator-style washer. Common repair needs are: not draining, not spinning or agitating, not filling, loud noises, and leaks. Below are practical, prioritized diagnostic and repair steps you can follow at home. 1) Safety & preparation: unplug the washer and turn off the water supply before working on any internal components. Have basic tools ready: screwdrivers, pliers, multimeter, bucket, towels. 2) If the washer won't drain or spin (very common): a) Check the drain hose for kinks, clogs, or high loop incorrectly installed — remove hose and run water through it into a bucket to confirm flow. b) Inspect the pump area — many clogs live at the pump inlet. Tip: disconnect power, remove the lower access panel or tilt the washer back (support it) and remove the drain pump hose to check for obstructions (coins, lint, small garments). c) Test the drain pump electrically with a multimeter for continuity; if it has continuity but runs loudly or doesn't pump, replace the pump. d) If the pump is fine, test the motor coupling/drive system (some Whirlpool top-loads use a coupling or belt and clutch). A broken coupling or worn clutch will allow the motor to run but not spin the basket — replace the coupling/clutch assembly per model instructions. 3) If the washer won't fill or fills slowly: a) Verify both hot and cold water valves are fully open. b) Remove the inlet hoses and check mesh screens for debris; clean screens if dirty. c) Test the water inlet valve solenoids with a multimeter for continuity; replace the inlet valve assembly if one or more solenoids are open or the valve leaks. 4) If the washer is noisy (grinding, humming, squealing): a) Determine whether noise occurs during spin, agitate, or drain. b) If noise during drain — inspect and replace pump if impeller damaged. c) If noise during spin — inspect tub bearings, spider, motor bearings, and suspension/shock absorbers. Worn shocks or suspension springs cause banging and excessive movement; replace worn shocks/springs. d) Check for foreign objects between the inner and outer tubs (small items or hard objects) and remove them. 5) If washer stops mid-cycle or shows error codes: a) Note any flashing or F-codes and consult the model-specific code list (some codes point to lid lock, motor control, or control board issues). b) Test the lid switch/lock: the washer will not begin high-speed spin if the lid lock assembly is faulty. Replace the lock/switch if it fails continuity when closed. 6) If the washer leaks: a) Inspect inlet hose connections, drain hose, tub-to-pump hoses, and the door/lid seal area for cracks or loose clamps. b) Tighten hose clamps or replace cracked hoses/pump seals. c) If the tub or outer tub is cracked, replacement of the tub assembly may be required. 7) Basic replacement steps (example: drain pump or lid lock): a) Unplug the washer and turn off water. b) Access the component (lower access panel for pump; top or front access for lid lock depending on model). c) Take photos of wiring and hose locations before disconnecting. d) Disconnect wiring harness and hoses, remove mounting screws, install the new part, reconnect hoses/wiring, secure panels, restore power/water, run a test cycle. 8) Final checks: after repair, run a full agitation and spin/drain cycle with a small load to confirm the problem is resolved and there are no leaks. Safety note: always disconnect power before working on the washer. If the repair requires removing the cabinet, drum, or control board and you are not comfortable performing these steps, call a qualified appliance technician.

Helpful Repair Tip
To confirm a bad drain pump: run a drain cycle and listen — if you hear the motor humming but no water flow and the pump inlet is clear, replace the pump. If the motor spins but the tub doesn't rotate, suspect the drive coupling or clutch.
Frequently Asked Questions
My washer fills but won't start agitating or spinning. What should I check first?
First check the lid lock/switch — if the washer thinks the lid is open it will not run the motor at full speed. Next, listen: if you hear the motor humming but the tub doesn't move, the drive coupling or clutch may be broken. Also check for error codes and make sure the selected cycle includes agitation/spin.
How do I know if the drain pump is clogged or needs replacement?
Remove power and access the pump inlet. If you see debris (coins, small items, lint) remove it and test a drain cycle. If debris was cleared and the pump still doesn't move water or the pump motor hums without turning, test the pump for electrical continuity; if there's continuity but no mechanical action, replace the pump.
