Understanding the Problem
The Whirlpool WTW5100HW2 is a top-load high-efficiency washer. Over time owners commonly see problems such as the washer not starting, not draining or spinning, loud noises during spin, leaks, or error codes. Below are the likely causes and practical step-by-step diagnostics and repair instructions for the most common failures. 1) Won’t start / won’t agitate or spin: check power and lid lock first. Steps: 1.1 Unplug the washer and verify outlet with a known-good device or voltage meter (120VAC). 1.2 Inspect the lid lock / lid switch for physical damage; run a diagnostic or attempt a cycle — if the washer doesn’t lock the lid or shows a lid error, remove the top panel, access the lid lock assembly and inspect wiring. 1.3 Test lid lock for continuity with a multimeter (with lid closed and switch activated). Replace lid lock if no continuity when it should be closed. 1.4 If lid lock is good, check the control board connections and harness for burned connectors or loose wires. Re-seat connectors and run a test. 1.5 If power is present and lid lock/control are OK but there’s still no motor action, test the motor and motor capacitor (if fitted) and check motor drive components. 2) Won’t drain or won’t spin: check drain pump, hoses, and pressure switch. Steps: 2.1 Put washer into a drain/spin cycle and listen — a humming pump with no water movement suggests a jammed pump or bad motor; silence suggests pump not powered or open. 2.2 Unplug washer, turn off water, and remove the lower front access panel. 2.3 Inspect and remove any debris from drain hose and pump inlet — common obstructions are coins, socks, and buildup. 2.4 Test pump motor for continuity with a multimeter. If pump hums but won’t turn, remove and inspect impeller; replace pump if impeller is damaged or motor has no continuity. 2.5 Check the pressure (water level) switch and its air tube — a clogged air tube or faulty pressure switch can prevent the washer from advancing to drain/spin. 3) Loud noise or vibration during spin: check tub bearings, drive components and shock absorbers. Steps: 3.1 Run an empty spin cycle and note where the noise originates (top vs. bottom). 3.2 Excessive movement usually means worn shocks/dampers or suspension springs; replace faulty dampers. 3.3 A grinding or rumbling from the center often indicates a bad tub bearing or a damaged drive hub/agitator coupling — these require more extensive disassembly to replace. 4) Leaks: inspect hoses, door seal, and pump. Steps: 4.1 Visually inspect water inlet hoses and clamps for wetness and tighten or replace hoses as needed. 4.2 Check the tub-to-pump hose and pump seals for cracks or loose clamps. 4.3 If leak appears under the washer near the center, the tub seal or outer tub cracks may be the cause — these are major repairs. 5) Error codes or “F” codes: consult the service tech sheet for this model. Steps: 5.1 Enter diagnostic mode (consult service manual for WTW5100HW2) to read fault codes. 5.2 Use the code to isolate the failed circuit (lid lock, motor, water valve, pressure switch, heater if equipped). Safety note: Always unplug the washer and shut off the water before doing any internal inspection or repairs. Wear gloves and safety glasses. If you are not comfortable with electrical testing or removing the outer tub, contact a qualified appliance technician.

Helpful Repair Tip
To confirm a failed drain pump: run a drain/spin cycle and listen — if you hear a humming motor but no water moves, remove the lower front panel and check for jammed debris at the pump impeller. If the impeller spins freely but the pump has no continuity, replace the pump.
Frequently Asked Questions
How do I find the exact replacement part for my WTW5100HW2?
Locate the washer’s model and serial tag (usually on the back, inside the lid, or on the console underside). Use that info on Whirlpool’s parts website or a reputable parts vendor to confirm the OEM part number. Don’t rely only on the washer model — some parts are serial-specific.
Is it worth repairing a WTW5100HW2 or should I replace the washer?
Minor repairs like replacing a drain pump, lid lock, inlet valve, or dampers are usually cost-effective. Major repairs — outer tub, gearbox, or motor/bearing replacements — can be expensive; compare the repair estimate to current replacement washer prices and factor in the appliance age and energy efficiency. If the washer is under 7–10 years and the repair is under ~40% of replacement cost, repair often makes sense.
