Understanding the Problem
About this model and what to expect: The Whirlpool WTW5100HW0 is a top-load conventional Whirlpool washer commonly used for household laundry. The most frequent service calls for this model are: won’t start, won’t spin/drain, noisy or shaking, leaks, and fills/overflows. Below are systematic diagnostics and step-by-step repair actions you can take at home. 1) If washer won't start or respond 1.1 Verify basics: confirm unit has power (plug is tight, circuit breaker not tripped). Try another outlet if available. 1.2 Check the lid/lid lock: If the washer won’t start agitate/spin, the lid switch or lid lock assembly is often the cause. Put a rag through the lid and close the lid — press Start. If closing the lid by hand lets it run intermittently, remove and test lid switch for continuity with a multimeter. 1.3 Control and cycles: Try a different cycle and a short cycle. If control panel is unresponsive or shows flashing lights, reset the washer by unplugging for 1–2 minutes and plugging back in. 1.4 Failure of starting after tests: suspect faulty lid switch, control board, or harness. Inspect for burned connectors or water corrosion. 2) If washer fills but won’t agitate or spin 2.1 Check for obstructions: Ensure not overloaded or clothing jammed between tub and basket. 2.2 Motor coupling or drive system: Many Whirlpool top-loads use a coupling between motor and transmission. If you hear motor run but no basket action, check the motor coupling (visual inspection for broken plastic). Replace if worn. 2.3 Check drive belt (if equipped) or transmission/clutch: Inspect for damaged belt or slipping clutch. Replace worn parts. 2.4 Test the motor: With safe precautions, test motor for humming or lack of rotation. A humming motor with no rotation usually points to coupling or transmission problems. 3) If washer won’t drain or won’t spin 3.1 Run the Drain & Spin diagnostic or select Drain/Spin cycle. Listen: is the drain pump running? If you hear nothing, the drain pump or its power/harness may be at fault. 3.2 Inspect drain hose: Remove hose and check for clogs or kinks. Remove the washer standpipe clog in plumbing if present. 3.3 Check pump for debris: Access the drain pump (usually at front/bottom). Remove foreign objects (coins, lint, socks). Try spinning the pump impeller by hand — it should turn freely. 3.4 Test pump electrically: With the washer unplugged then access wiring, test pump for continuity with a multimeter. If no continuity or pump doesn’t run when powered (only for those comfortable and safe with live testing), replace pump. 3.5 If pump is OK but still not draining, check the pressure switch (water level switch) and its air tube for blockages. If switch doesn’t sense low water, it won’t advance to drain/spin. 4) Leaks or overfilling 4.1 Locate leak: Run a short cycle and watch for where water appears (front, bottom, back). Typical leak points are inlet valve, tub-to-hose connections, drain pump, tub seam, and hoses. 4.2 Inspect hose clamps and inlet hoses: Tighten clamps and replace cracked or soft hoses. 4.3 Check water inlet valve: A leaking inlet valve or stuck valve can slow-drip and overfill. Inspect seals around the valve and replace if leaking. 4.4 Inspect tub and tub seal: If leak is from beneath the washer and not a hose or pump, the tub-to-transmission seal or tub crack may be culprit — this is a more advanced repair. 5) Noisy operation, banging, or excessive vibration 5.1 Check leveling: Verify washer is level on the floor and all feet touch. Adjust legs until stable. 5.2 Inspect suspension/agitator dogs and basket bearings: Agitator dogs (if equipped) can wear, causing rumbling on agitation. Worn basket bearings will make loud grinding during spin and require replacing the bearing and seal/tub procedure. 5.3 Look for foreign objects trapped between outer tub and basket. Remove the basket and check for coins or debris. 6) Fills slowly or not at all 6.1 Confirm hot/cold supply valves are fully open. 6.2 Inspect inlet screens: Remove inlet hoses and check screens on the inlet valve for sediment. Clean or replace valve if clogged. 6.3 Test inlet valve solenoids: Use a multimeter to check coil continuity. If no continuity or valve does not open electrically, replace the inlet valve. General step-by-step replacement example (drain pump): - Unplug washer and turn off water. - Tilt washer back or remove front access panel to reach pump. - Place towels to catch water and remove drain hose; expect some water. - Disconnect pump electrical connectors and hose clamps; note hose positions. - Remove pump and inspect impeller; replace pump if jammed or motor not spinning. - Reinstall hoses and connectors, restore power/water, and run test drain cycle. Safety note: Always unplug the washer and shut off water before doing any repairs. If you are uncertain about electrical testing or removing the cabinet, consider hiring a qualified appliance technician. Some repairs (transmission, bearing/tub seal replacement) require special tools and are advanced.

Helpful Repair Tip
To confirm a bad drain pump: run a drain cycle and listen; then remove the drain hose and check for water flow. If the pump runs (you hear it) but no water moves, check for internal pump fault or blocked hoses; if you hear nothing, test pump continuity with a multimeter and replace if open or mechanically seized.
Frequently Asked Questions
How do I reset my Whirlpool WTW5100HW0 washer?
To reset basic electronic issues, unplug the washer or switch off the circuit breaker for 60 seconds, then restore power. This clears many temporary faults. If problems persist after a reset, run a diagnostic cycle (refer to the service manual) or check specific parts such as the lid switch, drain pump, and inlet valve.
Can I replace the drain pump or lid switch myself?
Yes — both are common DIY repairs on this model if you are comfortable working with small appliance electrical connections. Always unplug the washer and turn off water before starting. Remove the appropriate access panel, disconnect hoses and wiring (take photos to help reassembly), replace the part, then test the washer on a drain or spin cycle. If you're not comfortable with electrical testing or internal repairs, hire a qualified appliance technician.
