Understanding the Problem
What this is: WTW5100HC0 is a Whirlpool top-load washing machine model. Owners commonly see problems such as: washer won’t start, won’t drain or spin, makes unusual noises, vibrates/shakes, leaks, or displays error codes. Below are clear, prioritized diagnostic and repair steps you can follow to find and fix the fault yourself. 1) Safety & preparation: Unplug the washer and turn off the water supply before opening panels. Have basic tools (screwdrivers, nut drivers, adjustable wrench, multimeter) and a towel or small bucket for water. 2) Confirm symptoms and error codes: If the machine displays an error code or blinks lights, note them. If no codes, reproduce the problem (run a drain/spin or quick wash cycle) and listen/observe (fill, agitate, drain, spin). 3) Basic electrical & power checks: - Verify the washer is plugged into a working outlet. Test the outlet with another device or a multimeter. - Check house circuit breaker/fuse. - Try resetting the washer by unplugging 1 minute and plugging back in. 4) Will not start or won’t respond: - Check control lock / child lock is off. - Enter service/diagnostic mode (see manual/tech sheet in back panel) to confirm control board and user interface are responsive. - Inspect the console for visible damage or burned connectors. - Test lid switch/lid lock: a bad lid switch prevents spin/fill. Access the switch and test continuity with a multimeter; replace if no continuity when lid is closed. 5) Won’t drain or won’t spin: - Check drain hose for kinks or clogs and remove any obstruction. - Inspect the drain pump: remove access panel, run a drain cycle and listen—if pump hums or is silent, remove pump and check for trapped items and test pump motor for continuity. - Verify motor coupling/clutch (on beltless designs) or drive belt condition; worn/broken coupler or belt will stop spin. Replace broken belt/coupler. 6) Noisy during wash/spin or excessive vibration: - Inspect suspension (shock absorbers or dampers) and tub bearings: worn shocks cause banging and tub sag. Replace bad shocks. - Check washer feet and leveling; re-level on a solid floor. - Inspect tub drive components: drive motor, pulley, clutch, and bearings. 7) Water fill problems or overfilling: - Check water inlet valve(s) for debris and proper operation; test for continuity and inspect screens. Replace if defective. - Test the pressure/level switch (air dome/pressure hose) for blockage—remove hose and blow through it; ensure proper signal to the control. 8) Leaks: - Inspect door/lid seal, detergent dispenser, hoses (inlet & drain), and tub-to-pump connections. Tighten or replace leaking hoses/clamps. 9) Control board or console faults: - If diagnostics point to electronic faults (persistent error codes after other parts checked), inspect wiring harnesses and connectors for burn marks, replace the user interface board or main control board as indicated. 10) Final test: After replacing suspected parts, reassemble, restore power and water, run a test cycle and watch for issue recurrence. Safety note: Always disconnect power and water before servicing. If you are not comfortable working with electricity, water, or lifting the washer, or if diagnostics point to sealed tub or major motor/bearing replacement, contact a qualified appliance technician.

Helpful Repair Tip
Start by running the washer's diagnostic/service mode (tech sheet under the rear/top panel) and listen during drain/spin: a silent drain pump or a loud grinding during spin usually isolates the pump or suspension components quickly.
Frequently Asked Questions
How do I put my WTW5100HC0 into diagnostic mode?
Diagnostic/service mode procedures vary by model and year. The quickest approach is to locate the tech sheet (paper service manual) behind the control housing or at the back of the washer; it contains the exact key sequence. If you can't find it, unplug the washer for 1 minute, then reapply power and press the cycle selection buttons in a specific sequence noted on the tech sheet to enter diagnostics. If unsure, consult Whirlpool support or the official service manual to avoid mis-entering codes.
Can I replace the drain pump or lid switch myself?
Yes — both are common DIY jobs if you are comfortable removing the access panels and using basic tools. Always unplug the washer and turn off water first. For the drain pump: drain remaining water, remove lower access panel, disconnect hoses and electrical connectors, remove mounting screws, and install the replacement. For lid switch: remove the console or top panel to access the switch, disconnect wiring, remove the old switch and install the new one. If you encounter rusted fasteners, damaged wiring, or sealed assemblies (like a split tub bearing), consider professional help.
