Front-loading washing machine won't start - expensive repair or replacement needed

Homeowners with malfunctioning front-loading washers (especially Whirlpool/Sears models) face urgent problems: clothes pile up, laundry routines collapse, and they must choose between costly professional repairs ($300-800), DIY troubleshooting that often fails, or replacing the entire appliance ($800-2000+). Current solutions like generic online forums and manufacturer support are slow, unhelpful, and don't provide reliable diagnosis or affordable fixes.
