Yes, for resale value. Homes without dishwashers sell for 2-3% less and take longer to sell. Even if you hand-wash, future buyers expect one. For rentals, it’s absolutely mandatory – you’ll lose quality tenants without one. Modern dishwashers use less water than hand-washing (3 gallons vs 27 gallons).

Noise level (55dB vs 42dB – huge difference), drying performance (plastic stays wet in cheap models), rack flexibility (3rd rack for silverware), wash quality (food disposal vs filters), and lifespan (5-7 years vs 10-15 years). The sweet spot for most homes is $600-800 – quiet enough, stainless tub, good warranty.

Yes, but budget $500-800 for installation. You’ll need: hot water line from under sink ($150-300), drain connection to disposal/sink ($200-400), dedicated electrical circuit ($200-400), and possibly cabinet modification ($100-300). Total project often hits $1,500-2,000 including a basic dishwasher.

Free installation typically only covers basic swap – same size, existing connections, haul away. The $300+ installations include: electrical work, plumbing modifications, cabinet adjustments, or first-time installations. Always ask what’s included. “Free” often becomes $200+ once they arrive and find issues.

Replace if repair exceeds $300. Average lifespan is 10 years, so you’re near the end. New models are significantly more efficient (save $35/year), quieter, and clean better. Common repairs: control board ($200-400), pump ($150-350), door seal ($150-250). Factor in service call ($75-150) and you’re often better off upgrading.

Stainless steel tub ($100-200 extra) – lasts longer, dries better. Quiet operation under 45dB ($200-300 extra) – essential for open floor plans. Third rack ($100-150 extra) – genuinely useful. Skip: WiFi connectivity, specialty cycles, interior lights. Auto-sensing soil levels and adjustable racks come standard on most mid-range models now.
