Replacing a dishwasher can feel overwhelming, especially when you have no idea what to expect. Most people either overpay because they trust the first quote they get, or they buy the wrong unit and regret it fast. This guide breaks down every cost, every factor, and every way to save money, so you walk in knowing exactly what you’re doing.
Key Takeaways: Replacing a dishwasher typically costs between $400 and $1,500, depending on the unit you choose and who installs it. The appliance itself runs $300 to $1,200, while labor adds $100 to $300 on top. If you need new plumbing or electrical work, that pushes the total higher. Buying during holiday sales, skipping unnecessary features, and comparing installer quotes can save you a solid chunk of cash.
What is the Average Cost to Replace a Dishwasher?
Most homeowners spend somewhere between $400 and $1,500 total when replacing a dishwasher. That number covers the appliance and basic installation. But the range is wide because dishwashers vary a lot, from no-frills budget models to fancy units with ten wash cycles and a Wi-Fi app.
The appliance alone usually costs $300 to $1,200. A decent mid-range model sits around $500 to $700. That’s the sweet spot for most families. You get solid performance, quiet operation, and good energy efficiency without paying for features you’ll never use.
Labor adds $100 to $300 for standard installation. That’s when your plumbing, electrical, and cabinet space are already set up and ready. If anything needs adjustment, the price climbs. A good plumber or appliance installer can typically swap a dishwasher in an hour or two.
Always ask for a written quote before anyone starts work. It sounds obvious, but a lot of people skip it and end up surprised at the final bill.
- Budget dishwashers: $300 to $500
- Mid-range dishwashers: $500 to $900
- High-end dishwashers: $900 to $1,200+
- Standard installation labor: $100 to $300
- Extra plumbing or electrical: $150 to $500 more
- Total average replacement cost: $400 to $1,500
Full Breakdown of Dishwasher Replacement Costs
Cost of the Dishwasher Unit Itself
The biggest chunk of your budget goes to the appliance. You can find entry-level dishwashers from brands like GE or Whirlpool starting around $300. They clean well, but they tend to be louder and lack features like adjustable racks or delay start.
Mid-range models from Bosch, KitchenAid, or Maytag usually land between $600 and $900. These run quieter, use less water, and hold up better over time. Most families find this range hits the right balance between cost and quality.
Premium models from brands like Miele or high-end Bosch lines go above $1,000, sometimes well above. They’re nearly silent, incredibly efficient, and built to last 15 or more years. If you cook a lot and run your dishwasher daily, the long-term savings on water and energy can justify the higher price.
- Budget models: $300 to $500, louder, fewer features
- Mid-range models: $600 to $900, quiet and efficient
- High-end models: $1,000 to $2,000+, premium build and performance
- Bosch is the most recommended brand in the mid-to-high range
Installation Labor Costs
Labor is the second biggest cost. Most dishwasher installation services charge $100 to $300 for a straight swap. That means they pull out the old unit, slide in the new one, connect the water supply, the drain line, and the power, and they’re done.
If you hire a general handyman, you might pay less, around $75 to $150. But for anything involving plumbing or electrical, a licensed plumber or electrician is worth the extra cost. The last thing you want is a slow leak under your cabinet that you don’t catch for weeks.
Big box stores like Home Depot and Lowe’s often include installation in the purchase price or offer it at a discount. It’s worth checking their dishwasher installation packages before hiring separately. Sometimes bundling saves you $50 to $100 right away.
- Handyman installation: $75 to $150
- Professional plumber or installer: $150 to $300
- Big box store bundle deals: often cheaper than hiring separately
- Always confirm what’s included before agreeing to a price
Plumbing and Electrical Upgrades
Not every replacement is a simple swap. If your old dishwasher was from the 1990s, chances are the hookups don’t meet current standards. Old galvanized pipes, outdated wiring, or a missing air gap can all add to your bill.
A plumber updating water supply lines or replacing a drain connection typically charges $150 to $400 for that work alone. Electrical upgrades, like adding a dedicated circuit, can cost $200 to $500 depending on how much work is involved and your local electrician’s rate.
If your kitchen has never had a dishwasher before, you’re looking at a bigger job. Running new water lines, a drain, and electrical from scratch can add $500 to $1,000 or more. That’s a real cost to factor in if you’re doing a new dishwasher installation in an older home.
- Updating supply lines: $150 to $300
- Drain line repair or rerouting: $100 to $250
- New electrical circuit: $200 to $500
- Full new hookup from scratch: $500 to $1,000+
Old Dishwasher Removal and Disposal
Pulling out the old unit is part of most installation quotes, but disposal sometimes costs extra. Some installers haul it away for free. Others charge $25 to $75 to take it off your hands.
If you bought through Home Depot or Lowe’s, they often offer appliance haul-away service for a small fee, usually around $20 to $30. That’s usually the easiest option. You don’t have to wrestle a heavy appliance to the curb or figure out where your local dump is.
You can also sell the old dishwasher on Facebook Marketplace if it still works. Even a ten-year-old unit in decent shape can fetch $50 to $100. That money goes right back into your replacement budget.
- Installer haul-away: $0 to $75 depending on who you hire
- Big box store haul-away: $20 to $30
- Selling the old unit online: $50 to $100 if it still runs
- Municipal bulk trash pickup: often free, but check your local rules
Extended Warranties and Protection Plans
Once you’ve spent $600 or more on an appliance, a warranty starts to make sense. Most new dishwashers come with a one-year manufacturer warranty. Some brands like Bosch or Miele offer two to three years on parts and labor.
Retailers push extended warranties hard, and they’re usually overpriced. A three-year plan from a big box store might cost $100 to $200. That said, if you’re buying a high-end model and plan to keep it for ten-plus years, some coverage can be worth it.
A better option is checking whether your home warranty plan covers appliances. Many do. If you already pay for one, your dishwasher replacement might be mostly covered, minus a service call fee of $75 to $125.
- Manufacturer warranty: usually 1 to 3 years, included free
- Retailer extended warranty: $100 to $200 for 3 years
- Home warranty coverage: check your plan, could save hundreds
- Skip the extended warranty if the manufacturer’s coverage is already strong
Hidden Costs Most People Miss
The quote looks reasonable, then a few extras pop up. It happens a lot. The installer finds the cabinet opening is slightly too small and needs trimming. Or the old drain hose is too short for the new unit. Small things add up fast.
A dishwasher installation checklist helps here. Before anyone shows up, measure your cabinet opening carefully (standard is 24 inches wide, 24 inches deep, 34 inches tall), check that your water shutoff valve works, and confirm you have an outlet or hardwired connection nearby.
Also budget for a new supply line hose if yours is old. They cost $15 to $30 and are cheap insurance against leaks. Some installers include them. Many don’t. Ask ahead of time so you’re not caught off guard.
- Cabinet modifications: $50 to $200
- New supply line hose: $15 to $30
- Permit fees (some areas require them): $50 to $150
- Extra labor if old unit is stuck or corroded: $50 to $100 more
Does Replacing a Dishwasher Add Value to Your Home?
It can, but not always in the way people expect. A new dishwasher won’t dramatically boost your home’s sale price on its own. But a broken or missing one can actually hurt you during a home sale, because buyers notice it and factor in the replacement cost.
If you’re selling soon, a mid-range dishwasher replacement for home sale makes more sense than a luxury upgrade. Buyers care that it works, looks clean, and fits the kitchen. They’re not paying extra for a Wi-Fi-connected wash cycle.
For everyday living, the value is more practical. A new energy-efficient dishwasher uses around 3 to 4 gallons of water per cycle, compared to older models that use 10 or more. Over a year of daily use, that difference adds up on your water bill.
So yes, replacing a dishwasher adds value. Just don’t expect it to return dollar for dollar at resale. Think of it more as a comfort upgrade with a small side benefit when it comes time to sell.
- New dishwashers use far less water than older models
- Energy Star models save $35+ per year on utility bills
- Buyers expect working appliances, so a broken unit hurts you at resale
- A mid-range replacement is usually enough to satisfy buyers
- High-end upgrades rarely return full cost at resale
- The real value is in daily convenience and lower utility bills
How Long Does a Dishwasher Last Before Replacement?
The average dishwasher lasts about 9 to 12 years. That’s the standard answer, but it depends a lot on the brand, how often you run it, and how well you maintain it.
Budget models tend to sit at the low end of that range. A $350 dishwasher that runs once a day will likely need replacing around year 8 or 9. Mid-range models from Bosch or KitchenAid often go 12 to 15 years with basic upkeep. High-end Miele dishwashers are built to hit 20 years, and many do.
The warning signs are pretty clear. Dishes come out dirty or still wet. The door latch stops holding. You hear grinding, banging, or a motor that sounds like it’s struggling. Water pools at the bottom after a cycle. Any one of these means trouble, and two or more usually mean it’s time to shop.
Repairs can extend the life of a dishwasher, but only up to a point. If the repair costs more than half the price of a new unit, replacement almost always makes more financial sense. That’s a good rule of thumb for any appliance.
- Average dishwasher lifespan: 9 to 12 years
- Budget models: 7 to 10 years
- Mid-range models: 12 to 15 years
- High-end models: 15 to 20 years
- Repair vs. replace rule: if repair costs over 50% of new unit price, replace it
- Regular cleaning and filter maintenance can add years to any model
Final Thoughts
I hope this gives you a clear picture of what to expect before you spend a single dollar. Replacing a dishwasher doesn’t have to be stressful. Know your budget, measure your space, get two or three quotes, and don’t overpay for features you won’t actually use. A good mid-range model, installed properly, will serve you well for years.

Frequently Asked Questions (FAQs)
Is it cheaper to repair or replace a dishwasher?
If repair costs more than half the price of a new unit, replace it. A $150 fix on a 5-year-old machine makes sense. A $400 repair on a 10-year-old model usually does not.
Can I install a dishwasher myself to save money?
Yes, if you’re handy and the hookups are already in place. But if plumbing or electrical is involved, hire a pro. A bad DIY connection can cause leaks, water damage, or a tripped breaker.
Are Bosch dishwashers worth the extra cost?
For most people, yes. Bosch dishwashers run quieter, clean better, and last longer than budget brands. The 300 series around $700 is one of the best values in the dishwasher market right now.
Do dishwasher prices go on sale?
Yes, and the savings can be real. Black Friday, Memorial Day, and Labor Day are the best times to buy. You can save $100 to $300 on a mid-range model if you time it right.
Is a permit required to replace a dishwasher?
It depends on your location. Some cities require a permit for plumbing work. A simple like-for-like swap usually does not. Check with your local building department before starting any work.
Can a dishwasher be installed in any kitchen?
Most standard kitchens can fit a 24-inch dishwasher. Smaller kitchens can use 18-inch compact models. Very old homes with no existing hookups may need more work before installation is possible.
Are energy-efficient dishwashers actually cheaper to run?
Yes. An Energy Star dishwasher uses about 3 to 4 gallons per cycle versus 10+ gallons in older models. Over a year, that saves real money on water and heating bills, often $35 to $50 annually.
Do stores offer free installation when you buy a dishwasher?
Sometimes. Home Depot and Lowe’s often include free basic installation with purchase during promotions. Always ask at checkout. It’s a legitimate perk that many buyers forget to check before paying separately.
