What affects the price
Replacement vs first install
Swapping an old dishwasher is quick since the water supply, drain, and power are in place. A brand-new spot needs all three run, which is far more work.
Electrical hook-up
Some dishwashers plug into an outlet, others are hardwired. Adding a dedicated outlet or circuit may require an electrician on top of the plumber.
Cabinet fit
If the opening is not a standard 24 inches, cabinets may need trimming or a filler panel, adding time and sometimes a carpenter.

Can a handyman install a dishwasher, or do I need a plumber?
A straight replacement is often done by a handyman or appliance installer. New plumbing or electrical connections are better handled by a licensed plumber or electrician.
Does the dishwasher price include installation?
Rarely. Retailers often charge a separate install fee ($150–$250), and haul-away of the old unit may cost extra too.
