What Drives the Price Up or Down
- Brand: Frigidaire/Whirlpool parts are cheapest; Bosch/Miele parts cost more (but the machines last longer, so the math still works).
- Age: 10+ year-old units sometimes need two things at once — we'll tell you if the combined cost doesn't make sense.
- Access: Built-in units in tight custom cabinetry take longer. Standard installs are fastest.
Repair vs. Replace: The 50% Rule
Repair if: the fix costs less than 50% of a comparable new dishwasher AND the unit is under 8–10 years old.
Replace if: the repair exceeds 50%, the tub is rusted through, or it's had 3+ repairs in two years.
Gray zone: 8–10 years old with a mid-range repair — we'll give you both numbers and an honest recommendation. And yes, we install replacements too. See the full repair vs. replace guide.
Red Flags: When a Quote Is a Ripoff
- Diagnostic fee NOT waived with repair (industry standard is waived)
- "You need a new control board" without any testing
- Pressure to decide on the spot
- No written warranty
