Dishwasher Repair vs. Replacement: How to Decide
Repair anything minor at $150 to $300, and run the 50 percent rule on major failures against the replacement cost of a comparable machine. A $300 pump repair is a replacement signal on a $500 basic dishwasher and a clear repair on a $1,200 premium one.
Should You Repair or Replace Your Dishwasher?
Repair a dishwasher when the fix costs less than 50 percent of a comparable new unit, and replace it when the fix costs more. Minor failures are worth fixing on any working dishwasher. Major failures need the comparison run against the specific replacement cost, and age moves the answer: under 5 years, repair almost always makes sense, while past 12 years any repair over $150 to $200 is hard to justify.
The 50 Percent Rule
If a repair costs more than 50 percent of what a comparable new appliance would cost, replacement is usually the better value. Treat it as a guideline rather than a hard threshold, and weight age alongside cost. The rule only works if you compare against the specific replacement cost of a comparable dishwasher rather than a category average. (For more on this, see How Much Does Dishwasher Repair Cost?.)
Age Matters as Much as Cost
A major component repair on a two-year-old dishwasher is usually worth making, because most of the service life is still ahead. The same repair on an eight- or ten-year-old unit may buy only a few more years before the next failure. The remaining service life of a 10-year-old dishwasher may be 2 to 4 years, so a repair costing half of replacement is borrowing against remaining life rather than extending it. Past 12 years, any repair over $150 to $200 is hard to justify. Under 5 years, repair almost always makes sense except for severe failures on the least expensive basic units.

Why the Quality Tier Changes the Economics
A basic dishwasher at $400 to $600 new has a different repair threshold than a premium dishwasher at $1,000 to $2,000 new. The same $300 pump repair is 50 to 75 percent of replacement cost on the basic unit, a clear replacement signal, and 15 to 30 percent on the premium unit, a clear repair signal.
Premium machines from Bosch 500 and 800 Series, Miele, and Thermador also have longer design service lives, on the order of 12 to 15+ years, and use higher-quality components. A $350 repair on a $1,200 Bosch is 29 percent of replacement cost, clearly worth doing on a unit under 10 years old.
Dishwasher Repair Cost at a Glance

| Minor repair (door latch, spray arm, gasket, float switch) | $150 to $300 including parts and labor |
| Pump motor | $300 to $650 all-in |
| Control board | $300 to $650 all-in |
| Overall range | $150 to $450, averaging $250 |

Minor repairs at $150 to $300 are worth doing on any functional dishwasher regardless of age or tier, because they are a small fraction of replacement cost on even the cheapest units. Pump motor and control board repairs on a basic dishwasher at $500 new are borderline, and on that same basic unit over 10 years old they tip to replacement. On a premium dishwasher under 8 years old, they are clearly worth it.
What Replacement Actually Costs
| Cost Factor | Typical Range | Notes |
|---|---|---|
| Basic | $400 to $600 | |
| Mid-range | $600 to $1,000 | |
| Premium (Bosch 500/800, Miele) | $1,000 to $2,000 | |
| Built-in panel-ready for custom cabinetry | $1,500 to $3,000+ |
Add installation. A standard replacement that connects to existing water supply and drain lines runs $150 to $300, which adds roughly 15 to 30 percent to the total. Factor it in when you run the comparison: a $500 dishwasher plus $150 installation is a $650 replacement cost, not $500. Before approving a major repair on an older unit, get that number. Knowing whether a comparable new model costs $500 or $1,200 changes how you read a $250 repair quote.
What a New Machine Gives You Beyond Working
When the calculation is genuinely close, the extras matter. A new dishwasher carries a one-year manufacturer warranty covering parts and labor; a repair typically carries only a 30 to 90-day labor warranty from the technician. It meets current energy efficiency standards, which have improved meaningfully over the past decade, so an older unit that is both inefficient and broken strengthens the replacement case. And it resets the service life clock rather than leaving you operating a ten-year-old machine on borrowed time. (For more on this, see Questions to Ask a Dishwasher Repair Technician.)
Two other factors show up in real decisions. Replacement is inconvenient: you have to choose a model, schedule delivery, and deal with removal of the old unit. That inconvenience is real but temporary, and it should not be the reason you authorize a major repair the economics do not support. Conversely, if the current dishwasher never handled your household’s usage volume well, a marginal repair decision is a natural moment to upgrade, since the incremental cost of a more capable model over a basic equivalent is often modest next to the repair you are avoiding.
Getting a Quote You Can Act On
Cost ranges are planning benchmarks, not fixed prices; your actual cost depends on your local labor market, parts pricing, and what the technician confirms on inspection. Get at least two written quotes on equivalent defined scope before committing. Wide variation between quotes usually reflects differences in parts quality, scope completeness, or contractor overhead rather than simple price competition. Verify current general liability insurance and, for any work with employees on your property, workers compensation coverage; licensing requirements vary by state and trade. Get scope in writing, including parts, labor, timeline, disposal of the old unit, and warranty terms. For any project over $500, written scope is non-negotiable, and a contractor who demands full payment upfront before work begins is a red flag in any trade.
Frequently Asked Questions
Repair minor failures such as a door latch, gasket, or spray arm on any working unit. For major repairs, apply the 50 percent rule against the replacement cost of a comparable machine: a premium Bosch or Miele at $1,000 or more justifies significant repair investment, while a basic $500 unit does not.
Over 10 years, a major component repair requires the replacement comparison, since remaining service life may be only 2 to 4 years. Over 12 years, any repair above $150 to $200 is hard to justify. Under 5 years, repair almost always makes sense.
If the repair cost exceeds 50 percent of what a comparable new appliance would cost, replacement is usually the better long-term value. It is a guideline rather than a hard rule, and age should be weighted alongside cost.
Basic units run $400 to $600, mid-range $600 to $1,000, and premium models such as Bosch 500/800 and Miele $1,000 to $2,000. Built-in panel-ready models for custom cabinetry run $1,500 to $3,000 or more.
Yes, more strongly than a basic unit. Premium machines cost $1,000 to $2,000 new and have design service lives of 12 to 15+ years, so a $350 repair on a $1,200 Bosch is 29 percent of replacement cost and clearly worth it on a unit under 10 years old.
Yes, modestly. Standard replacement installation onto existing water supply and drain lines runs $100 to $200, adding 10 to 20 percent to the total. A $500 dishwasher plus $150 installation is a $650 replacement cost, which is the number to compare a repair quote against.
Yes. New appliances typically carry a one-year manufacturer warranty covering parts and labor, with extended options available. A repair usually carries only a 30 to 90-day labor warranty from the technician.
It can be. Dishwashers built a decade or more ago are often less efficient than current models, so an older unit that is running inefficiently and needs a major repair has a stronger replacement case than the repair quote alone suggests.
