Should You Repair or Replace a Dishwasher?

Dishwashers sit in an interesting spot: they're affordable to replace but full of repairable parts. That means the repair-or-replace decision often comes down to age and the specific component that failed. This guide gives you the 50% rule for dishwashers, the real cost of common repairs, and a clear way to decide whether to call a tech or shop for a new unit.

The 50% rule for dishwashers

Apply the 50% rule: if a repair costs more than half the price of a comparable new dishwasher, replace it. A solid new mid-range dishwasher runs about $500–$900, so a repair quote above $250–$450 crosses into replacement territory — especially on an older machine.

Add the age rule: dishwashers typically last 9–10 years, a shorter lifespan than most kitchen appliances. A major repair on a 9- or 10-year-old dishwasher rarely makes sense.

💡 Built-in vs portable: Built-in dishwashers add installation/uninstallation labor to replacement, which slightly raises the bar for replacing. Even so, dishwashers are cheap enough that the 50% line arrives quickly compared with refrigerators or ranges.

Typical dishwasher repair costs

Here's what common dishwasher repairs run in 2026, including parts and labor.

When repair is the smart choice

Repair usually wins when:

• The dishwasher is under 7–8 years old. It's mid-life with plenty of service left.
• It's a small, common fix — door latch, spray arm, inlet valve, gasket, or drain pump. These are inexpensive and fully restore function.
• The repair is well under half the price of a new unit.
• It's a high-end model (Bosch, Miele, KitchenAid premium) where replacement runs $900–$1,500+, making a moderate repair worthwhile.
• Only one component has failed and the tub, racks, and door are in good shape.

When replacement makes more sense

Lean toward a new dishwasher when:

• It's 9+ years old and facing a repair over $250–$300.
• The circulation pump motor or control board has failed on an older unit — these repairs ($250–$450) often exceed half the cost of a new machine.
• It leaks from the tub or sump (not just a gasket), risking cabinet and floor damage.
• It's been repaired before or has multiple issues at once.
• Cleaning performance has declined despite cleaning the filter and spray arms — a sign of a worn pump or motor.

⚠️ Try maintenance first: Many "broken" dishwashers just need a clean. A clogged filter, blocked spray-arm holes, or a backed-up drain hose causes poor cleaning and drainage that mimics a failure. Clean the filter, clear the spray arms, and check the drain before paying for a diagnosis. See our error-code guides for codes like Bosch E15 and Whirlpool F2 E2.

The control board and pump question

Two failures most often push a dishwasher into replacement territory: the control board / user interface ($200–$400) and the circulation pump motor ($250–$450). On a dishwasher that's 9+ years old, either repair frequently lands at or above half the price of a new unit — and once one major part fails, others tend to follow. For a newer dishwasher, though, both repairs are usually worth doing.

Factor in water and energy efficiency

Modern dishwashers are markedly more efficient than models from the early 2010s, using less water per cycle and less energy to heat it. An ENERGY STAR dishwasher can save water and power over its lifetime versus an aging unit. As with other appliances, that won't justify replacing a working machine, but it adds weight to the replace side when a costly repair is already on the table.

A simple decision framework

1. Is it under warranty? Repair — you may owe only labor.
2. Is it under 7–8 years old with a sub-$250 repair? Repair.
3. Is it 9+ years old facing a $300+ repair, or is the pump motor/control board the issue? Replace.
4. In the gray zone? Apply the 50% rule and add efficiency savings to the replace side.
5. Is it a premium model? Bias toward repair — replacement is more expensive.

Does a home warranty change the math?

Yes. Built-in dishwashers are commonly covered on home warranty appliance plans. A qualifying breakdown — control board, pump, motor, valve — means you pay only your service call fee, up to the plan's cap, instead of the full repair. That can make repairing an older dishwasher worthwhile. Just note that cosmetic issues and maintenance (like a clogged filter) aren't covered, and any water damage from a leak falls under homeowners insurance, not the warranty.

Frequently asked questions

Is it worth repairing a dishwasher that won't drain? Usually yes — a no-drain is often a clogged filter, blocked drain hose, or an inexpensive drain pump. Clean the filter and hose first; if it's the pump, the repair is still affordable on a newer unit.

What is the most expensive dishwasher repair? The circulation (wash) pump motor or the control board, at $250–$450. On an older dishwasher, either can justify replacement.

How long does a dishwasher last? Typically 9–10 years — shorter than most kitchen appliances — which is why the replace threshold comes relatively early.

Why isn't my dishwasher cleaning well? Most often a clogged filter, blocked spray-arm holes, hard-water buildup, or a worn wash pump. Cleaning fixes the first three; a worn pump is a repair.

Does a home warranty cover dishwasher repairs? Yes, built-in dishwashers are commonly covered. A covered breakdown means you pay just the service fee up to the plan cap.

The bottom line

Because new dishwashers are relatively cheap and the typical lifespan is only 9–10 years, the repair-or-replace line arrives sooner than with other appliances. Fix the small stuff — latches, spray arms, valves, gaskets — especially under 8 years old. But a failed pump motor or control board on a 9+ year-old machine usually means it's time to replace. Always clean the filter and spray arms first; many "failures" disappear with a good cleaning.
