Should You Repair or Replace Your Dishwasher? (Honest Guide)
We get asked this daily across Washington, and here's our policy: we'll tell you when replacement is the smarter move — even though we make money on repairs. A shop that only ever says "repair it" is selling, not advising. Here's the exact framework A One Dishwasher Repair WA uses. Not sure where your machine stands? Call (253) 549-3002.
If the repair costs less than 50% of a comparable new dishwasher, repair it. If more, replace it.

The 50% Rule
Example: your 6-year-old Bosch needs a $280 drain pump. A comparable new Bosch is $900+. $280 < $450 (50%) → repair, obviously.
Counter-example: your 11-year-old budget unit needs a $380 control board. A comparable new one is $550. $380 > $275 → replace.
Lifespan by Brand (Realistic Numbers)
| Brand | Typical lifespan | Repair sweet spot |
|---|---|---|
| Bosch | 10–12 years | Worth repairing under 9 |
| KitchenAid | 8–10 years | Worth repairing under 7 |
| Whirlpool / Maytag | 9–11 years | Worth repairing under 8 |
| Samsung / LG | 7–9 years | Worth repairing under 6 |
| GE | 8–10 years | Worth repairing under 7 |
| Frigidaire | 7–9 years | Worth repairing under 6 |
Under the "sweet spot" age + under 50% cost = repair every time. Over on both = replace.
5 Signs It's Time to Replace
- Rust inside the tub — structural, not fixable economically
- 3+ repairs in 2 years — it's telling you it's done
- Repair quote over 50% of new (see above)
- It's 12+ years old with any major failure — even a "cheap" fix is throwing good money
- Parts discontinued — rare under 10 years, common past 12
3 Signs You Should Definitely Repair
- It's under 5 years old — almost always worth fixing, whatever the part
- It's a premium brand (Bosch 800, KitchenAid, Miele) — the tub and racks alone justify repair
- Single simple failure (pump, latch, valve) on an otherwise healthy machine
The Hidden Cost of Replacing
A new dishwasher isn't just the sticker price: delivery ($50–$100), installation ($150–$250), haul-away ($30–$75), and possibly plumbing/electrical updates in older Washington homes. A $600 dishwasher is really an $850–$1,000 project. Factor that into your 50% math. If replacement wins, our installation service covers delivery setup and haul-away.

Repair vs. Replace FAQs
My dishwasher is 10 years old and needs a $200 pump — repair?
Probably yes — $200 is well under 50% of new, and a pump doesn't predict other failures.
Is it worth repairing a Samsung with a bad control board at 7 years?
Borderline. Board + labor can hit $400+ on a machine with a 7–9 year lifespan. We'd show you both options honestly.
