Dishwasher Repair vs Replace: What Each Really Costs (And How Long They Last)
Your dishwasher has stopped working, and the real question isn’t “can it be fixed?” It’s “should it be?” A repair that costs more than the machine is worth is money wasted — and a machine binned over a ten-dollar part is a waste too.
This hub applies the general framework to dishwashers specifically. For the framework itself — the five rules, the lifespan data, and the decision flowchart that works on any appliance — see Should I Repair or Replace It? The Complete Decision Framework.
But here’s the problem with almost every repair-or-replace calculator you’ll find: it compares the repair cost to the replacement cost, and leaves out the number that actually decides it. The call-out fee.
A repairer typically charges $65–$165 just to turn up and diagnose, often before a cent of parts or labour. That fee changes the maths on every small repair. A $150 fix becomes a $250–$300 decision once the diagnostic charge is on the bill. And that’s the point at which people start saying “it’s not worth fixing” — not because the part was expensive, but because the visit was.
This guide gives you the rule we use at Repair or Bin, the sourced costs on each side, and a verdict for the most common faults. All figures are US dollars; adjust for your region.

The short verdict
Repair it if the fix costs less than about half the price of a comparable new machine, and the dishwasher is still within its normal lifespan.
That’s the 50% rule, and it’s the standard framework appliance technicians use. It works because it’s conservative — it leaves room for the thing you can’t predict, which is whether the next fault is three months away.
The lifespan part matters just as much as the cost part. Most dishwashers last around 10 years according to Consumer Reports, and the Association of Home Appliance Manufacturers puts the average at about 12 years. Once a machine is past that, a repair isn’t just a cost decision — it’s a bet against the next failure.
So the two-question test is:
Repair it when the fault is a blockage, a seal, a pump, or a heating element, and the machine is under about 10 years old.
Bin it when the repair is over half the replacement price, when the control board has failed on an older machine, or when it’s failed more than once in a few years.
What repairs and replacements actually cost
This is the table to check your quote against. “Installed” means a professional doing the work, including labour.
Fault Typical installed cost DIY part cost Our verdict
Blocked filter or drain hose $50–$400 (often $0 if DIY) $0–$30 Repair — usually free
Failed drain pump $150–$450 $20–$150 Repair, unless the machine is near end of life
Worn door seal (gasket) $50–$300 $10–$90 Repair — cheapest fix on the list
Failed heating element $150–$350 $25–$75 Repair on a machine under ~8 years
Failed control board $180–$585 $60–$230 Usually bin on an older machine
New dishwasher, installed $400–$1,500 (typical ~$1,000–$1,200) — The benchmark for the 50% rule
Sources: general repair range $70–$600, most homeowners $160–$300, average ~$200. Drain pump $150–$450, most commonly $150–$300. Door seal $50–$300, typically $100–$250. Heating element $150–$350. Control board $180–$585 installed. Replacement: machine alone $500–$2,000, total installed $1,000–$1,500, with budget installations reported as low as $400–$1,200.
Read the control board line twice. That’s the one fault where the honest answer is usually “don’t.” A board at $180–$585 installed against a machine that’s eight years old and worth maybe $300 used fails the 50% rule by a wide margin. Everything else on this list usually passes it.
How long do dishwashers last?
Most dishwashers last around 10 years. Consumer Reports puts the average at about a decade, and CR’s surveyed members expected the same. AHAM’s figure is closer to 12. The honest range is 9–13 years for most machines, with real variation by brand and water hardness.
Brand matters more than most buying guides admit:
Brand Typical lifespan Notes
Bosch 10–15 years (Bosch itself says 6–16) Owners frequently report 18–20 years; among the lowest repair rates in the first five years
KitchenAid 10–14 years Premium tier, longer service life
GE 9–14 years Mid-range; parts widely stocked
Whirlpool / Maytag / Amana 9–12 years Inexpensive parts keep repair sensible past year ten
LG / Samsung 8–13 years Electronics-heavy; boards are the weak point after year eight
Frigidaire 8–12 years Shorter end of the mid-range
Miele 20-year design life Lowest failure rate in reliability rankings
Two things follow from that table. First, a Bosch at year eight is a different proposition from a Frigidaire at year eight — the Bosch has years left, the Frigidaire is near its expected end. Second, the brand changes the repair quote too: HomeAdvisor’s data puts typical repair costs at $50–$450 for Bosch and $50–$600 for LG and KitchenAid.
Fault by fault: repair or bin?
Dishwasher not draining, or standing water in the bottom
Verdict: usually repair. Water left in the bottom is more often a blockage in the filter, drain hose or pump than a dead machine — and a blocked filter costs nothing to clear. That keeps the repair well under the 50% line.
Start with our Dishwasher Not Draining guide. If it’s a Bosch and there’s a code on the display, the fault code narrows it down further — see the E24 guide and the E25 guide, or the full Bosch Dishwasher guide.
Bosch E15 fault code
Verdict: check before you bin. E15 is a flood-safety code — water in the base tray has tripped the float switch. It is not a control board failure, and it is not a sign the machine is finished. The fix is often finding and clearing a leak, not replacing a component.
Our Bosch E15 guide covers what to check first, in order.
Dishes not coming out clean
Verdict: check before you repair. This is usually maintenance or loading before it’s a repair — a clogged filter, blocked spray arm jets, or an overloaded rack. All free to fix.
Work through the Dishwasher Not Cleaning Dishes guide before you spend anything.
Leaking from the door
Verdict: usually repair. A worn door gasket is one of the cheapest fixes on any appliance — $50–$300 installed, and $10–$90 for the part if you fit it yourself. Against a $1,000 replacement, this fails to reach the 50% line even on a fairly old machine.
And not every door leak is the gasket: a dropped hinge or a worn latch produces the same symptom with a perfectly good seal, and those fixes cost nothing.

No heat, or dishes not drying
Verdict: repair on a younger machine. A failed heating element runs $150–$350 installed, with the part at $25–$75. On a machine under eight years old that’s comfortably a repair. Past ten years, the lifespan question starts to weigh as heavily as the cost.
But check the water supply before testing any component — a cold fill or a closed valve produces the same symptom for free. And be aware that the high-limit thermostat, not the element, is the most commonly misdiagnosed part in this circuit.

Control board failure
Verdict: often bin on an older machine. A control board runs $180–$585 installed. On a machine that’s eight-plus years old, that’s at or over the 50% line — and it’s the fault most likely to be followed by another.
Before you accept that verdict, confirm the board really is the problem. The brand guides help: Whirlpool, GE, Samsung, and LG fault diagnosis guides all cover board-level diagnosis.
When replacing is the better choice
The quote is more than about half the price of a comparable new machine — the 50% rule, applied to the actual number, not the estimate.
The machine is at or past its expected lifespan. Around 10 years for most brands; sooner for Frigidaire, later for Bosch and Miele.
It’s needed more than one repair in the last few years. Repeat faults are the strongest signal that the machine is on its way out.
The fault is the control board and the machine is older. This is the one component where repair rarely wins.
The replacement would be meaningfully more efficient or quieter. A 12-year-old machine against a current model can pay back part of its cost in water and energy.
FAQ
Is it worth fixing a 10-year-old dishwasher?
Depends entirely on the fault. A blocked filter, a door seal or a drain pump on a 10-year-old machine can still be worth fixing — those repairs are $50–$450 and sit well under the 50% line. A control board at $180–$585 on a 10-year-old machine usually isn’t. Ten years is the average lifespan, so the machine has no margin left, but it isn’t automatically finished either.
How much does it cost to fix a dishwasher?
$70–$600, with most homeowners paying $160–$300 and the average around $200. The fault decides where in that range you land: a seal is at the bottom, a control board or motor at the top.
Why do repair quotes seem higher than the prices online?
Because the online price is the part, not the job. Add $65–$165 for the call-out and diagnosis, plus labour, and a $60 part becomes a $250 repair. That’s not a rip-off — it’s the cost of someone driving to your house and identifying the fault. But it’s why the 50% rule has to be applied to the quote, not the part price.
Can I fix it myself?
Many of the common faults, yes. Filter blockages, door seals, and on some machines the drain pump are genuinely DIY-able, and the part costs are a fraction of the installed price. The ones to leave alone are anything involving the control board or the mains wiring.
Should I repair a dishwasher that’s still under warranty?
No — use the warranty. Don’t open the machine yourself, because that can void it.
