Decision guide
Repair or replace a dishwasher
A dishwasher reaches this decision early, and the arithmetic on this page is why. It is expected to last several years less than the refrigerator and the range it sits between, it carries a moderate replacement price, and it has two faults — the circulation pump and the control board — that both land close to half of what a new one costs before age is accounted for at all.

Two numbers, and they are not the same number
Every repair-or-replace answer is one of two tests. One is fixed against the price of a new unit and never moves. The other falls every year you own the appliance.
The fixed rule
$350
Half the price of a new dishwasher
If the repair quote is more than half the price of an equivalent new unit, replacement is usually the better spend. Below half, repair almost always wins on cost per remaining year of service.
Of the 8 dishwasher repairs priced below, 6 fall entirely under this line, 2 straddle it and 0 sit entirely above it.
The rule that moves
$61
Half of what a 10-year-old one is worth
The stricter version is to spend no more than half of what the appliance is worth today, which is the ceiling the value estimator returns. At age zero the two rules give exactly the same number, because a brand-new unit is worth what a new unit costs. Every year after that they diverge: the price of a replacement stays where it is while the value of yours falls.
A dishwasher sits on this site's fast depreciation curve, so the ceiling falls from $350 when new to $147 at 5 years and $61 at 10.
Then check the age against expected lifespan. An appliance past roughly three-quarters of its expected life has little runway left to earn back a large repair, so the threshold drops as the machine gets older — on an old unit, a repair at a third of new price can still be the wrong call.
Every dishwasher repair, judged both ways
8 priced dishwasher repairs, from filter, sump, and spray-arm clean-out at $80–$160 up to electronic control board at $250–$500. The last column is the last whole year at which the typical quote for that job still sits under the ceiling.
| Repair | Typical quote | vs $350 | Pays back through |
|---|---|---|---|
| Filter, sump, and spray-arm clean-out | $80–$160 | Under | Year 6 |
| Door gasket replacement | $130–$260 | Under | Year 3 |
| Drain pump | $150–$300 | Under | Year 2 |
| Water inlet valve | $150–$300 | Under | Year 2 |
| Door latch or lock assembly | $130–$280 | Under | Year 3 |
| Heating element | $180–$350 | Under | Year 1 |
| Circulation / wash pump | $250–$450 | Straddles | New only |
| Electronic control board | $250–$500 | Straddles | Never |
"Under" is a band wholly below $350, led here by filter, sump, and spray-arm clean-out. "Straddles" is a band that crosses it, so where your quote lands inside them is the decision — circulation / wash pump and electronic control board. "Over" means the cheapest version of the job already exceeds the line, which nothing on this appliance does. The pays-back column applies the stricter test to the midpoint of each band. None of this includes the diagnostic fee, which is charged for the visit and the diagnosis whether the verdict is good or bad. Many shops credit it against the repair if you approve the work the same day and many do not, so ask before the van is dispatched rather than after.
What makes this decision different on a dishwasher
The method is the same on every appliance. What is not the same is which faults are expensive, what replacement actually involves, and how long the machine has left to earn a repair back.
Two features of this appliance compress the timeline. It is on the fast depreciation curve, so its value falls more steeply each year than a refrigerator's or a range's does, and it is not expected to last as long as either of them. Together those mean the ceiling drops early and drops fast. The other distinctive thing is that a genuine share of poor-cleaning complaints are not faults: a clogged filter, a blocked spray arm or hard-water scale is a clean-out, and it is worth ruling out before you price anything.
Repair wins
Water-path and door faults in the first half of its life
Filters, spray arms, gaskets, latches, drain pumps and inlet valves are the affordable majority of dishwasher work and they clear the thresholds comfortably on a machine that is not yet old. The latch is worth singling out: a dishwasher that will not start reads as a dead control board, and the switch inside the latch is a fraction of that price.
Replacement wins
The circulation pump or the control board on a machine past seven
These are the two expensive parts on the appliance and both land near the replace threshold on their own. On a machine that has already used most of its expected life, the money buys very few remaining years. A cracked tub or racks that have rusted through and are shedding onto dishes are replace cases at any age, because neither has a repair.
The argument nobody makes for you
What breaks next on a dishwasher
The pattern here is scale and heat. Hard water deposits load the circulation pump and the heating element together, so a machine that has just had one of them replaced has the other working under the same conditions that killed the first. Racks and the door gasket age on the same clock. This is why a second dishwasher repair inside two years is usually the moment to stop.
What a dishwasher is worth, and what that buys
Five points across a 10-year expected life, on the fast depreciation curve this site assigns a dishwasher. Value is what the estimator returns for a mainstream unit of that age, the ceiling is half of it, and the last column counts how many of the 8 priced dishwasher repairs still sit under it.
| Age | Estimated value | Repair ceiling | Model verdict | Repairs still clearing |
|---|---|---|---|---|
| 1 yr | $588 | $294 | Repair | 6 of 8 |
| 3 yr | $415 | $208 | Repair | 3 of 8 |
| 5 yr | $293 | $147 | Repair | 1 of 8 |
| 8 yr | $174 | $87 | Borderline | 0 of 8 |
| 10 yr | $122 | $61 | Replace | 0 of 8 |
How to read this
Every ceiling on this page is half the value the estimator gives a unit of that age in excellent condition. Excellent is deliberately the generous end of the model — it values the appliance as it will be once the fault is fixed, which is what the repair is actually buying. Rate your own unit honestly in the estimator and every figure here moves down.
Where the verdict flips
The model stops recommending repair outright at year 7 and starts recommending replacement at year 9. The $50–$100 diagnostic fee stays a small fraction of that ceiling across the whole of this appliance's expected life, which is one reason a dishwasher is worth diagnosing properly rather than guessing at.
What the brand does to the line
Brand does exactly one thing in this model: it moves the price of a comparable new unit, which moves the threshold with it. It does not change the expected life of a dishwasher and it does not change the depreciation rate.
| Price tier | Multiplier | New unit | Replace above | Dearest repair |
|---|---|---|---|---|
| Budget | ×0.70 | $490 | $245 | Over |
| Mid-range | ×1.00 | $700 | $350 | Straddles |
| Premium | ×1.50 | $1,050 | $525 | Under |
| Luxury | ×2.20 | $1,540 | $770 | Under |
The last column takes the dearest dishwasher repair priced on this site — electronic control board at $250–$500 — and asks where it lands against each tier's threshold. Tiers are typical retail positioning applied uniformly across every appliance type by this site's value model; not every tier is well represented in every category, and a brand the model does not recognise is treated as mid-range. This is also the reason a built-in or premium dishwasher is worth repairing at prices that would total a mainstream one — the appliance you are being compared against costs more.
What replacing a dishwasher costs that the sticker does not
Every threshold on this page is built from $700 for the appliance. Getting a dishwasher out and a new one in is not included in that, and on this appliance it is plumbing and electrical connection that does most of the damage to the estimate.
A dishwasher is plumbed, wired and screwed to the countertop, so replacing one is genuinely an installation rather than a delivery. Water and drain connections have to be made, the electrical connection has to be terminated properly, and the machine has to slide into an opening that was often cut before the current floor was laid. Panel-ready and integrated fronts add the cabinet panel to the job.
- Plumbing and electrical connection
- Supply, drain and a terminated electrical connection, none of which come with the appliance.
- Fitting the existing opening
- A floor laid after the original install routinely means the old machine will not come out without persuasion.
- Custom or integrated panels
- A cabinet front has to be removed from the old machine and fitted to the new one.
Replace a dishwasher when
- The wash pump or control board has failed on a machine past year seven.
- The quote exceeds roughly $350 — half the price of a mainstream new unit.
- The tub is cracked, or the racks have rusted through and are shedding onto dishes.
- It leaks from under the tub and the cabinet floor is already water-damaged.
When it stops being a cost decision
A machine leaking from under the tub into a cabinet floor is doing damage that costs more than the appliance, and the water damage does not pause while you weigh a quote. That one comes out of service first and gets decided afterwards.
Three things override the arithmetic entirely. Safety is not a cost decision: an appliance that is a fire, gas, water or electrical hazard comes out of service regardless of what a repair would cost. A part that is discontinued ends the conversation whatever the quote was going to be. And a second failure on the same machine inside a year is telling you about the rest of the components, not about the one that just broke.
The question that settles it
Everything above is arithmetic on a typical dishwasher. One answer about your own appliance narrows it faster than any of it, it costs nothing to establish on the phone, and it is worth having before you commit to the $50–$100 diagnostic fee.
Ask this first
Ask whether the machine fills and whether there is an audible wash during the cycle. Fills and washes but cleans badly points at a clean-out or a spray-arm problem — the cheap end. Fills but runs silently through a full cycle points at the circulation pump, which is the fault that decides this question.
Then ask for a written estimate with parts and labour as separate lines, and hold the total against two numbers: $350, and the ceiling for your dishwasher's actual age — $147 at 5 years, $61 at 10. A quote between the two is where the decision is genuinely yours, and it is worth doing on a machine you have looked after and worth walking away from on one you have not.
Nothing here has seen your dishwasher, and nothing here is a quote. What this page can do is tell you which answers move the number — whether the fault is electronic control board or something a quarter of the price, before you pay anyone to look.
