TL;DR
Repair a dishwasher under about seven years old when the quoted fix is less than half the price of a comparable new machine. Replace it when it is past nine or ten years, when the tub or the pump housing leaks, or when the control board has failed. Most dishwashers last nine to twelve years.
The Verdict: Seven Years and Half the Price
Two numbers do most of the work. If the machine is under seven years old and the repair comes in under half of a comparable replacement, fix it. If it is past nine or ten, replace it unless the fault is genuinely trivial.
Between those ages, the fifty percent rule decides, and it decides against repair more often than people expect because dishwashers are inexpensive relative to their repair labor. That framework is set out fully in the fifty percent rule for repair decisions.
Two faults skip the arithmetic entirely. A leaking tub or a cracked pump housing means replacement, because those are not economically repairable and a slow leak under a dishwasher damages cabinets and flooring long before anyone notices. That is the same structure-versus-part split behind most clean it or replace it decisions on appliances.
What Does a Dishwasher Repair Cost?
Industry Baseline Range
| Fault | Typical industry repair range | Usual verdict |
|---|---|---|
| Diagnostic or service call fee | $75 to $150 | Often credited toward the repair |
| Door latch, gasket, or hinge | $110 to $300 | Repair at almost any age |
| Spray arm or filter assembly | $100 to $250 | Repair at almost any age |
| Drain pump or drain hose | $150 to $400 | Repair at almost any age |
| Inlet valve or float switch | $130 to $350 | Repair at almost any age |
| Heating element | $180 to $400 | Repair under seven years |
| Circulation pump or motor | $300 to $650 | Judgment call, apply the fifty percent rule |
| Main control board | $300 to $700 | Usually replace the machine |
| Tub crack or pump housing leak | $500 to $1,000+ | Replace the machine |
These figures reflect published industry averages. Current market pricing varies significantly and actual quotes may fall well outside these ranges based on site-specific conditions, material costs, and project complexity.
New machines for comparison generally run $400 to $700 for a basic built-in, $700 to $1,300 for a mid-range quiet model, and $1,200 to $2,500+ at the premium end, before installation.
Current Market Reality
Actual quotes land above these baselines more often than below them, and the reason is structural: labor is the dominant cost in dishwasher repair, and a dishwasher has to be pulled out from under a counter and often disconnected from plumbing and electrical to reach almost anything. That is an hour of labor before any diagnosis begins.
Installation on a replacement is the number people forget. Removing the old machine, reconnecting water and drain lines, and hauling the old unit away typically adds $150 to $400, more if the connections are old, if a shutoff valve needs replacing, or if the opening needs adjustment. Countertop and cabinet work turns it into a small remodeling job.
Parts availability also swings the answer. On models more than about eight years old, some boards and pumps are no longer stocked, and a part sourced from a specialist supplier can cost more than the same part did new.

Are the Dishes Not Getting Clean? Check These First
Before any of this becomes a repair question, run four checks that cost nothing. Pull out the bottom rack and clean the filter, which on most modern machines twists out and is the single most common cause of poor results. It should be cleaned monthly and almost nobody does it.
Check the spray arms. Spin them by hand to confirm they turn freely, then hold them up and look for blocked jets, which clear with a toothpick or a straightened paperclip. Then check the water temperature by running the kitchen tap hot before starting a cycle, since most detergents need water at roughly 120 degrees F to work properly.
Finally, check detergent and rinse aid. Old detergent loses effectiveness, and hard water without rinse aid leaves the film people mistake for a broken machine. Running an empty hot cycle with a dishwasher cleaner or with white vinegar in a bowl on the top rack clears scale, though never combine vinegar with a chlorine bleach product, since acid plus bleach releases toxic gas.
When Is Repair Almost Always Right?
Repair when the machine is under seven and the fault is a door latch, a gasket, a spray arm, a filter housing, a drain pump, or an inlet valve. Those parts are inexpensive, accessible, and typically leave the rest of a machine with years of life.
Repair also when replacement carries hidden costs. A panel-ready or integrated machine matched to custom cabinetry is expensive to replace like for like, and an unusual size in an older kitchen may not have a modern equivalent that fits the opening.
And repair when you can do it yourself. Spray arms, filters, racks, and roller wheels are straightforward user-serviceable parts, generally $15 to $80, and replacing a set of worn rack rollers transforms a machine that has become annoying to load. Turn off the power at the breaker and the water at the shutoff before working on it.
When Is Replacing Clearly Better?
Replace when the tub is cracked, when the pump housing leaks, when the control board has failed on an older machine, or when the machine is past ten and needs anything more than a small part. Replace after a second significant failure in a short period, since that pattern rarely reverses.
Replace immediately if the leak has reached the subfloor or a cabinet base. Water under a dishwasher spreads sideways under flooring where you cannot see it, and once framing or subfloor is wet, that becomes water damage restoration work, which is a separate trade from appliance repair.
The efficiency argument is modest but real, since newer machines use noticeably less water and energy per cycle than machines from a decade ago, and quieter operation is a genuine daily improvement in an open-plan kitchen. Neither alone justifies scrapping a working machine, and the same balance applies to repairing or replacing a washing machine.
How Do You Make a Dishwasher Last Longer?
Clean the filter monthly and wipe the door gasket and the lower door lip, where food and grease collect and where most dishwasher odor originates. Scrape plates but do not pre-rinse them thoroughly, because modern detergents need some soil to work against.
Run a maintenance cycle every one to two months with a dishwasher cleaner or with white vinegar to clear scale and grease from the pump and spray arms. In a hard water area, use rinse aid consistently and check whether the machine has a salt reservoir.
Load so that spray arms turn freely, avoid blocking the detergent door with a large item, and run the machine regularly rather than letting it sit unused for weeks, which lets seals dry out. That preventive habit is what keeps small faults from becoming the kind of question raised in when a small appliance repair is worth paying for.
Where Dishwasher Care Fits in a Kitchen Routine
The dishwasher is one of the hidden odor sources in a kitchen, alongside the sink drain, the disposal, the refrigerator drip tray, and the trash can. When a kitchen smells and every visible surface is clean, the filter and the door gasket are the first two places to look.
Beyond that, the surfaces around the machine collect grease that transfers from hands and steam: the cabinet face, the counter edge, and the handle itself. If you are weighing what to keep doing yourself and what to hand off, look at house cleaning services as a whole rather than one appliance at a time.
FAQ
Is it worth repairing a dishwasher?
Usually yes if the machine is under seven years old and the repair costs less than half of a comparable new one. Door latches, gaskets, spray arms, filters, drain pumps, and inlet valves are almost always worth fixing. Control boards, cracked tubs, and leaking pump housings usually are not.
How long does a dishwasher last?
Most dishwashers last nine to twelve years. Hard water, heavy daily use, and skipping filter cleaning all shorten that, while monthly filter cleaning, regular maintenance cycles, and consistent rinse aid use in hard water areas extend it toward the longer end of the range.
How much does a dishwasher repair cost?
Industry ranges generally run $110 to $300 for a door latch or gasket, $150 to $400 for a drain pump, and $180 to $400 for a heating element, with a diagnostic fee of $75 to $150 often credited toward the work. Control boards run $300 to $700.
Why is my dishwasher not cleaning dishes properly?
The most common cause is a clogged filter that has never been cleaned, followed by blocked spray arm jets, water arriving too cool, and old detergent or missing rinse aid. Run those four checks before treating it as a repair, since all of them are free and take about five minutes.
Is it cheaper to repair or replace a dishwasher?
It depends on age and fault. A small part on a machine under seven years old is nearly always cheaper to repair. Past nine or ten years, or with a control board or tub fault, replacement usually wins once you account for installation of $150 to $400 on a new unit.
Should you replace a leaking dishwasher?
Diagnose it first, since a door gasket, a drain hose, or an inlet valve is inexpensive while a cracked tub or a leaking pump housing is not. Act quickly regardless, because water spreads sideways under flooring and a wet subfloor becomes a water damage restoration job.
Check the age, then check the part. Under seven with a small part means fix it; past ten with a leak or a board means order a new one. Every home is different, so the right cleaning plan depends on size, condition, and what you want covered. Get a quote and we will walk you through it.
