Dishwasher Repair Cost Database

The dishwasher is the appliance people misjudge most often – they replace a fixable one too early, or keep paying for a doomed one too long. The decision is hard because a dishwasher combines cheap, common repairs with a short lifespan of about 9 years and a low replacement price, which pulls the repair-or-replace line closer than on any other major appliance. $300 for a door gasket is far too much. $300 for a control board is a fair price. This page breaks dishwasher repair down to the individual part, puts our own invoice figures next to the national ranges, and shows where the line sits between a fix you can do yourself and one you should not.

Dishwasher Repair Cost by Component

This is the core table. Find the part the technician named and compare their quote to the range. Anything inside the range is normal; anything well above it deserves a second quote.

What Our Own Invoices Show

National ranges describe the whole country. Our figures describe real bills we wrote. Across 64 dishwasher repairs Neighborville priced, the median invoice was $308, and the middle half of jobs – the band between the cheapest quarter and the most expensive quarter – paid $254 to $375. That is a narrow band, and it tells you something useful: most dishwasher repairs are mid-sized jobs, usually one part plus the labor of pulling the machine out of the cabinet to reach it. Dishwashers made up 11.2% of Neighborville’s completed service calls, so this is a steady, everyday repair rather than a rare one.

Our median sits at the top edge of the national $100–$300 band. The national band is a survey average; ours is the complete invoice for each priced repair in our own records, parts and labor together. Put the two side by side and a quote between roughly $250 and $375 for a pump, element, latch or valve job is squarely normal.

What the Most Common Repairs Actually Are

Dishwasher repairs cluster around a handful of parts, and knowing which is which tells you whether you are facing a quick fix or a real decision.

Won’t drain – the #1 repair

A dishwasher that will not drain is the single most common failure and usually points to the drain pump, at $100–$400 installed. The pump itself is often only $20–$100; the rest is labor, because the technician normally has to slide the machine out of the cabinet to reach it. The usual culprit is debris – broken glass, food, a fallen utensil – jamming the impeller. A clogged filter or a kinked or blocked drain hose produces the identical symptom for far less, so a good technician checks those first. Standing water after a cycle is covered step by step in water in the bottom of a dishwasher, and the full drain checklist is in dishwasher not draining.

Leaks – usually the door

A dishwasher that leaks onto the floor is most often the door gasket ($70–$150) or a worn door latch ($90–$250) that lets the door sit slightly open during the wash. Both are low-cost repairs worth doing on almost any unit. A gasket you can see is torn, flattened or crusted with residue is the easy diagnosis; a latch problem tends to show up as a door that needs an extra push to click shut.

Won’t start – check the door first

A dishwasher that will not start often comes down to the door latch. If the door does not register as closed, the cycle will not begin, no matter how many buttons you press. On older machines the float switch ($100–$200) is the next suspect: if it sticks in the raised position, the machine thinks it is already full and refuses to fill. Only after those two are ruled out does the control board come into play.

Dirty or wet dishes – spray arm and heating element

Dishes that come out dirty usually mean a clogged or worn spray arm ($75–$150) or a clogged filter. Dishes that come out clean but wet point to the heating element ($150–$350), a common, moderately priced repair. A failing element also stretches cycle time, because the machine waits for water that never reaches temperature – if your cycles keep getting longer, see how long a dishwasher runs.

Control board – the wild card

A dishwasher that is dead, throws error codes, or has unresponsive buttons points to the control board at $200–$600. On a basic model that is a reasonable repair; on a high-end unit the board alone can pass $750 and approach the price of a new machine. Because a latch or float switch can mimic a dead board, this is the repair where testing before replacing saves the most money.

What the $99 Diagnostic Buys

The diagnostic is the part of the bill that protects the rest of it. For a flat $99, a technician tests the dishwasher instead of guessing, names the failed part, and gives you a firm price before any work starts. When you approve the repair, the $99 is waived, so on a repaired dishwasher you pay for the repair itself. That matters most on the symptoms in the table above that share causes – a no-start that could be a $90 latch or a $600 board, a no-drain that could be a filter or a pump. The most expensive dishwasher repair is the one done on the wrong part.

DIY vs Professional: Where the Line Is

A real share of dishwasher problems can be fixed by a homeowner for the price of the part alone, and knowing the line saves more money than anything else on this page. Labor typically runs $50–$125 per hour nationally and makes up half or more of most repair bills, so the savings on do-it-yourself jobs are real.

Safe to do yourself: cleaning the filter, clearing a clogged drain hose, replacing a worn door gasket ($25–$50 in parts versus $80–$200 professionally), straightening or patching a dish rack with a rack-repair kit, unclogging a spray arm, and reseating a loose hose connection. These are cleanliness and water-flow jobs that need no electrical or plumbing skill.

Leave to a professional: anything involving the control board, the wash or drain motor, the heating element, the inlet valve solenoid, or live wiring. The principle is simple – do-it-yourself maintenance is about cleanliness and flow; professional repair is about mechanics, electricity and safety. A homeowner can clean a filter but cannot safely test heating-element resistance or trace an intermittent solenoid fault.

Cost by Brand and Installation

The same repair costs more on some machines than others, because parts pricing and access differ. Build this into any quote you receive.

Premium brands such as Bosch and Miele cost more per part, and a board or motor on a high-end unit can reach $750 or more – though those brands tend to break less often, which is the trade you are paying for. Bosch in particular accounts for a large share of the dishwashers we service and has its own page: Bosch appliance repair.

Maintenance: The Highest-Return Habit

No appliance rewards maintenance more than the dishwasher, because most of its failures are caused by buildup that maintenance directly prevents. A dishwasher with proper care lasts its full 9 to 12 years and sometimes longer; a neglected one can drop to 6 to 8.

The highest-impact habits are cheap and fast. Clean the filter weekly to keep food debris out of the pump, which prevents the most common failure on the chart. Scrape rather than pre-rinse, since modern soil sensors work better with some residue and pre-rinsing wastes water. Run a descaling cycle regularly – dishwasher-cleaner tablets cost about $20 for a dozen – which is essential anywhere the water is hard. A professional maintenance visit, often around $80, cleans the drain line, filter and spray arms and catches small faults before they become motor or board failures. If your water bill has crept up rather than the machine breaking outright, how much water a dishwasher uses covers the valve and drain faults that quietly raise consumption.

The Regional Difference: Hard Water

No appliance is more sensitive to hard water than the dishwasher, which makes where you live a primary driver of both failure rate and lifespan. Calcium and magnesium scale builds up on the heating element, clogs the spray arm jets and coats the inlet valve, so exactly the failures in the table above arrive earlier and return more often. Hard water can cut a dishwasher’s effective lifespan from about 10 years to roughly 7.

Florida water commonly tests at 8 to 15 grains per gallon, which is hard by any standard, and storm-season power surges add a second risk to the control board. Hard-water markets elsewhere – Chicago, Columbus, Philadelphia, much of Houston – see the same scale pattern. A spray arm or heating element replaced in untreated hard water is on a clock to scale up again, so a softener or regular descaling protects every repair you pay for. More on scale and how to treat it: hard water and your dishwasher.

When a Dishwasher Repair Is No Longer Worth It

Apply the 50% rule against a $600 to $1,700 replacement, but the dishwasher’s short lifespan means the age test matters more here than on any other major appliance. A cheap repair – gasket, spray arm, latch, inlet valve – is worth doing on almost any dishwasher under about 7 years old.

Replacement becomes the better call when a control board ($200–$600, or $750+ on premium brands) or a wash motor ($350–$500) fails on a unit over 7 to 8 years old, when repeated repairs in one year add up to half the price of a new machine, or when hard water has already shortened the machine’s life and the same scale-driven failures keep coming back. Age sets where that line falls year by year, and how long dishwashers last lays it out.
