Dishwasher: Repair or Replace? Decision Guide

A dishwasher is worth repairing when the fix costs less than half of a new unit and the machine is under about eight years old. Past that, the math tips toward replacement quickly, because the dishwasher has the shortest lifespan of any kitchen appliance. This guide shows you how to run the numbers on your own machine and points you to the year-by-year guides for your exact age.

The quick answer: repair or replace?#

Repair if the quote is under 50% of a new dishwasher and yours is under eight years old. Replace if it is over nine years old and needs a major part like the control board or the circulation pump.

A mid-range dishwasher runs $500-1,300 to replace, so the 50% line sits somewhere around $250-650 depending on what you would buy. Dishwashers last 9-12 years (about 10 on average) — the shortest run of any kitchen appliance. Because the replacement price is on the lower end for a major appliance, the repair threshold is lower too: a $500 repair on a $700 machine is already past the line.

Verdict by age: the dishwasher decision matrix#

Your dishwasher's age against its roughly 10-year lifespan is the first filter. Match your age to your repair size in the table below.

For a read on your exact age, see whether it is worth repairing a 5-year-old, 7-year-old, 10-year-old, 12-year-old, or 15-year-old dishwasher.

What each repair actually costs#

Most dishwasher faults are cheap. Only two are big enough to change the verdict. Here is what the common repairs run, parts and labor together.

Racks, tines, spray arms, and detergent-dispenser doors are minor parts — always worth fixing, no matter the age. They do not touch the machine's core, so they never tip the decision.

The control board vs. pump pivot#

On a dishwasher, the whole repair-or-replace call usually comes down to one of two parts. The control board is the priciest common fault at $250-600; on an older machine, that is roughly half the cost of a new unit, which is exactly where the 50% rule says replace. The circulation or drain pump is more forgiving at $200-400 — still worth doing under nine years, still under half of most new machines.

So when a technician tells you it is the board, slow down and check the age. When it is the pump, a mid-life machine is almost always worth saving. Everything else — a latch, a seal, a heating element — is cheap enough that age barely matters.

The hidden cost: a leaking dishwasher#

A dishwasher is the one kitchen appliance that can cost more than itself when it fails. A leak from a worn door seal or a cracked tub runs under the cabinets and into the floor, and that water damage can add up to far more than a new machine. Do not sit on a leak.

The good news: a door seal is a cheap fix at $100-250, so catching a leak early is both the safe call and the frugal one. The bad news: if the tub itself cracks, the machine's structure is gone and no repair brings it back — that is a clean replace. When you see water on the floor, get it diagnosed before it becomes a flooring bill.

Two worked examples#

Numbers make the rule concrete. Here are two cases in the shapes we see most.

A 4-year-old machine with a failed drain pump. The pump is a $200-400 repair, and the machine is under half of its 9-12-year life. That is under 50% of a new $500-1,300 unit and well under the 80% age line — a clear repair that should return many more years of service.

An 11-year-old machine that needs a control board. The board is $250-600, and at eleven years the machine is already past its expected lifespan. On a $500-1,300 replacement, a $600 board sits right at or over the 50% line, and the age alone points to replace. The money is better spent on a new unit than on a repair that may be followed by the next failure.

When a dishwasher is not worth fixing#

A few situations point straight to replacement, whatever the age. A cracked tub is the clearest: the tub is the body of the machine, and once it leaks at the structure there is no single part to swap. Two or three failures diagnosed at once — say a pump, a board, and a tired door seal together — signal a machine wearing out all over, and fixing one part only delays the next visit. Years of hard water speed that wear along, which is why older machines so often need several small repairs in the same year. And any major repair on a machine past twelve years rarely pays off, because you would be investing in an appliance already living on borrowed time.

What we see in the field#

In our California service area, the dishwasher calls we take most are drains that will not clear and doors that will not latch — both quick, inexpensive fixes. A typical labor charge in our service area runs $150-350, and most dishwasher jobs we finish land between $200 and $600 all-in.

Control boards are the exception. We see them fail more often on machines that have run years of hot cycles on hard water, and by the time the board goes, the racks and seals are usually tired too. When a nine- or ten-year-old machine needs a board and the seals are on their way out, that is the pattern that says the money is better spent on a new unit.

Tariffs and right to repair in 2026#

The 2025-26 landscape tilts the mid-life dishwasher call toward repair. After the 2025 tariffs, appliance prices climbed about 4.3% month over month and parts rose roughly 5-20% — but new machines got more expensive faster than repairs did, which pushes the math repair-ward for a machine still in its prime.

California's SB-244 right-to-repair law helps too. Since it took effect in July 2024, makers of appliances that cost at least $100 must keep parts, tools, and documentation available for at least seven years after the last unit is built. If your dishwasher is a 2017-or-newer model, sourcing the pump or the board is easier and the repair case is stronger.

Frequently Asked Questions#

Is it worth repairing a 10-year-old dishwasher? At 10 years you are past about 80% of the 9-12-year lifespan, so repair only the cheap faults — a $100-250 door or seal, or a $150-300 heating element. A $250-600 control board or a major pump job on a 10-year-old machine usually loses to a $500-1,300 replacement.

What is the average lifespan of a dishwasher? Nine to twelve years, about ten on average — the shortest of any kitchen appliance. Racks and seals tend to age first, which is why older machines often need several small repairs at once.

How much does a dishwasher repair cost? Common faults run $100-400: a door latch or seal is $100-250, a heating element $150-300, and a drain or circulation pump $200-400. The control board is the outlier at $250-600.

When should I replace my dishwasher instead of fixing it? When it is over nine years old and needs a major part, when the tub cracks or leaks at the structure, or when the repair quote tops 50% of a new unit ($500-1,300 mid-range).

Does the 50% rule apply to dishwashers? Yes, and the relatively low replacement price ($500-1,300) makes the threshold lower than for most appliances. A $500 repair on a $700 machine is already over the line.

Are dishwasher parts more expensive after the tariffs? Yes — parts rose roughly 5-20% and appliance prices about 4.3% month over month after the 2025 tariffs. California's SB-244 keeps parts available for at least seven years on 2017-and-newer units, which softens the blow.
