Bosch Dishwasher Control Board Cost: Repair or Buy New?
A tech quoted a control board for a 7-year-old Bosch dishwasher. How the purchase date, the repair shop and two rules of thumb weigh your quote.

The short version: “Control module replacement — part $230 / labor & trip $170 — total $400.” That’s the technician’s line, and the order email for the Bosch says it was bought seven years ago. Bosch’s coverage for a control board ends on the fifth anniversary of the purchase, so at year seven the whole ticket is yours.
Why it matters: Whether it’s worth paying depends on what you hold it up against. Next to a new dishwasher at $1,175 installed, it’s about a third. Next to what a $1,000 machine is still worth after seven years at 10% a year, the yardstick in a 2022 Consumer Reports article, it’s more than the machine.
Bosch counts a dishwasher’s warranty from the date of the original purchase, and the warranty statement in the manual says that clock “shall not be stalled, tolled, extended, or suspended, for any reason whatsoever.” It runs whether or not the registration card ever went back.
Bosch’s US warranty page lists two dishwasher tiers that matter here. The first year covers the entire appliance, parts and labor. From the 2nd through the 5th year it covers “electronics (microprocessor or printed circuit board); parts only,” which is the board on the ticket without the labor.

Find the year on the order email, then the column it lands in.
Read against this ticket, that’s nothing in the first year, the $170 of labor and trip in years two through five, and every line after that.
The moneyWhat the Board Costs Next to a New Dishwasher
There are two published ways to weigh a repair bill like this one, and they don’t use the same yardstick.
Angi’s version of the 50% rule says to replace when the repair costs 50% or more of a replacement appliance, and to count the installation in that price. Say the dishwasher you’d buy instead is $1,000 and the install is the $175 Angi uses in its own example. The ticket comes to 34% of $1,175, under the line, so this rule says repair.
Consumer Reports’ 2022 article starts from the old machine instead. Manufacturers told CR they design dishwashers to last about ten years, so CR estimated they lose 10% of their purchase price every year. Under 33% of the value that’s left, repair. From 33% to 49%, think about replacing. At 50% or more, replace. A $1,000 Bosch at seven years has $300 of value left, and the ticket is 133% of it.

One ticket and two yardsticks, on the same seven-year-old Bosch.
I didn’t see the two rules disagree until I set them side by side on the same seven-year-old machine. Each reads like plain sense on its own page. One asks what the alternative costs, the other asks how much machine the money is keeping alive, and past the middle of a dishwasher’s life those answers drift apart.
CR’s current page, updated in January 2024, no longer prints the 10%, 33% and 50% figures. It runs an interactive tool instead and says that for dishwashers the data “typically leans toward replacement,” so the lines used here belong to the 2022 article.
The calculator splits your own ticket by Bosch’s clock, then runs what’s left through both rules.

You pay = the quote minus what Bosch covers. Through a Bosch-authorized provider, Bosch covers the whole quote in the first year from purchase and the board part in the 2nd to 5th year, and nothing after the 5th anniversary. 50% rule (Angi): what you pay against a new dishwasher plus installation, 50% or more means replace. Consumer Reports' 2022 rule: what you pay against the purchase price minus 10% a year, under 33% repair, 33% to 49% think it over, 50% or more replace.

Years two to fiveInside Five Years, Who Puts In the Board Changes the Ticket
The warranty statement limits Bosch’s liability to repairs made “using a Bosch-authorized service provider,” and says Bosch has no responsibility for work done by a non-authorized one. In years two through five, the free board comes through a Bosch-authorized service provider.
The fifth anniversary is a hard edge. A day before it, the board is Bosch’s and the ticket shrinks to labor and trip. A day after, it’s the whole thing. A board replaced under the warranty doesn’t start a new five years either, because the statement gives a replaced part “the identity of the original part.”
Two questions get the calculator the numbers it needs, whatever year the machine is in.
“Can you split this quote into the board part and the labor and trip charge? And are you a Bosch-authorized service provider?”
A board that failed from a power surge or lightning is on Bosch’s exclusion list, so it can be refused even inside year five. Older Bosch manuals start the term at installation rather than purchase, and the statement in your own manual is the one that counts. If you hold a Bosch service plan, a credit-card extended warranty or a home warranty, that contract decides the board before any of this does.
The order email is usually easier to find than the manual. If it puts the machine in its 2nd through 5th year and the tech who diagnosed the board isn’t Bosch-authorized, then the $230 part on that ticket is one Bosch would have supplied through an authorized provider, leaving only the labor and trip.
