What Year Is My Dishwasher? Here’s How to Tell!

If you recently moved into a house with a dishwasher included, determining what year it’s from is not a bad idea.

Having this information will tell you how many years you should have left with that dishwasher.

How do you find the age of your dishwasher? We researched this topic to find the answer for you!

To determine what year your dishwasher is from, look at the serial number.

The serial number usually has a mix of letters and numbers, sometimes just numbers.

Once you know how to read it, you can figure out the year, month, or even the week the dishwasher was crafted.

In this article, we’ll explain in more detail how to ascertain the year of your dishwasher.

We’ll also delve into the average lifespan of a dishwasher, how to maintain yours, and if you should fix versus replace it.

How Do You Know What Year Your Dishwasher Is From? Here’s How to be Sure

Going back to the scenario we mentioned, if the dishwasher was there when you moved in, you wouldn't know if it's two or twelve years old.

The serial number will reveal the information you’re looking for.

The serial number will have a series of letters and digits or just digits with an indication "serial," "serial no," or just "S/N."

Below we've listed a few dishwasher brands and how you can figure out the manufacturing date through the serial number.


For Bosh dishwashers, the serial number usually starts with 'FD,' and the following four numbers often represent the production year and month.

You can find this next to the model number.

Don't be confused with the longer version of the serial number on the lower part of the label. We'll only need the first four digits, after all!

For example, 'FD9610' might indicate the product was made in October 2016. Here's how we figured that one out!

  1. Take the first two digits and add 20. So, 96 + 20 = 116. Consider only the last two digits. In this case, you get '16' or 2016.
  2. The remaining two digits in the four-digit sequence represent the month. With "10", that’s a clear sign of an October production.


To determine the production date of your GE dishwasher using the serial number, you'll want to focus on the first two letters in the serial number.

The chart provided here can help you translate these letters into specific months and years.

A serial number starting with, for instance, "RL" could indicate that your dishwasher was manufactured in either August of 2018 or August of 2006.

Please know that the second letter, which corresponds to the year, changes roughly every 12 years.

If you get confused with multiple potential years, you can refer to your dishwasher's owner's manual for additional guidance.

They can include a publication date, often found on the front or back page.


In Frigidaire's serial numbers, the third character represents the year of manufacture.

Take, for example, the serial number NF11910958.

  • The "NF" at the beginning typically indicates where the appliance was made.
  • The first digit of the serial number represents the year of manufacture. In this case, "1" signifies the year 2001.
  • The fourth and fifth characters in the serial number indicate the week of manufacture. "19" tells the 19th week.

Using this information, you can determine that the dishwasher was manufactured in April 2001.

However, interpreting the year can be tricky in cases like "AB820," where the "8" could indicate either 2008 or 2018.

In such instances, you'll need to rely on your judgment and the appliance's appearance to determine whether it's closer to being 5 or 15 years old.


With Samsung dishwashers, you'll have to consider the length of the serial number.

For a 15-digit serial number, the 8th digit represents the year, while the 9th digit indicates the month.

On the other hand, if you have an 11-digit serial number, look at the 4th digit for the year and the 5th digit for the month.

Refer to the table below.

Year Code Year Month Code Month
R 2001 1 January
T 2002 2 February
W 2003 3 March
X 2004 4 April
Y 2005 5 May
A or L 2006 6 June
P 2007 7 July
Q 2008 8 August
S 2009 9 September
Z 2010 A October
B 2011 B November
C 2012 C December
D 2013
F 2014
G 2015
H 2016
J 2017


To figure out the production date of your KitchenAid dishwasher through the serial number, start by locating the serial number on the appliance.

The second to fourth digits of the serial number hold the key to the manufacturing date.

The letter in this part of the serial number signifies the year, with "K" indicating 2000, "L" indicating 2001, "M" indicating 2002, and so on.

The subsequent two digits represent the week of production.

For example, if your serial number reads "M12," it means the dishwasher was manufactured in the 12th week of the year 2002.

    What if the dishwasher serial number is worn away, or part of it is missing, or perhaps you can’t make heads or tails of it?

    That happens. In such a situation, we’d recommend contacting your dishwasher manufacturer.

    Where Do You Find the Serial Number On a Dishwasher?

    It’s usually one of the labels on the inside of the door. Look on the right side or the left side, and you should see it.

    If it’s not in either of those locations, the serial number label could be on the inside edge of your dishwasher.

    To make it easier for you, below are links that direct you to manufacturer websites that tell you exactly where to find the serial number.

    How Long Should a Dishwasher Last?

    You’re happy to know more about your dishwasher, but the information doesn’t mean much without context.

    What is the average lifespan of a dishwasher?

    Dishwashers last between ten and twenty years.

    That said, the lifespan of a dishwasher is not set in stone. Several factors impact its lifespan, so let’s talk about those now.


    Samsung, Whirlpool, Thermador, Maytag, and KitchenAid dishwashers are known to last about a decade.

    Compare that to dishwashers from LG, Kenmore, Frigidaire, Electrolux, Blomberg, and Beko.

    Those dishwashers have about twice the lifespan on average.


    This is something we’ll talk more about in the next section, but taking care of your dishwasher when it’s not in use is infinitely important.

    If you slack off on the maintenance, then gunk buildup and other issues are likelier to happen, shortening the life of your dishwasher.

    Frequency of Use

    How often you use your dishwasher is also important.

    If you can’t go more than two days without running the dishwasher, then yours won’t last as long as someone who only runs it maybe once a week.

    What Maintenance Does a Dishwasher Need?

    Speaking of maintenance, what’s required to keep a dishwasher in tip-top shape? Here’s what you should begin prioritizing.

    Use It or Lose It

    We mentioned before that if you run your dishwasher only weekly that it will last you longer.

    On that note, make sure you’re not refraining from running your dishwasher just to squeeze more time out of it.

    The components in your dishwasher, such as the motor seals, require regular use to work their best. At least weekly, run your dishwasher.

    Clean It

    Your dishwasher cleans your dishes, but that doesn’t mean the appliance itself is clean.

    Where do you think all the food messes and gunk goes when it’s removed from your dishes?

    To clean the dishwasher, use a damp cloth on the door and the rubber seals that prevent water leaks.

    If you do this regularly enough, there should be no need for soap or a cleaning product.

    That said, for stubborn messes or caked-on grime, a dollop of your favorite dish soap will remove this unwanted residue.

    Don’t forget the spray arm, which is one of the most essential parts of your dishwasher.

    Without it, water can’t spray from the appliance onto your dishes.

    To clean the spray arm, you can use a damp, soft towel.

    Cleaning with a toothpick can get messes out of all the nooks and crannies, but you should only have to do this twice per year.

    The rest of this cleaning should be done once every few weeks and no more infrequently than monthly.

    Wash the Filter

    Some dishwashers use a filter. If that’s true of yours as well, then you have to take it out about weekly and wash it in your sink.

    Grime and food messes that become trapped in the filter inhibit your dishwasher’s performance.

    Is It Worth Fixing a Dishwasher?

    One day, your dishwasher just stops working.

    It’s not that old, but you wonder if you’re better off paying for repairs or just biting the bullet and upgrading your dishwasher.

    That depends, so let’s assess when it’s better to repair versus replace.

    The average cost of dishwasher repair is between $50 and $600.

    If your filter is faulty, that costs $50 to $100 to replace. A new sprayer arm is between $75 and $100.

    Maybe your water inlet valve is damaged, in which case, you’d pay $80 to $125 for a new one.

    Does your dishwasher door not stay locked once you close it?

    Then, you’ll pay $150 to $250 for a fresh lock. Pump issues are the costliest, priced at $150 to $600.

    Then, you have to factor in labor costs, which can ratchet up the repair costs to around $400 or $600.

    A new dishwasher can retail for up to $1,500. If yours is built-in, the price range is $300 to $1,000.

    A drawer dishwasher costs $270 to $1,380. Countertop dishwashers are among the least expensive, with a price range of $200 to $400.

    Again, labor costs must be accounted for, with the installation tacking on $110 to $270 in addition to what you paid for the new dishwasher.

    So, repair or replace, which will it be? If your dishwasher is still covered under its warranty, then fix it.

    You might not have to pay for all the parts, which is especially great if your dishwasher needs costlier repairs.

    For a dishwasher that is close to a decade old and is no longer under warranty, you’re better off replacing it.

    Some dishwasher repairs are so expensive that it’s not worth turning around in a few years and spending more money on a new dishwasher.

    Just buy one now.

    How Do You Know When to Replace Your Dishwasher?

    Besides the dishwasher outright breaking, how else do you know when you need a new one?

    Here are some signs that indicate that it’s time to put your dishwasher out to pasture.

    Lots of Noises When Cleaning

    No dishwasher is perfectly quiet when washing dishes.

    However, there’s a difference between the normal chugging and whirring sounds and what you’re hearing now.

    These sounds concern you.

    They should! The dishwasher sounds are likely the motor straining to work. It’s only a matter of time before it pushes itself to the point where it dies.

    Exterior Damage

    Has your dishwasher seen better days? Perhaps there’s rust on the metal exterior, or the body of the dishwasher is cracked.

    Neither are good signs. If your dishwasher is cracked, it’s likely to leak.

    Rusting isn’t only a sign of age but of misdirected water too.

    Dirty Dishes After a Wash or Several

    Listen, sometimes your dishwasher misses a dish or two. It happens.

    More and more, though, half the dishes on the rack are still dirty. Even if you wash them twice, they still don’t come out perfectly clean.

    This indicates that it’s time to call it a day with your dishwasher.

    Water Leaks

    Your dishwasher should not leave a puddle on your kitchen floor.

    When leaks occur, more than likely, the problem with your dishwasher is severe enough that you’ll want to shell out for a new one rather than pay to repair it.

    The Door Doesn’t Stay Closed

    Most dishwashers don’t even work if the door isn’t sealed.

    If your dishwasher does run with an open door, then watch out, as it’s going to get messy soon with all that splashing water.

    Which Brand of Dishwasher Is the Most Reliable?

    You’re going to buy a new dishwasher for the first time in quite a while.

    If possible, you want a dishwasher brand that will hold up well to regular wear and tear and last for upwards of twenty years.

    Which brand is that?

    According to several polls, including The New York Times, Bosch is at the top of the pile when it comes to dishwashers.

    Bosch is a home appliance brand that produces large-scale dishwashers. Some of the models have three racks rather than the standard two.

    You can also select from several wash cycles for quickly cleaning dishes or giving them a deep cleaning.

    The Bosch 300 is among the most esteemed dishwashers from the manufacturer.

    This built-in dishwasher measures 32 inches by 24 inches by 24 inches.

    It features a sturdy stainless steel frame, three drying racks, 16 place settings, and six wash options.
