How Old Is Bosch Series 4 Washing Machine Front Loader?

The Curious Case of the Bosch Series 4 Washing Machine

Let’s be real: washing machines don’t tend to be the rockstars of our home appliance lineup. But Bosch Series 4 front loaders? They’re the cool kid who quietly gets the job done — washing your clothes thoroughly and efficiently since their debut around 2018–2019. You feel me?

If you’ve stumbled on a Bosch Series 4 washing machine and asked yourself, “Hmm, how old is this beast?” — you’re in the right spot. Spoiler alert: the answer isn’t just “old” or “new.” It’s a tad more nuanced, but also way less boring.

When Did Bosch Unleash Series 4 Front Loaders?

Bosch introduced the Series 4 front loading washing machines roughly between 2018 and 2019, and these models remain very much in production through 2025. This means some machines out there might be fresh off the factory floor, while others have heroically survived years of laundry battles.

Popular models like the WAN28259GB or the WAN24126AU flaunt great energy ratings and have been customer favorites for years.

How to Decode the Exact Age of Your Bosch Series 4 Washing Machine

If you want to roll up your sleeves and find the machine’s exact birthday, look no further than your washing machine’s serial number — that little alphanumeric code tucked somewhere on the appliance.

Bosch uses a handy “FD” code system inserted in the serial number to indicate the manufacturing date. Here’s the skinny:

  • The serial number starts with the letters “FD”.
  • The first numeric digit after “FD” represents the decade minus 2. For example, if you see ‘9’, that means the 2010s (since 10 – 2 = 8, so 9 means 2019).
  • The second numeric digit is the specific year within that decade.
  • The next two digits refer to the month (01 for January, 12 for December).

For example, a serial code starting with FD9910 means the machine was made in October 2019.

There’s a free Bosch serial number lookup tool you can use to decode this automatically if you prefer not to do the math.

Why Does Knowing the Age Even Matter?

Good question! Your washing machine’s age speaks louder than you might think:

  • Warranty and service: Knowing the age helps to determine if your Bosch is still under warranty or eligible for repairs.
  • Replacement timetable: Washing machines average about 10-15 years of reliable service. A Series 4 from 2018 might just have a few years left, but a 2019 model? Relatively young.
  • Resale and parts: Older models sometimes have harder-to-find parts, so knowing the age sets your expectations and planning.

If you want to keep the laundry chaos low, knowing your machine’s vintage is actually pretty smart.

Key Takeaway: Bosch Series 4 Front Loaders Are Both Vintage-ish and Fresh

To wrap it up nicely like a freshly folded tee:

  • The Bosch Series 4 front loader lineup started appearing around 2018-2019 and continues strong in 2025, combining tried-and-true features with modern energy efficiency.
  • Your washing machine’s true age is best unveiled by decoding that “FD” serial number — it’s like a secret handshake with your appliance.
  • Knowing this info helps you decide when it’s time to repair, replace, or just give it a little extra love.

So next time you’re staring down your Bosch Series 4 washing machine, remember: it’s not just a washing contraption — it’s a hardworking household champion with a birthday you can pinpoint!
