How Bosch Encodes Age in the FD Number
Unlike brands that embed dates into complex serial sequences, Bosch uses an explicit 4-digit FD (Fertigungsdatum) production index based on a rolling base formula:
Example: FD Number FD 9406
- Prefix (
FD): Standard label designating "Fertigungsdatum" (manufacturing date). - First Two Digits (
94): Year code offset. Adding 20 (94 + 20 = 114) yields 2014. - Last Two Digits (
06): Month of production = June. - Decoded Output: Manufactured in June 2014.
Example 2 (Modern Unit): FD Number 0408
- First Two Digits (
04):04 + 20 = 24, representing year 2024. - Last Two Digits (
08): Month of production = August. - Decoded Output: Manufactured in August 2024.

Frequently Asked Questions
What is a Bosch FD number?
FD stands for Fertigungsdatum (German for 'production date'). BSH Bosch Home Appliances uses this 4-digit index on all rating plates alongside the E-Nr model number to record the precise month and year of factory assembly.
How do I calculate appliance age from a Bosch FD number?
Take the first two digits of the FD number and add 20 to determine the year of manufacture (for modern appliances, e.g. 94 + 20 = 114, representing 2014; 04 + 20 = 24, representing 2024). The remaining two digits represent the month (01 for January through 12 for December).
Where do I find the FD number on a Bosch dishwasher?
On Bosch dishwashers, open the door and look along the top metallic edge of the stainless steel door panel. The FD number is laser-etched or printed on a label alongside the E-Nr model number.
