    Re: Identifying Date Codes and Serial Numbers

    Recent Hotpoint Dishwashers have started to use the Indesit format,

    Serial No. 9 10 02 0895 for example is

    First digit = year of manufacture – 1999
    Second two digits = month of manufacture – October
    Third two digits = Day of manufacture- 2nd October
    Fourth remaining digits = Build number that day – 895

    The ‘Code’ number on the rating plate identifies the factory etc , vital for correct parts ID.

    Hotpoint two digit date codes from December 2003 to July 2006 start at 24 for December 2003 through to 55 for July 2006. Generally Hotpoint date codes only went up to 96 then started again. Many years ago some machines did go past 96, but I have not seen any for a long time. You can work back from DC24-Dec 2003, to get any earlier months.

    They are normally the first two numbers of the serial number. Many years ago they used to be the last two numbers, often in bold or slightly apart from first five or six digits.

    Electrolux group serial numbers (Zanussi, Tricity Bendix, AEG etc)
    First digit = year of manufacture, next 2 digits = week of manufacture, rest are just general factory numbers.
    34900122 = 2003 week 49

    Pre 1987 Zanussi machines, first 2 digits = year, next 2 digits = month
    8607 = July 1986

    On Whirlpool 12 n.c. nos the last 2 are the colour. some undercounter double ovens made by stoves for whirlpool which are stainless steel have the wrong 12 n.c. The number will come out green and not steel

    Ariston Washer Dryers.

    The first digit is the year, the next two are the month and the 4th and 5th digits are the day.

    EG 111023037 is the 2nd of November 2001.

    Same formula as the post above for Hotpoint dishwashers Geoff, using it on all production for a while now, together with the commercial code.
