Janak,
One thing I absolutely loath is when people call out others like you did with Jacob.
Wales is part of Great Britain therefore you were both right about where Hotpoint washing machines were manufactured. All machines - 18 series, 95 series, WM series, WMA series and subsequent were manufactured there until 2009 when production was moved entirely to Italy and as far as I'm aware Poland.
As for the takeover of Hotpoint, yes Indesit (Merloni Elettrodomestici) bought a 50% share in 2001 but the full takeover didn't happen until 2005. The WMA series was not a Merloni design and they were produced by Hotpoint in the UK and under their own control - Merloni basically just ran off with the profits until the full takeover and the first Merloni influenced design was introduced - the WF series.
It pays to do your research,
James
