I would be very supprised if that's a genuine Miele part. Miele are an *extremely* high end German domestic appliance manufacturer and their products are normally top notch from every perspective, including electrical.
They quite litterally pride themselves on the quality of their machines, components and engineering.
I would bring the item in question to the attention of Miele in Germany by email. ( info@miele.de ) to ensure it gets read in English perhaps CC it to Miele here in Ireland info@miele.ie
It's very odd that that label does not contain Miele's logo too
Their products usually have the following codes:
Type: (short code with dashes)
Model: (longer code with dashes)
Serial: (long numeric code)
Is it possible that some local re-distributor is knocking together boxes to make the installation easier?
The grounding arrangement is, indeed, very odd.
Surely there's a ground on the socket outlet ?!
Normally, a European washer or dryer is connected to a 13amp (UK/IRL) or 16amp (Rest of EU) outlet. (230V 50Hz) [typically protected by a 30mA RCD [GFCI] and on a 16A or 20A radial (UK's different due to the ring circuits - 13A fuse in plug, 32A fuse on ring circuit).
Miele's North American washers have a heafty internal heater, so their US model operates on a 240V 60Hz US dryer circuit.
US washers typically just use hot water from the tank.
Most European washing machines have abandoned their hot water connector.
The reason for this is:
1) They use so little water for the wash that the water would be still running cold by the time the machine had filled!
2) They use a "profile wash" where water is gradually heated to maximise enzyme activity in the detergent (there's a euro standard for this!)
3) It means the wash temp. can be accurately controlled from 30C to Boiling.
Older machines always had hot and cold fill as they used considerably more water during the wash cycle (even in Europe)
