electrics for a dishwasher (all to do with 13a fuses)

[vicars]

Hi, I have a dishwasher that needs a 13 amp plug. I am wondering if I can use the following safely:
1. a 13 amp multi plug that allows you to have 2 things plugged into one socket.
2. A single extention cable that has a 13 amp rating.

The socket is currently used by the gas hob and just needs electricity to do the spark. However I am concerned that I should not use an extention cable plugged into a square multi plug thing despite them all being 13 amp fuses. Is this a perfectly safe way to plug my dishwasher in or should i avoid an extention cable at all costs?
Very much appreciate any replies. Thx.

Think you should get an electrician to put you right , as better safe than sorry .

you require a single unswitched socket at the rear of the appliance under the worktop with a control switch above the worktop , usually a switched spur (f.c.u.)
the thought of an extension cable on or near the floor behind an item that may leak water under fault conditions is
not safe

It is unwise to have anysort of appliance connected to a extension.
According to Miele, they say if an appliance is connected to a extension, there could be a danger of overheating, shock and possibly fire.
