Every time i try to turn my hotpoint wt960 washing machine on it blows the main fuse i have changed the fuse in the plug and tried a diffrent socket

Sounds like you have eliminated a few possible sources of the problem, but we have to dig deeper--

Do you have some way of checking for shorts and continuity?-- Like an Ohm meter?- or a continuity checker?

YOu will need to remove the control panel, and check for a short either on the cord, or inside the control panel.
Inside the panel, the 3 wires from the power cord, attach-- Can you see the Green and then the WHite and black leads?
With the Plug out of the wall, You should get infinite ohms between the White wire and ground, as well as the Black wire and ground-- A low ohms reading indicates a short to ground-- Now we have to find that short.

Can you trace the circuit thru from Black wire, thru the controls, back to the white wire-- and can you check for shorts at points along the way?

Let me know what you find, and we'll help you further.
