Zanussi cooker ZKC6020w pnc 948522181

Went to this cooker for a trip fault (earth leakage) and found
front left plate (large single circuit) six/seven position switch
had two contacts slightly welded.Teased them apart and mega test was ok.Ordered new switch and fitted,five weeks later it has done it again,switch welded contacts as before.
Just wondering whats going on here and whether this is a recognised fault or factory fault.A solution would be appreciated.Found this post and wondered if it has any bearing

regards steve
