smeg intergrated d1612c dishwasher problem?

hi
need some help/advice....when i start the dishwasher ie.select program,close door...it starts as if everything is ok...it seems to make the relevant water noises...filling ??...but just when it should kick in and start its cycle,it stops and goes no further..anybody any ideas,the wife smelt a smouldering smell before this started,i've had the front panel off and checked voltage and contacts seem ok..really stumped,i've also done the reset.....
