Jon,
I grew up surrounded by top load machines and from what I can tell, there was never a problem (that I know of) with stain removal. Front load machines have only recently (last 10years) started to become popular here. As with all other posters, I can appreciate that you want to get the best results for your investment, you don't want to do any damage to your clothes and would rather not have to lug them to the laundrette....
So I suggest that even though it will cost more, you may need to try this...
-only fill to 2/3 or 3/4 with clothes - this will let them move more freely and reduce linting...wash more loads rather than load to the recommended capacity
-if the water temperature is hotter than about 60c, then the enzymes in your detergent will be pretty ineffective - they die - try the warm wash as the enzymes will be able to work. As an example, my old Oz made Hoover Electra's longest 'wash' component was 21min....and I never, ever had a problem on a warm wash.
-Which magazine tested powders and found Ariel was best in warm water 30-40c
-remember, European front load machines generally heat from cold - the machine you are using does not which doesn't give modern detergents much scope to be effective
-when using front load (British automatic) powder in a top load machine, you may need to increase the dosage to about 1 1/2 - 2 times recommended...there is a lot of water in which to get effective cleaning power and the cycle isn't long for it to work...
-rinsing may be compromised with increased detergent so you could try 1/2-1 cup of cheap WHITE vinegar instead of fabric softener...it will disperse the residue better and fabric will be soft (though not 'conditioned' soft)....when dried you shouldn't smell like a chippy...try it...it is cheaper than conditioner and is an option to iinvestigate
-pretreat stains both front and back of material...try vanish spray or similar. They should be sprayed and washed virtually immediately or you risk fabric damange....or soak in a bucket in your room, ring out and put in a plastic bag to transport...the soak option is a better (and cheaper) option especially for tough stains like food spillage
-if you continure to use conditioner, use a front load amount of fabric conditioner and mix with water. It will disperse more evenly...you should still get good results and it could actually be aggravating your skin - it nearly kills mine so I avoid it regardless of how pleasant it smells and especially if tumble drying
I'd be interested to know how you go....
