We own a slimline indiset dishwasher, and we find when we got it it was ok, but after a week on the sides of the dishwasher we were getting a nice build up of sludge? So knowing thats not right me and my mum cleaned it top to bottom, nook and cranny, but it always does it and we have to scrubb it at least once a week, and the sludge keeps coming back, we tried that 'finish' stuff to clean the dishwasher but that didn't work, we rise the plates before they go in, give it salt, extra stuff to try and clean it ect ect, but it keeps getting minging!! And usally the dishes are ok ish but every load you can guarentee at least 3 thing being filthy. It also does not clean plastic items well at all!! It leave a clear sludge on the plastic, which you have to wash off, its kinda cheesy smell to it too, we have tried diffrent types of dishwasher poweders. Somthing wrong but what?? We are seriously considering dumping it as none of our old dishwashers did this and it a pain! Help please!!
