- Fix-It Beginner
our de540x was always needing rinse aid top ups, when the soap cap dispenser broke, it was time to get a replacement. watched the video, seemed very straight forward, so gave it a go. had one screw that had sheared in the old door of the dishwasher (nothing to do with the new part), hence the one less star for ease of fitting. now don't have to look at the rinse aid light illuminated every other day anymore on the dishwasher and the cleaning of glasses has improved.
