My Hoover Aristocrat (some hopes!) had a leaking soap drawer. The basic problem is that the jet in the back of the drawer box is aimed at the front of the drawer, presumably to ensure that the soap gets cleared. Putting a restrictor in reduces the problem, but then the drawer doesn't get cleared.
What is needed is a series of vertical and/or nearly vertical down-pointing jets. Achieve this by drilling two or three rows of 2 mm holes over the first 150 mm of a length of 8 mm copper or brass tube (get it from a plumbing/gas supplier or good model shop). The total length of the tube needs to be about 280 mm. Close off the end close to the drilled section with a capillary soldered pipe end stop, a wood or metal plug, or squash it in a vice, put one fold in it an squash again. Put a slight bend in the pipe about 200 mm from the closed end to suit the angle of the entry pipe in the soap box. Feed the pipe through the box and out of the entry pipe. If the bore of the entry pipe in the soap box is too small, open it out to 8 mm, to allow the new pipe to slide in it. Push the rubber water supply pipe over the copper/brass tude and back on to the original soapbox inlet pipe.
Place a plastic "squeeze" type pipeclip on the rubber supply pipe to ensure that it seals on to the copper pipe. The rubber pipe will be too big to self-seal on the copper pipe, that is why the clip is necessary. It will self-seal as originally fitted on the soapbox inlet pipe.
I modded the cold fill sectiuon of my machine in this way several years ago and the problem has never re-ocurred.
Cost - nominal!
