Hi Lara its easy for me to do as i am Bosch engineer but dont want to underestimate an eco warrier so this is how step by step :- Unplug machine, remove lid by pushing up plastic lug about 2" in from each side at back and push back lid at same time, remove both side panels 2 screws at front edge of each (T20 Torx screwdriver), Remove outer metal door 3 screws each side starting at bottom,remove bottom plastic kickplate 1 screw each side,remove steel plate behind it and matting,remove top plastic corners left side of machine, front one unclips back one has screw inside it,you will see large square plastic water jacket on left side remove the 2 metal bars holding it in place now be very careful the side of the jacket facing the machine is wafer thin dont pierce it, put bowl on floor and lift jacket out and away WATER WILL POUR OUT OF ITS SPOUTS so you must catch this in the bowl leave hoses attached, just to the front of this is the pressure chamber with 2 micro switches mark plugs or photograph these and remove, prize up chamber and remove also clear hose that runs from it to the sump, clean sludge from hose,photograph chamber in case you forget how to reassemble it, remove top micro switch and little black arm, prize off top of chamber and clean out remove and clean red float and black plastic insert, now you are ready to reassemble points to watch are :- make sure black "O" rings are in place when you refit water jacket spouts in them,push clear front hose fully home each end and in clip,dont forget red plastic rod which fell out of chamber when you lifted it up ,then reassemble everything in strict reverse order you removed them, job done. Well you did ask! (sounds a lot but i can do it in about 45 mins including including coffee) am more worn out writing this than doing job! Cheers
