congrats Andrew !
ChesterMike is really right : you can wash such things one wouldn't dare to throw into a washing machine. Camping tents, backpacks, wetsuits, lambswool/cashmere jumpers, loden jackets, raincoats, duvet jackets/coats, ski suits .....
If the W48XX servicemode code is right for the W30XX too you'll be able to adjust the "sensitive" option for a furter rinse and a rinse level like the delicate cycle
@ Mike(nmassman)-Liquids : i have no problem, unless I use wool detergents on regular or permapress instead of wool/delicate/handwash cycles. Same applies to my brother's machine with the honeycomb drum. Maybe your liquids are so sudsy like Woolite ? Maybe you've extremly soft water ?
