My nappies have survived better in my front loader than in mums top loader. I nearly cried when we were living with her and I watched all the fluff come off my beautiful nappies

I usually wash at 40 degrees (mine connects to both hot & cold tap) and do the occasional hotter wash if they get stinky.

The elastic has gone in some of my nappies, but I reckon that's from the odd strip wash I've done with vinegar (I do a different strip wash now ) oh, and also the dryer can kill elastic too.

It might be coincidence that the elastic was about to go anyway, and it just happened to go with your new machine.
