I haven’t had this long to be honest it’s something I don’t think about. It must be working as everything is good with my washing machine. I maybe have a better idea when I’ve had it longer, the thing is it’s now a part of the washing machine as a whole. There really is no way to check this and I’m at a loss as to what I can comment on.

Good product. It does as it says on the can. No more to say

Fabulous machine, super quiet, powerful, very easy to operate. Absolutely love it. Please note it is quite large (which is not a problem for us as we have a small laundry room) so be aware if it needs to fit under a kitchen worktop.

Didn't realise this was put on the machine whilst being connected

I ordered this to go with my new washer/dryer because our area has very hard water. I do believe it works because I have noticed that I need to use less washing liquid, and my clothes feel slightly softer when they come out of the machine.

Fantastic washing machine when ur going out U get a message saying it's finished how long it got left its qwite

Can only assume it works. No way of knowing, but seemed a sensible thing to do in a hard water area.

Everything I expected from the product. Previously owned a Bosch so not surprised at quality. Much quieter than my last one. Love the fact displays count down timer to the finish of the cycle.
