The chamber on the arrestor has to be full of air for it to work - When you refitted, did you check the chamber was free of water?

No, I didn't give that any thought to be honest. I just loosened it up at the pipe end, rotated the chamber so it is pointing upwards, then tightened the pipe end up again before connecting the washing machine's hose.

If you type stopcock, you can see the whole word (and in fact it is correct) however, if you split it to two words, that is when you get the annoying !!!!.

ok Glasses on now not sure washing machines use aquastop, so that rules out the issue they can get.

They can do, we got a new Bosch washer in the Black Friday sales that came with one.


Wasn't mentioned anywhere on the spec list oddly enough.

Indeed, very important.
