It's the most exciting thing to have happened for ages ... I have a new dishwasher!!!!! But I have to set how hard the water is ... have checked the Thames Water website but cannot find any localised info - anyone happen to know?
Another tip Julie - don't bother to fill the salt dispenser with expensive salt, simply buy dishwasher tablets that have a "salt function". Tesco home brand are great and cheap - make sure you get the "salt function" ones!
