Thanks BC - I was thinking it's like homeopathic medicine - one tab had been watered down in however many litres of water + although she get really excited and vocal when I put the dish down, she only has a nibble and prefers it stone cold later
She drinks loads as well - I will just keep an eye.
PS - I didn't explain in the 1st message - I turned it off mid wash as it bleeps really loudly at the end of a cycle and keeps on every 5 minutes for an hour
I need to find the book to see if I can disable the bleeper as it serves no purpose other than to annoy
The old one used to go beep beep - and that was it
