Hi All,
Reading posts and noticed the only reference I think to a possible leak in the dishwasher and or hose is in a post from Whale. Am I wrong?
Whoisit did you have someone investigate your dishwasher? I read in your post all pipes in kitchen were checked but what about the dishwasher?
The leak I believe is from your kitchen into a kitchen below?
I had sometime ago a neighbour below me having water leaking into their kitchen cupboards. After investigation the dishwasher had a hole in the outflow pipe where it had been squashed against the wall causing the pipe to crinkle and leak, although a small amount, over time it sits somewhere and then drips into the property below.
