Hi My daughter has a "New Team" 8.5 kw shower, while using it the other day It made a loud noise as if something had tripped out inside the wall unit. The electrics are still on as there is a low pressure light that is on ,but there is no water coming through. It has stopped working before while being used but has always worked when left for a while but this time it won't. Can anyone help on this matter? Thanks.
