Hello. My brand new Hotpoint WF860P has had this problem from day one. After about a day of inactivity I open the door to find water in the drum. I assume it's from the overflow hose that is plugged into the U Bend. I have positioned the height of the hose well above the drum. Infact the entire plumbing set up is exactly the same as used for 9 years on my old Creda. That never had a problem. Could it be a faulty shut off valve? Is that possible on a brand new machine? Hotpoint have told me it could be the shut off valve. But alas refused me a replacement machine (as do Comet) after only 2 weeks. Please help.
