When I try yo start my Prima dishwasher It just shows E4 Overfilled. Too much inlet water. As there is no water to be seen and I've only used the machine about 4 times what is going wrong. I've searched the internet for an address as there is no address in the manual so what can I do. I am in my eighties and cannot move the machine out of position to see the back. Thanks
