I have just purchased a full size dishwasher and due to kitchen space I have tried to run this by sitting it on top of a worktop off the ground. However the dishwasher does not seem to be taking in enough water. It does start to work and pump water into the dishwasher but then stops and states there is a fault. When sat on the floor this works fine. However I do not have room on the floor to store my dishwasher. If I bought a longer water pipe would this solve the problem as the one I am using is very tight to the water inlet pipe? Or any other suggestions?
