Indesit D63 dishwasher not filling with water. No matter where the cycle selection knob is pointing to, it appears to be on the same part of the cycle. When we poured some water in, it was drained completely and we have checked the pipes for kinks and blockage with no success. The filter is clean and there is plenty salt in the machine and it is only 18 months old. any advice on what the problem could be?
