    I have a Hotpoint FDM550 dishwasher. It an take ages to start to cycle i.e need to open/close the door several times before start button works. Then regularly/most of the time it stops mid cycle and needs to be restarted , which again can take a while also. No lights are displayed when it stops mid cycle. Anyone know what the problem could be ?
