when i switch the dishwasher on to select a program all the greens led’s illuminate on the right hand side along with a beep. Then, only the far right green led (glass setting) is illuminated?? As its the only program available I can only use this setting which is the coolest wash available and does a poor job!! I have searched the net but cant seem to see anything similar. The dishwasher heats up correctly for the glass setting and it drains perfectly fine, no unusual noises. It just ends its program a lot sooner than usual as its only completing the glass/fragile program. I hope someone out there has seen this before and give advice, cheers.
