Hi I have a Whirlpool G2P DWI integrated dishwasher, that seems to have an intermitent fault. HEEEEEEEELP! The fault occurs every so often, during a cycle it starts to intermitently beep, if the door is opened the start light is flashing but continuosly flashes not for a number of flashes to show a fault. I then have to hold the start down for a few seconds to reset and try again. Soetimes it works other times it won't work for a few days and then starts again. Do I just have a lazy dishwasher that likes a holiday every now and then or is it something fixable?
