I have a problem with the dishwasher. Button 1 and 2 are flashing and the dishwasher is unable to finish its cycle as the water is not draining. I have thouroughly cleaned the filter but still no goo. I read that it may be the pump which requires to be cleaned but it is an itegrated model and I do not know where the pump is situated or how to clean it. Please can anyone help!
