I have a CDA integrated dishwasher. We started having problems recently when the dishes were still unwashed after the full wash cycle. I have checked the spray arms and the filter at the bottom but cannot find any blockage. I rigged the machine to wash when the door was open and I saw that although water was coming out of the bottom rotating arm the pressure was such that the jets were only going an inch or two into the air, and no water was coming from the middle or top jets. Has anybody any idea what could be the problem. I wondered if it could be a problem with the pump, but in my ignorance I thought a pump either worked or it didn't. It seems it is pumping water through but with much reduced pressure. There are no leaks and all other kitchen appliances are functioning okay. Can anybody help please?
