Hello again! Last December, I purchased a second hand dishwasher, hard wired the unit, and replaced some parts that were leaking with your help. The problem we have now, actually started in February, it's not cleaning properly. All the cycles appear to be running, it's not cleaning. The last run, there was still liquid blue Cascade on the inside of the door after it's full cycle. Is it possible the arms are clogged with scale, or some other problem going on with hoses? As I say, it appears and sounds like water is entering, washing, however things do not come out clean. It's an older machine, and was told it had very minimal use by the seller. Not sure on the water temp, however we only use liquid soap, with a rinse aid. Any ideas as to what I should check? Thanks for your time.
