Pete for Model Number wdt720padm2 Hi, I have a Whirlpool wdt720padm and keep getting white residue that looks like soap and a lot of times leaves plastic dishes greasy. I've cleaned the drain tube, spray arms and tub. I did the CLR, vinegar, vegetable oil, different detergents, semi-shine stuff but problem persists. Prior to this issue the circle pump quit working ( would not start ) so I replaced it and now it runs through its cycles. I can't remember if the pump was new or refurb, but could that cause the residue and inefficient cleaning?
Answer Pete, You will want to check to make sure that you are not using too much detergent as this could cause the issue. Also check the pump to make sure that there is nothing clogged in the pump. Also check to make sure that the pump does not have anything clogged in it that would cause the dishwasher to not pump properly. Read More...
