I have a 6 year old GE dishwasher. The past couple of days we noticed that the dishwasher detergent powder is not being used up. We thought we've put too much detergent or it didn't get dissolved properly etc.. Today we ran it during the day to observe. Looks like there's not much water injecting/circulating inside. Previously during rinse cycle a whole lot of water used to channel its way into the sink drain like it's supposed to. Now there's hardly any. I'm thinking there's a block in the water source to the dishwasher.
We've also had another issue with this unit. The dishwasher racks are corroded and we've repaired some corroded parts with plastic caps / resin paint. There's still some more corrosion. DH thinks the rusty bits fell off and blocked the water pipe.
Please offer suggestions on what to look for. Is there anything we can check before we call the plumber? We do lot of fixing up of basic plumbing issues at our house.
Thanks.
