Kitchenaid KUDS40FVSS3 dishwasher fills when off
Posted 25 March 2011 - 02:26 PM
When "off", this dishwasher allows water to seep into itself, until it starts dripping out the front.
I can initiate a "cancel", which drains the unit. Then if I just leave it alone, it will slowly take on water until it spills out the front.
Have replaced the inlet valve, still have the issue (same issue w/ original and replacement inlet valve).
Any help appreciated,

So it seems that for some reason as the RO unit drains off water in the process of doing its filtering, that drain water somehow makes its way into the dishwasher drain hose and back-fills the dishwasher. So the dishwasher is filling from the drain, not the inlet valve.
I have pulled the "Y", no clogs, I have inspected the D/W drain inlet to the disposer, no clogs ...
I can visualize what is probaly happening, but I don't see "why" its happening ...
The RO unit should just be draining into the disposer without any back-draining into the dishwasher drain pipe and the dishwasher.
I think I'm going to reconnect the "Y" drains at the disposer and monitor things to see what happens ...
BTW the dishwasher drain hose is run high up against the underside of the countertop.

The first drain hose (drain loop) contains a check valve which should prevent backflow, unless of course, it was tossed out at installation. More than once I've heard "the unit came with 2 hoses, I chose to use the long one"
