5 posts in this topic

Have a Whirlpool dishwasher model no.WDF530PSYW0 that is about two-three years old that is working ok,except when it drains.After draining cycles there is always dirty water left in the dishwasher.The thing drains except it leaves water in the dishwasher.What do you think is causing this?

Check your drain hose loop.

Sounds like water coming back in from the drain.

Maybe a clogged drain hose.

Could also be incomplete draining.  Immediately after it finishes draining, open the door and check the basin.  If you see dirty water in the basin, you know it's incomplete draining because backflow will not have had time to come in.  OTOH, if the basin is empty after the drain cycle, then check the drain hose riser loop as Brother jumptrout suggested.

I've had many of these, included my Kitchen Aid DW that needed a drain pump. They always seem to work when yo cancel/drain, but every two are three loads it won't drain completely. I suspect they get a partially stripped impeller on the Drain pump which will sometimes drain and other times not. If the drain loop is OK I would check the drain hose where it exits the drain pump, there a check valve built into the hose to prevent back flow, it's just a flap that I have seen somehow get stuck on the wrong side of the lip built into the hose, just after the bend.

If after that, I'd replace the drain pump.

Here's you're model.
