Hi all!

My less than 3 years old dishwasher is having a problem. The spray arms won't engage during washing.

Solutions I've tried:

-making sure the arms can spin (they can)
-pulled off lower spray arm, check for clogs (no clogs)
-removed the feed tube assembly (no clogs)

The dishwasher is in the range of not new, but definitely not old. So I'm a bit out of ideas.

Thanks!

Hi,

You're missing the last digit in your model number, here's the results I get below:

WDF520PADW2
WDF520PADW3
WDF520PADW5
WDF520PADW7

A common problem on these is the wash circulation motor going bad thus the spray arms won't spray at all.

So I'd first get my multimeter and take a volt reading on the 2 wires that connect to your motor and see if your 120 volts when the dishwasher should be running, after it fills.

Let us know what you find.
