Whrilpool dishwasher washer arms not spinning

[Kevmce]

I have a whirpool ADG 7550 dishwasher, the problem stared with a really loud clicking noise, so replaced the drain pump, which stopped the noise, but now the spray arms are not spinning and is not washing any thing, it is filling upend heating the water but nothing else? Any ideas

Check if the spray arms are blocked by garbage.

Checked that all, think it must be another internal pump.? Any other ideas.
But thanks anyway zipper.

If the spray arms are clear & there is no other pressure loss anywhere then could be a problem with the circulation pump. Do you hear it running...or even buzzing?
Post the 12 digit number on the door sticker if you need more detailed info. It starts with 85....

It's defiantly working just not pumping water through, here is the code: 8542 755 15820' how easy is it to change the circulating pump and how much do you think it will cost, cheers again Zipper,

It is an expensive piece of kit http://www.partmaster.co.uk/cgi-bin/product.pl?PID=2303497&query=480140103011
I would exclude all other possible causes before shelling out for one...like a bad motor capacitor, jammed impellor, & make sure the dual bore pipe that feed the spray arms hasn't popped out of its socket in the base (very common on these models). Your best plan is to run it with the side-plates off. If the circ pump buzzes but doesn't run it could be down to something as simple as a £10 capacitor.
