Blocked Sizing Plate In A WP Built DW
Hi Joshua, The first picture you posted of a clogged sizing plate had a BROKEN GRINDER BLADE, it was NOT turning, It has NOTHING to do with how the DW was being used, the sizing plate will clog like the one in your picture even if the dishes are 90% rinsed off in just a few loads if the grinding blade is NOT turning, and only if it is not turning.
This is the most popular design DW in our area, almost every other one of our customers have a DW that has a pump like this. We work on hundreds of these machines every year and we NEVER see clogged sizing plates like this unless the grinder blade drive is BROKEN.
One of these DWs will not wash dishes properly even 6 times with a broken grinder drive blade without clogging.
