Hi I'm John I will help you with the problem.
Have you removed the raised screen to the right at the sump to clean that out ?
give the number 506 a squeeze and lift it off the screen in the sump can get clogged up.
And always scrape the dishes before doing the wash.
Thx for teh diagram. Whcih part number is XXXXX "raised screen" that I need to remove and "clean out"? is it 506? if so, i've tried to remove that, but it seems there are other parts I need to remove first, so I can't get that off. Do you know which order I should be removing parts? And is it just pulling them off or some other method?
(Yes, we always make sure we get the water hot. I've measured the temp as well. Plus we use the extra heat boost feature of the dishwater)
Heres the parts breakdown you may have to pull the unit out to get to the sump .
Its easier to get to all the parts that can cause the problem .
The real problem is the food still on the dishes when you wash .
So once cleaned out don't add plates or bowls that have food still on them.
its the only way to stop that problem.
Ok, I removed the whole tube that sends water to tehj upepr spray arems and removed 506. Now what. Do I jsut pull out 508? It doesn't seem to want to come out. There's water in it for sure down at the bottom and some gunk.
What about the gunk you said was in the sump was it just water ?
If its just water then check number 329 its a flapper valve and it can be stuck by food particles.
The best product to use is Dishwasher magic it will clean all the inside parts and make the unit run like new again.
its a very good product it works
So based on what i've told you, do you think this build-up was my problem? I never have an sisue with food particles being left in the dishwasher, and none was in the sump. Just thie white gunk. So do you think i still need to take the rest apart and check the flapper valve?
if not, besides dishwasher magic, which im not sure I can find anywear today, anything else I can try besides white vinegar?
Open the door and wipe down the very front of the tub it can get gunky at that location .
And you have to stop putting the dirty dishes in without scrapping them off or the problem wont go away.
Try the heavy duty cleaner CLR pour a few cups in and let it go through a cycle .
If that doesnt do it nothing will.
