Dishwasher question

[backlash 1]

Our 9 yr old Whirlpool DW works great except the wife says she has not had to add any rince agent for a looong time, it has not gone down at all. I pulled the panel off this morning and everything looks intact, nothing broken.

Any ideas what could be wrong here???

Model # DU920PFGQ3

no way I would know, but I want to put a guess in and follow and see what the end result is.

I say something is blocking the tube of the rinse agent where it exits

Ya that was kinda my thinking also. I tried to blow it out while holding the slide in the up position but no go. I actually dont even see where the agent is supposed to come out .

I don't know where it would either

Tell the wife to hand wash, but all serious, I just think a big gob of stuff or the heating part gelled the tube shut, but no idea really
