Do suds ever full go away?

[rlpenny]

I've been diagnosing (w/great help from this site) a low water fill problem on my 1993 Kitchenaid DW (WP but still dominate Hobart influence model). I've completed 3 maybe 5 rinse/hold cycles test the water fill level and on several occasions have suck a quick peek into the unit to gauge wash arm movement at varying water levels.

I've noticed that even after a 3rd 4th or possibly 5th rinse/drain cycle I still see plenty of suds. They are small and quickly dissipate after some seconds nut I've never observed this before. Actually I've no reference point other than supposition that suds should be minimal.

For those in the know, what level of suds are typically observed after or towards the end of first or second rinse cycle?

If the bubbles dissipate quickly, it may be a normal/minimal amount of residue creating them.  Plus, there's a lot of churning going on so it may not be suds at all.  They don't call it white water for nothing in recreational rafting circles.

 

If the suds were more persistent, I'd say you might have a rinse aid dispenser leak.  On my KDI21, something seemed to be happening with the rinse aid and when I filled the glass carafe for the coffee maker after it had been through the wash, I'd get bubbles on the water surface that wouldn't go away.  I had to rinse the carafe out any time after it had gone through the dishwasher.  I'm fairly certain it was an issue with the rinse aid dispenser, but we soon sold the house and left the machine behind so I never pursued it.

I've not yet figured out where/how the rinse agent is dispensed. I know where it is filled but the screw-on cap/plug has that oring so I don't see where the agent could come out. But, I did notice tonight on closer inspection there is a teeny hole in the long cylinder leading to the reservoir that would be on the water side of that oring. But the cap appears to practically seal to the door. Maybe it only takes a drop of agent because that's all I could imagine coming out.

The amount of rinse aid used is minimal. A little bit does go a long way otherwise you'd be refilling the dispenser all the time. If you've changed your detergent recently to something that has a rinse aid included in its formula you may take that into consideration.
When my aptmt complex installed a new DW in my aptmt I switched to a detergent with rinse aid. I stopped using it separately because of foaming problems and that fixed the foam issue.

Yes, very little rinse aid is required.  We have fairly hard water here, and I have my Miele DW set for the least amount of rinse aid to be dispensed:  1ml.

 

I run the dishwasher once or twice a week.  The Miele has an indicator that lights when the rinse agent reservoir is empty.  It took a year for that light to come on after filling the reservoir when I first got the machine.
