Bosch SHU53, Dishes not being cleaned properly

5 posts in this topic

I have a Bosch SHU53 model dishwasher that for the most part has been fairly reliable  (other than my go arounds with the 11A heater connection on the PCB), however just in the last couple of months the cleaning has gone down hill.  First it started gradually by not getting everything clean and food stuff was being baked on.  I then started rinsing everything by hand before loading and using the scrub cycle.  That helped but now a white film and residue appears on all the dishes and it's seems to be getting worse making the wife quite unpleasant.  I do have hard water, use Cascade powder and keep the RinseDry loaded, one item to note and that is that I have always noticed that at startup I'll get a burp of water (couple of tsp.) out the air gap, just enough to leave a little ring of water on the sink.   I regurally pull the gap cap off and verify that debris isnt plugging it...

 

Ran the diagnostics test and have a 1in the window, Aqua sensor, however what I understand that doesn't have any effect on washability.  

 

Any ideas on where to go from here?

Make sure if using Cascade it is Cascade Complete. Dark Green box. Google government/phosphates and learn more. Remove that round filter on the bottom of the dishwasher and make sure it is clean. Also be sure to purge faucet at sink and confirm hot water before starting cycle. Likely others here will offer ideas but these are the obvious basics.

Are making one of the three deadly dishwasher mistakes?  http://appliantology.org/blog/1/entry-694-the-big-three-deadly-dishwasher-mistakes/

 

Is the dishwasher pumping out completely between cycles?  

 

Have you scrubbed the coarse and fine filters?  Even a little occlusion of those tiny holes will starve the wash impeller and produce poor cleaning results.

UPDATE:

 

I think there was more then one contributing factor to the problem.  I had ran a bottle of "Glisten" a few months earlier to remove the white calcium sheen that was building up inside on the walls of the washer.  That must have started the chain reaction. The bottom flat screen underneath had huge chunks of the white stuff stuck to it and had to be literally scrapped off and the micro-screens seemed to be half-way clogged as well.  I performed a thorough  cleaning of all the sprayers, flat screen and bought a new mirco-filter.   I found this stuff called "Lemi-Shine" booster that I ran along with the Cascade complete baggies while I waited for the new screen to arrive, 100% improvement.  That told me that it was mainly the soap that had changed and not so much that the washer was just old and needed replacement.  Anyway with the new screen and the booster the dishes come out cleaner then ever! The wife is happy....I am happy...thanks for the help!
