I have a Bosch shu43c02uc22 that won't spray when it's in the wash cycle, but it sprays fine in the rinse/hold cycle.
I downloaded (and actually read) the "The Official Bosch Dishwasher Training & Repair Manual, 2nd Edition, Rev. 7"
as well as "Bosch Dishwasher Multi-Model Test Programs".
Both of these did not appear to have a diagnostic sequence that worked for my dishwasher (either different buttons or button press sequence did nothing), so I guess my first step is to find a model specific manual (already requested) and run a diagnostic to see if it can tell me what it believes the problem to be.
Here's what I know....
It sprays...sort of, sometimes
the Rinse/Hold seems to work (fills, sprays, drains)
when in the wash mode it fills and I believe it sprays for a couple of minutes (rinse first?) and then about 13 minutes in it seems to cycle through a number of different things every few seconds...like it is trying to do something but it didn't work so it tries something else, presumably to try to fix the problem, but that doesn't work so it tries the sequence again a few times and then just goes pretty much quiet.
BTW, this is an awesome site and I gladly paid the reasonable membership.
