Product review (4 stars): Good overall with minor reservations
I purchased a Bosch SHX55 five months ago so have had an opportunity to evaluate it under many conditions.

PROS: The unit is a good overall dishwasher. It is reasonably quiet. It cleans most things well and the red light that tells you if it is running is a nice feature. Its top shelf can be elevated such that very large plates and chargers fit comfortably on the bottom without affecting the top washing arm. Properly loaded, it holds quite a number of place settings. It is not necessary to put each piece of silverware in the slotted basket guides. Silverware seems to get clean jumbled into the basket as well. The wash cycle is somewhat long (~2 hours) but not particularly objectionable unless you are having a party and need a much shorter "half cycle"--which this model lacks.

CONS: Rinse agent is an important component to properly dry dishes as there is no separate heating element. Regardless of rinse agent, however, plastic items do not come out dry.  Any items with egg yolk result in a powerful odor that is transferred to all dishes contained in that load. This last item is extremely irritating but if you carefully wash any dishes or utensils containing egg yolk before placing them in the DW, the odor is minimized. Ideally this is not something one wants to do, but the stench of the odor is enough to warrant this kind of pre-washing. Another technique I have used after washing egg-soiled dishes is placing 1-2 TB of unscented chlorine bleach in the bottom of the unit to try and neutralize the after-odor between loads, as well as minimize bacterial growth in the residual water catch basin under the metal filter. While not perfect, this technique has helped minimize the stench after washing dishes soiled with egg yolk.

My overall impression is that Bosch engineers have designed a good overall DW, but it has some flaws that should be remedied.
