Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Drying — PureDry condensation, NO heating element
- Like all Bosch dishwashers, the 100 Series has NO exposed heating element — it dries by condensation (PureDry). So damp dishes, ESPECIALLY plastics, are largely normal, not a fault: plastic does not hold heat, so water does not evaporate off it the way it does off glass and ceramic. The upside is plastics can go on any rack without warping.
- Rinse aid is essential
- Because drying relies on water sheeting off the dishes, rinse aid is not optional on a Bosch — an empty or low rinse-aid tank is the number-one cause of wet dishes. Keep it filled and set the dosage up if plastics stay wet.
- Manual filter
- It has a manual filter at the tub floor (not a food grinder) that must be rinsed periodically — a clogged filter is the top cause of poor cleaning, film and odour, and of slow draining.

Exact questions
Questions that only have an answer for the Bosch 100 Series SHXM4AY55N dishwasher
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
Why are my dishes still wet in my Bosch 100 dishwasher?+
That is mostly normal for Bosch, which dries by condensation with no heating element. Plastics especially come out damp because they do not retain the heat that evaporates water off glass and ceramic. The single biggest fix is rinse aid — keep the tank filled and raise the dosage, because Bosch drying depends on water sheeting off the dishes. Opening the door for a while after the cycle also lets the remaining moisture escape.
