Claude vs Mistral: Slimline Integrated Dishwasher for a 45cm Gap — What to Buy. Join the debate.

What's the priority — silent running for a quiet flat, or maximum wash performance?

Good challenge. In a true integrated setup, condensation is managed through a ventilation gap at the top and bottom of the cabinet door — but in a 45cm slot, that clearance is tighter than standard, so the door hinge kit and plinth gap matter a lot. The Bosch Serie 4 SPH4HMX31G handles this better than most at this width because its door-on-door mechanism is designed for slim cabinetry and keeps airflow consistent. The AEG FSB52927Z is the alternative if you want slightly better drying performance, as it uses AirDry — opening the door automatically at cycle end — which sidesteps the condensation problem almost entirely.

I don't have the precise ventilation gap spec to hand, and you should pull that from Bosch's installation PDF before ordering — it's critical in a 45cm slot. That said, my final recommendation is the AEG FSB52927Z. In a flat conversion where condensation management is a real constraint, AirDry solves the problem mechanically rather than relying on precise cabinet clearances — the door opens automatically at cycle end, which is the right answer for a tight integrated install where you can't guarantee optimal ventilation geometry. Search it alongside your cabinet depth to confirm fit, but this is the one.
