The short answer
A door that does not seal is a continuous load on the whole cabinet, and it shows up as condensation and constant running long before it shows up as spoiled food. This is a European-built domestic appliance from a full line with an authorised service network, and it reports its own faults: the control watches its sensors and usually puts a code or a flashing pattern on the display before the owner notices anything, so reading what it is telling you comes before opening it. That is why "cabinet not level, so the door will not self-close" heads the ranking on this page, while "hinge or closer hardware worn" sits at the bottom of it. In a built-in or integrated installation the machine is boxed in, and that changes the answer: fixed clearances and a carcass that transmits vibration move the enclosure ahead of anything inside the appliance.
What you are actually seeing
- The door swings back open unless it is pushed
- Condensation or frost on the inner frame around the gasket
- A gasket that is torn, hardened or standing away from the cabinet
- Not this fault: the cabinet is warm despite a door that closes and grips — Means: a cooling failure — See: bosch-refrigerator-cooling-failure
- Not this fault: water is on the floor rather than at the frame — Means: a drain fault — See: bosch-refrigerator-water-leak
Likely causes, most likely first
- Cabinet not level, so the door will not self-close — Why here: first because it is the most common cause, it is free to correct, and every other door symptom follows from it — Confirmed by: the door stays wherever it is left instead of easing shut, and the cabinet rocks
- Door out of alignment on its hinges — Why here: ranks here because the gap is visible and adjustable, and a misaligned door destroys a new gasket in months — Confirmed by: the gap is uneven top to bottom, or the doors of a two-door cabinet no longer line up
- Overloaded door bins or shelves fouling the frame — Why here: a self-inflicted cause that is instantly reversible, which is why it belongs above any part failure — Confirmed by: the door closes cleanly once the bins are emptied, or an item is visibly catching
Check in this order
- Check the cabinet is level and slightly lower at the front — Because: a door that will not self-close is usually a cabinet problem, not a door problem
- Run a sheet of paper round the whole gasket — Because: it locates the failing section instead of condemning the whole seal
- Empty the door bins and try again — Because: load and fouling are free to eliminate and account for a real share of these complaints
Owner checks, in order
- Close a sheet of paper in the door and pull it out; repeat at several points around all four sides and note where it slides out freely — Tools: a sheet of paper — Time: a few minutes
- Check the cabinet with a level side to side and front to back, and adjust the feet until the door eases shut on its own — Tools: a spirit level, an adjustable wrench — Time: roughly half an hour
- Wash the gasket and the frame it seats against with warm soapy water, dry it, and re-test with the paper — Tools: a cloth, warm soapy water — Time: roughly half an hour
- Empty the door bins, close the door and watch for anything catching on the frame or a shelf — Tools: none — Time: a few minutes
- Stop condition: Stop before any test that would put a meter on live terminals.
Safety before you start
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A refrigerator is heavy and top-heavy on its castors. Never work with your hands behind a cabinet that is not chocked, and never tip one alone. The sealed refrigerant circuit is not owner-serviceable. Do not cut, bend or braze any tube, and do not attempt to add refrigerant.
When to call a technician
the gasket is split, or fails the paper test after cleaning and reshaping the door gap is uneven and does not correct with levelling the hinge has visible play or the door drops when opened
an authorised service network and a published parts catalogue exist for this brand, so a part identified from the model number can be ordered without guesswork

What this page does not cover
This page is generalized across every refrigerator sold under the Bosch name; it does not cover a specific family, model or serial range, and it carries no part number for your unit. This page ranks the same fault for a built-in or integrated installation, where a cabinet enclosure, a custom door panel and fixed clearances change which causes come first. Where a page exists for a narrower scope than this one it is linked below, and it takes precedence over anything written here.
