Begin with the seal
If E23 appears, the simplest place to look is where the door meets the cabinet. A gasket coated in dried syrup, a crumb trapped in a fold, or a corner that has curled away from the frame can all let the control believe the door is open. The control only knows what the door switch reports, so a seal problem and a switch problem can produce the same code, which is why cleaning comes first.
Moments people connect to it
The code shows up after a child’s snack spilled on the door shelf, after a deep clean that left the gasket damp, or after the door was forced shut against an overfilled bin. In coastal homes salt-laden air leaves a gritty film on rubber seals that makes them stiffen with time.
A five-minute routine
- Wipe the gasket on both sides with a damp soft cloth.
- Use a cotton swab for the corners and folds.
- Dry fully and close the door slowly.
- Check that each door bin sits flat and the door swings freely.
What to look for after cleaning
The door should close with a soft pull of the magnets and stay shut when released from an inch away. The interior light should go out right away. If the gasket remains wavy or a corner will not seat, a replacement is needed, and that is quick work for a technician.
If the code remains
Then the door switch itself, its wiring or the control input is the next suspect. These sit behind trim pieces and are checked with a meter. The technician confirms which one is responsible before anything is changed.
Seasonal note
Seals tighten when cold and soften when the kitchen warms, so a door that fails in the afternoon but works at night often points to a gasket that has aged rather than a failed switch. Noting the time of day when the code appears is worth the effort, because it separates a conditions problem from a part that has already failed.
Cost of ignoring
An imperfect seal brings in moisture and frost, which makes the compressor run longer. Attending to it within a few weeks keeps the repair small.
Replacing versus repairing
A cleaned gasket that still gaps is past saving, and a replacement is a normal part with a straightforward fit. A technician can also adjust door alignment during the same visit, so the new seal sits properly from day one and does not wear unevenly at the corners.
Frequently asked questions
Mild dish soap and warm water are enough. Strong solvents can dry out the rubber.
A warmer kitchen softens an aging gasket and lets it gap. That detail is useful to share.
Gentle warming from the room may not help. A replacement gasket is the usual fix.
Dry it fully before closing the door so it does not stick or freeze.
Model compatibility: Bertazzoni reuses codes across series and model years, so E23 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
