After the machine cleans itself
Many models run an automatic cleaning program that pushes water and a cleaning tablet through the brew area. The cycle ends, the display returns, and the first drink fails with E33. The code is model-dependent, so it cannot be tied to one part, yet the connection to cleaning is a lead. The brew area is the chamber where coffee is pressed and water passes through, and it is the part of the machine most exposed to cleaning solution.
What cleaning leaves behind
Water, dissolved cleaner and loosened oils all remain in the brew area for a while. Tablet fragments that did not dissolve can sit in passages. If the program was interrupted or the rinse step was skipped, more of this stays behind. Residue can affect moving parts and the sensors that watch them. A position sensor confirms that the brew unit reached its stop, and a film on it or on the moving part can make that confirmation fail.
Questions worth answering
- Did the program run to the very end?
- Was a tablet used, and was it the type the manual names?
- Did a rinse follow, and was the tank refilled?
- How much time passed before the first drink?
A slow Sunday
Picture a cleaning program started on Sunday evening, interrupted when someone needed the kitchen. On Monday morning the machine, half way through the routine, refuses to brew. Running the program again from the start, with fresh water, is a reasonable first step.
What a technician examines
The brew group’s movement, the sensors reporting its position, and the valves and seals in contact with cleaning solution. Dried residue on contacts may be removed during the visit.
Safe checks
- Empty and refill the tank with fresh water.
- Run the rinse function again and let it finish.
- Empty the drip tray and the grounds container, which often hold cleaning liquid.
- Wait half an hour, then try one cup.
Avoid trying other cleaning agents. A mix of products can cause residues that are hard to remove.
Hard and soft water after cleaning
In hard-water areas the cleaning program also dissolves some scale, and loosened flakes can travel to places they were not before. In soft-water areas this matters less. Mention your water type, since it helps judge whether debris could be involved.
When to book
If E33 returns after a clean program and a complete rinse, the brew area needs inspection. Reaching it means taking parts apart that are not meant for owners. The visit gives you a diagnosis, a written estimate, and no repair until you approve.
Frequently asked questions
Rarely. Most cases involve an unfinished rinse or residue, but a code that stays needs a diagnosis.
Once, from the beginning with fresh water, is reasonable. Repeated runs add chemicals without fixing a fault.
The one your owner manual names. Other products may leave residues or damage seals.
It collects the cleaning liquid and may be near full or misplaced after the program. An overfilled tray is easy to overlook.
Model compatibility: Bertazzoni reuses codes across series and model years, so E33 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
