After the remodel crew left
Dishwashers are slid in and out for new flooring, a replaced sink, and countertop swaps more than people expect. Each time, hoses can kink, cables get pinched, and the unit may settle a few degrees off level. If E23 started the week the contractors finished, it is worth asking what was disturbed. A dishwasher that is not level can change how the door closes and how water settles in the tub, which matters to anything that senses either.
Meaning of E23
No single definition is confirmed for E23 on every Bertazzoni dishwasher. The timing of the first appearance is a stronger clue than the code, which is why this page is built around it.
What owners can look at
- Is the dishwasher level side to side and front to back, judged with a small bubble level on the door edge?
- Does the door close without rubbing the new flooring or countertop?
- Is the water valve open, and is there a drip at the connection?
- Does anything look strained, for example a hose pulled tight behind the unit?
Do not pull the unit out to look behind it. That repeats the same stress that may have caused the code and risks a leak from a loosened fitting.
Things a contractor may have changed
A new countertop with a thicker edge can push on the top of the dishwasher. Mounting brackets might have been left loose, so the machine shifts when the door opens. Flooring that is higher than the old floor can lift the front, tilting the tub. A call to the contractor can fill in these points quickly. Any one of these changes can strain a hose or cable without leaking, so a dry floor does not rule them out.
Why a technician is needed
If the physical checks look fine and E23 persists, the next step is testing the electrical connections and sensing inside the base and behind the front, which were possibly disturbed. That work is done with the power on, so it is out of bounds for owners.
The visit gives you a diagnosis first, then a written estimate, and no repair goes ahead without your approval. Mention the date of the remodel when you book, since it narrows the search and may point at a fix that belongs with the installer.
A quick history helps
List what work was done near the dishwasher, when, and by whom, including anything involving plumbing or electrical. A contractor who can tell us whether the unit was disconnected and reconnected, or simply slid forward, saves real diagnostic time on arrival. That history also helps separate a problem the remodel created from one that was already developing.

Frequently asked questions
If the code began right after the work and a hose or bracket was disturbed, the contractor is a fair first conversation.
It can change how the machine reads water and how the door closes, so leveling matters.
If there is no leak or trip, light use is fine until the visit.
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.
