Error codeE3
ApplianceDishwasher
Quick answer
E3 is a heating timeout on Bertazzoni DW24PR and DW18PR dishwashers.
Model compatibility: Bertazzoni reuses codes across series and model years, so E3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E3 means the defined temperature was not reached within 90 minutes of heating.
Two Bertazzoni manuals, DW24PR and DW18PR, assign E3 (E03 in some listings) to a heating timeout: if the dishwasher cannot bring the water up to the defined temperature after 90 minutes, it warns with this code.
Service checklist from the manual
The heater, which raises the temperature of the wash water
The thermistor, a sensor that changes resistance as it warms
The PCB, the board in charge of heating that takes the sensor’s signal
They are given in that order and with no extra detail, which is everything the source says on this code.
A caution about one remark
The error table carries the wording “only appeared in the factory mode” beside this entry. Its placement does not settle whether E3 or a nearby row is meant. An E3 during a normal cycle should be taken as genuine.
For owners
The manual lists no owner steps. Cancel the cycle and take the plug out before anyone inspects the machine, with hot water and a powered heater in mind. Also remember how the dishes felt at the end.
Models
The entry appears for the DW24PR and DW18PR only. The DW24XV table has other codes and no E3.
For a Bertazzoni dishwasher in Los Angeles that gives E3, call (310) 987-4514. Describe how the dishes looked at the end of the cycle; the dishwasher repair page has more.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
