pressure-sensor problem
Isolate the appliance when safe. clean accessible filters as the model manual permits, run no repeated cycles, and arrange service if the code remains Do not open fixed panels or test live circuits.
Typical symptoms
Fault area and what the code does not prove
Separate the manufacturer-defined condition from components that still need exact-model diagnosis.
Safe next steps
- 1Confirm the exact AEG Dishwasher i40 model and displayed code before taking action.
- 2Keep the appliance in a safe state and use only the external checks named in the official source.
- 3If the condition remains, stop and arrange qualified service; do not open panels or bypass a safety device.
Step-by-step diagnosis
- 1Photograph the complete i40 display before changing controls or removing power
- 2Confirm that the full model number is covered by this scope: AEG dishwashers covered by the linked UK support article
- 3Confirm that the observed condition matches the published meaning: pressure-sensor problem
- 4Published check — clean accessible filters as the model manual permits, run no repeated cycles, and arrange service if the code remains
- 5Stop at the published service boundary after these actions
- 6do not add a restart or test cycle that AEG does not specify for i40
- 7Published check — Give service the i40 photo, full model and serial number, when it appeared, and the result of every published external check
- 8Stop at the published service boundary after these actions; do not add a restart or test cycle that AEG does not specify for i40
Service-safe actions
- 1clean accessible filters as the model manual permits, run no repeated cycles, and arrange service if the code remains
- 2Give service the i40 photo, full model and serial number, when it appeared, and the result of every published external check
Repair planning
i40 cost planning: The source-listed external check costs €0. A qualified sensor-system diagnosis is generally planned within €90–€220 before any model-specific part is approved.
i40 time plan: 10–20 minutes for the documented i40 external check; allow 30–90 minutes for measured sensor, wiring, and control diagnosis.

i40 parts decision: i40 describes pressure-sensor problem; it does not prove the sensor itself has failed. A blocked path, connector, wiring, control input, or the measured condition can produce the same reported area.
What not to do
- Do not bridge, heat, cool, wet, or electrically probe a sensor to clear i40
- Do not replace a sensor until its circuit and the condition it measures have been checked
- Do not run an extra test cycle after the source tells you to stop or arrange service for i40
Preventive maintenance
- 1Follow the exact AEG maintenance schedule for the dishwasher and keep the model, serial number, and service history available
- 2If i40 begins recurring despite the documented maintenance, stop repeating the same action and request exact-model diagnosis

AEG identifies it as pressure-sensor problem.
Which action is actually supported for i40?
clean accessible filters as the model manual permits, run no repeated cycles, and arrange service if the code remains; Give service the i40 photo, full model and serial number, when it appeared, and the result of every published external check.
Can I run another test after i40?
Not unless the official procedure above explicitly includes it. Complete the safe external actions, then keep the appliance stopped at the service boundary.
Does i40 prove which part failed?
No. It identifies “pressure-sensor problem”; parts are selected only after the exact model and failed function are confirmed.
What information should accompany a service request?
The i40 photo, full model and serial number, the operating stage when it appeared, and the result of each published check.
