What this code means

Symptoms you may notice
- The dishwasher displays F3E4 and temperatures seem off
- F3E4 appears intermittently during operation
- The dishwasher behaves inconsistently with F3E4 shown
Possible causes
- A temperature sensor reading out of range
- A wiring or connection issue to the sensor

Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
- Confirm nothing is blocking internal vents or airflow
- Note the actual behavior or temperatures if measurable
- Perform a manufacturer-approved restart
- Share freezer vs fridge temperatures, or wash/heat symptoms, when you book service
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.
What not to attempt
- Do not open internal panels or access high-voltage components
- Do not bypass door locks, safety switches or interlocks
When to call a technician
When F3E4 keeps returning, stop DIY inside the cabinet and schedule Artisan Repair — bring photos of the display and rating label.
