What the F26 Fault Code Means
The F26 fault code indicates that the boiling protection system has triggered. Miele dishwashers include a boiling protection feature to prevent water from reaching boiling point during a cycle. When this protection activates unexpectedly, or when the associated sensor or relay detects an abnormal condition, the machine stops the programme and displays F26. This is a technical fault that requires professional attention.
Common Reasons This Fault Appears
Faulty temperature sensor
A fault with the NTC temperature sensor can cause incorrect temperature readings that trigger the boiling protection system.
Heater relay fault
A fault with the heater relay can cause the heating element to overheat, triggering the boiling protection.
Control board fault
An issue with the main electronic control module can cause incorrect temperature management and trigger this fault.
Wiring fault
A loose or damaged electrical connection in the heating or sensor circuit can cause this fault to appear.
Safe Checks You Can Try
