Miele Dishwasher Error Code F25 and F26
Miele dishwasher error codes F25 and F26 indicate temperature-related issues within your appliance’s heating system. These errors often occur when components responsible for heating malfunction, affecting the dishwasher’s ability to reach or maintain the correct temperature for effective cleaning.
What Do Error Codes F25 and F26 Mean?
Both F25 and F26 signal problems in the dishwasher’s heating circuit. Specifically, the heater relay, heat pressure switch, and heating element work together to regulate water temperature.
