Miele Heat pump tumble dryer: ,  and  lights persist after cleaning — Deep clogging or heat exchanger issue

What does , ,  persistent mean?

If the , , and  indicators continue to flash after thorough cleaning and a programme is terminated again, it suggests a deeper clog in the system or an issue with the heat exchanger.

• Deeper level clogging of the plinth filter
• Clogged heat exchanger
• Insufficient cleaning of residues
