No. Suitability must be confirmed, and sealed refrigerant-circuit work is excluded. A heat-pump washer-dryer can have faults outside that boundary as well as within it.
Understanding this situation
The symptom alone does not establish which system needs work. A filter reminder, door issue and sealed-system problem are different enquiries, so a general not-drying description needs the model and observed details.
A useful next step
Provide the complete reference and programme result before arranging a visit. Do not open the refrigerant system or add refrigerant. The team can explain whether the proposed assessment falls within its service scope.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
