Its type and the amount used are relevant observations, especially if a change coincides with poor clearance. The unit's permitted-use guidance remains the reference.
What the observation means
Do not infer that one brand is defective or that every soft paper is unsuitable. A drainage fault can also coincide with a product change.
A useful next step
Record the timing and avoid excessive loading. Stop further flushing if water does not clear. Do not run repeated comparisons with different paper products or treat a change of paper as proof that an unresolved pump fault has been repaired.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
