A symptom does not reliably identify the required component. Buying several likely parts can create expense without resolving compatibility, diagnosis or whether fitting is appropriate.
Understanding this situation
Two washers with similar names may use different versions, and a visible result can have more than one cause. A previous online answer is useful background only when it is clearly distinguished from confirmed findings.
A useful next step
Start with the full model, symptom and any existing report. Agree identification and work scope before ordering a replacement. If you already own a part, provide its details without assuming that it can or should be fitted.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
