A photograph is useful for identification, but the model and approved part reference are needed to confirm a match. Similar-looking seals, elbows and controls can have different dimensions or operating requirements.
What the observation tells you
An online description such as universal should be checked against the manufacturer's compatibility information. Do not trim rubber, enlarge fixing holes or adapt electrical connections to fit a part that was not confirmed. The old component's wear can also make its shape misleading.
A useful next step
Give the supplier the full appliance reference and the part's location in the diagram. Keep the proposed replacement unused until compatibility is established.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
