Use a phone camera or mirror from a safe accessible position while the appliance is unused. Do not twist the hanging unit, pull pipes aside or place yourself beneath an insecure mounting to obtain a clearer image.
What the observation tells you
Take one photograph showing the whole accessible label and another wider view of the appliance. A close image may crop out the model suffix or electrical details needed to identify the correct version. Keep wet electrical areas untouched.
A useful next step
If the label cannot be reached safely, explain that when booking and provide any purchase paperwork. Identification can be completed during an assessment without risking damage merely for a photograph.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
