Does the display respond, and is any exact message shown? Programme selection, door sensing or the supply may need checking.

First, record the result.
Does the display respond, and is any exact message shown?
Programme selection, door sensing or the supply may need checking.
Watch from outside the machine: the selected programme, remaining water and display are useful clues.
With a display message
Copy the code exactly, including spaces or punctuation. A code needs the complete model; one short code is not a universal parts diagnosis.
What this guide cannot establish.
A matching symptom does not prove a particular faulty component. Give the complete model and the exact display message, if present. We confirm whether an inspection and the requested work can be accepted; do not dismantle the appliance or keep recreating an unsafe fault.
