Read the controls before resetting anything
Delay-start, control lock and a paused programme can look like a no-start fault. Read the symbols in the instructions for the exact model. On some integrated appliances the controls sit on the top edge and the start sequence includes closing the door after choosing a programme; do not assume the process matches a previous dishwasher.
Photograph an error or flashing-light sequence before cancelling it. If the display is dark, note whether there has been a power interruption and whether other household appliances are affected. Do not open electrical covers, pull out an integrated unit or reset a circuit repeatedly to see if it will stay on.
Check the closing space, not the latch mechanism
With the machine stopped and safe to approach, look for a utensil, rack or tall plate preventing normal closure. A rack that is not fully seated can leave the door apparently closed without a reliable latch signal. Reposition only ordinary loading items; stop if the door needs force or feels misaligned.
A recent kitchen alteration or replacement decorative panel is important to mention. Do not adjust hinges, defeat the door switch or hold the door shut to make a cycle run. The appliance must close normally and remain secure without pressure from a person.
A clear account of the controls, latch and first sounds helps our dishwasher repair enquiry service.
A drain sound is not necessarily a wash starting
Many dishwashers briefly drain at the beginning of a programme. If you hear a pump and then silence, record that sequence and whether any water enters afterwards. Continuous pumping with an alert is a different symptom from no power. Neither sound alone identifies a failed pump or inlet valve.
Check only a familiar, readily accessible supply tap if there is no leak or electrical hazard. Do not disconnect hoses or tilt the dishwasher to clear a warning. Water detected in a concealed area may be triggering protection; clearing the symptom without finding the cause can permit another leak.
