The short answer
Read the console first - a control lock or delay start explains a great many of these. Then close the door firmly and try again, then check the supply valve, then the outlet or spur. A control board is the least likely cause and the only one that is not an owner check.
What you observe
- Lights on the console but nothing happens — The machine is awake and refusing.
- A lock symbol or a message you do not recognise — Very often a control lock or a delay start.
- A completely dark console — A supply question rather than a permission one.
- It starts only if the door is pressed firmly — A latch that is barely confirming.
- NEAR MISS - a quiet pause before the first fill — Many programmes sense the load before filling.
Causes, most likely first on this brand
- A control lock or delay start set — First. Both leave a lit but unresponsive machine, and both clear from the console in seconds once you know what you are looking at.
- A door latch that will not confirm — Second. The machine tests the latch before committing, and a worn catch means it never gets confirmation.
- A closed or restricted supply valve — Third. A machine that cannot fill abandons the cycle, and a valve closed for work under the sink is rarely reopened.
- No power at the outlet or spur — First when the console is dark. Kitchen circuits are shared and a trip caused by something else takes the dishwasher with it.
- A control board or wiring fault — Last. Uncommon, not an owner repair, and convincingly imitated by everything above.
Check in this order, and why
- Read the console properly — A lock or a delay is the commonest answer and costs nothing.
- Decide whether the console lights at all — That question splits this list in half.
- Press the door firmly shut and start again — If it now runs, the latch is the fault.
- Check the supply valve under the sink — Closed valves are the commonest forgotten step after plumbing work.
What an owner can safely check
- Read and clear the console — Look for a lock symbol, a delay start or a programme left selected.
About 10 min
- Close the door firmly and start a short cycle — Push the door in at the latch as you press start.
About 10 min
- Open the supply valve fully — Check the valve under the sink that serves the machine.
About 10 min
- Check the outlet or switched spur — Test with another appliance, and reset the breaker once only.
About 15 min
- STOP HERE if the console stays dark on a known-good supply — That is an electrical fault.
Before you open anything
Safety
Switch the dishwasher off at its breaker before removing any panel - a capacitor can hold a charge after the power is off. Never tape or wedge the door latch to persuade the machine to start, because that interlock keeps the door shut during a hot cycle. Close the supply valve before disturbing a hose, and do not repeatedly reset a breaker that trips when the machine is switched on.
When to call a technician
Call when the console shows no lock or delay, the door confirms with firm pressure, the supply valve is open, the outlet is proven good and the machine still will not start. Call without further testing if it trips the breaker when switched on or you smell hot insulation. Note any code the console displays, because that is information a technician can use directly.

What this page does not cover
This page covers the Cafe freestanding and slide-in dishwashers, which show their status on a visible front console. The panel-ready integrated machines hide their controls on the top edge of the door and are covered on the sibling page linked below. Deliberately absent: error codes, board and latch part identifiers, circuit ratings and service-mode sequences.
