The short answer
A machine that will not begin a cycle: on an IKEA dishwasher that is usually a supply that is not arriving, not a failed control board. Second, and worth checking in the same hour, is a closed supply stop. The top of that list is owner work; only the last cause needs a technician.
What you are looking at
- The panel is dark and nothing responds — No lights and no beep from any button.
- The panel lights but the cycle never begins — It accepts the selection and then waits.
- It beeps and refuses the start — An audible refusal rather than silence.
- NEAR MISS -- it runs but nothing gets clean — Running proves start; cleaning belongs on another page.
Causes, most likely first on this kind of unit
- The supply is not arriving — Dishwashers are usually fed from a switch under the sink or a dedicated breaker. A switched-off switch or a tripped breaker leaves a dark panel and no response. First here, because on an IKEA appliance on its mainstream OEM platform a machine fed through a switch under the sink loses its power to that switch more often than to anything else.
- The supply stop is closed — A machine that cannot fill will not advance, and on many controls that reads as a machine that will not start. The stop under the sink is often closed after other plumbing work. Ranked here because a machine waiting for water looks exactly like a machine that will not start.
- The door latch is not reporting closed — No dishwasher runs with the door unlatched. A latch that no longer engages, or a door held off by a tall item in the rack, leaves the panel lit and nothing happening. This rank, because a machine that thinks the door is open waits forever with the panel alive.
- The main board or its thermal fuse — A board with an open thermal fuse, or a failed relay, gives a dead or half-lit panel that no reset will cure. Diagnosis needs a meter behind the kick panel. Bottom of the list, deliberately: it is the one cause here that is not an owner repair, so it is last.
Check in this order, and why
- Check the switch under the sink and the breaker — A standard US household branch circuit is fifteen or twenty amps at one hundred twenty volts; confirm the switch and reset the breaker.
- Open the stop under the sink fully — Full-open the valve, then start a cycle and listen for water entering.
- Only after latch, supply and water are proven — A dead panel with a live circuit, or a machine that ignores every reset, is a service call.
What an owner can safely check
- Check the switch under the sink and reset the breaker — Both are outside the machine, and both are the commonest cause of a dark panel.
About 10 min
- Close the door slowly and listen for the latch — Clear anything in the top rack that holds the door off its catch.
About 5 min
- Open the supply stop fully and start a cycle — Listen for water within the first minute.
About 10 min
- STOP HERE -- the next step needs the kick panel off — Boards, fuses, latches and switches are technician work on a live circuit.
Before you open anything
Safety
Switch the dishwasher off at its breaker or the switch under the sink before any panel comes off, and close the supply valve before touching a fitting. Water in the sump can be scalding at the end of a cycle.
When to call a technician
Call once the filter, the spray arms, the drain path and the detergent have all been ruled out.

What this page does not cover
This page covers the IKEA dishwasher as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer -- go there first if your model is named. Deliberately not here: latch part numbers, board layouts, service-mode entry and the panel-removal order, all of which differ by family.
