The short answer
Most control complaints on an EdgeStar compact dishwasher are settings rather than faults. Delay start, child lock and demo mode each produce a machine that lights up and refuses to work, and each is set by accident more often than any board fails. Establish which of those is set, then look at whether the machine can prove water and a latched door, and only then at the electronics. What you have is a roll-around portable that is wheeled to the sink, coupled, run, and wheeled away again.
What you are seeing
- A code or symbol appears that is not explained on the machine
- The panel lights but will not accept a cycle selection
- Buttons respond intermittently or respond to the wrong press
- If the machine simply does nothing at all, the will-not-start page is the right one — This points at a different fault; the page named above covers it.
Most likely causes on a compact portable dishwasher, in order
- A mode that was set by accident — first, because child lock, delay start and demo mode all present as a control fault, all are entered with a long press that is easy to make, and none of them costs anything to clear
- The machine unplugged and moved between cycles — a portable loses power every time it is put away, so a control returning to defaults or holding a stale state is ordinary behaviour on this form and not evidence of a failure
- Fill or drain not proven, reported as a code — a compact machine spends most of its error vocabulary on water, so a code is far more likely to be describing the tap, the tank or the drain hose than describing itself
- Moisture behind the membrane panel — a countertop panel sits directly above a steam vent, so condensation gets behind the membrane and produces exactly the intermittent and wrong-button behaviour owners describe
What to check, and why in this order
- Let the machine sit connected and powered for a moment before selecting a cycle — A portable is powered up cold at the start of every use
- Photograph the display exactly as it is before you touch anything — A power cycle erases the only evidence you have
- Clear every mode you can reach — Cancel any delay, release any child lock — before assuming a fault. This is second because it resolves a large share of these at no cost
Step by step
- Photograph the panel and any code, and photograph the rating plate on the back or the door edge. — Time: a minute.
Tools: a phone
- Plug in, connect the water, and let the machine sit powered for a moment before selecting a cycle. — Time: a minute.
- Press and hold each lock or delay button in turn according to the machine markings to clear anything that was set. — Time: several minutes.
- Open the tap fully or fill the tank, close the door firmly until the latch engages, and try the shortest cycle. — Time: several minutes.
Before you start: safety
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never spray a cleaner directly at the control panel — spray a cloth. Water behind a membrane is the cause of exactly the symptoms on this page, and on a mains appliance sitting on a worktop it is also an electrical hazard.
When to stop and call a technician
Call for service when a code returns immediately after a full power cycle with the tap open and the door latched, when the panel is dead while the machine has proven power, or when the control reports a sensor fault. Fitting a board to fix a water fault changes nothing.

What this page does not cover
This is generalized information: it covers EdgeStar dishwashers as a class, not one family or model. It does not carry your model's error-code table, wiring, part numbers, capacities or ambient range — those are on the rating plate and in the documentation, which are the authority wherever they disagree with this page. It leads with one form, the roll-around portable that is wheeled to the sink, coupled, run, and wheeled away again, and flags where the others diverge. Any family- or model-specific page is reached from the brand hub below, and takes precedence over this one. Pages this one hands down to: Common EdgeStar Dishwasher Problems (edgestar-dishwasher-problems).
