The short answer
On a Unique dishwasher, a dishwasher that will not start is usually being stopped rather than broken: a door that is not quite latched, a control lock nobody set on purpose, or a dead outlet under the sink. All three are free to check and between them they account for most of these calls. When a machine may be running on a supply that is not a standard house circuit, the supply itself has to be cleared before any part is suspected.
What you are actually seeing
- Nothing at all happens when you press start — No display, no sound, no lights.
- The display lights but the cycle never begins — Power is present, so the fault is a lock, a latch or a supply.
- It starts and then stops within a minute — It is starting fine; something it needs is missing, and that is usually water.
- NEAR MISS — it runs but the dishes come out dirty — That is a wash performance fault and it has its own page.
Causes, most likely first on this dishwasher
- Door latch or door switch not making contact — Ranked first on Unique: the latch and the door switch are the parts a bought-in platform shares across every model, and they are also the parts used twice a day. On this one, remember that the supply may not be a standard house circuit, so clear the supply before suspecting a part.
- No power at the machine — a tripped breaker, a dead outlet or a switched receptacle — Second: the outlet under the sink is often shared with a waste disposer and sits where leaks happen, so it is the first electrical suspect.
- It starts but finds no water and stops again — Third: a machine that starts and then stops early with no water is not a starting fault at all, but it gets reported as one.
- Thermal fuse or control board — Last, and that is the point of the order: it needs the fascia or the lower panel off and a meter, which is exactly where an owner check ends.
Check in this order, and why
- First — push the door firmly shut and listen for the latch to click home — If it starts after a firm push, the latch or its alignment is the fault and nothing else on this list matters.
- Then — check the breaker, and check the outlet under the sink with something else — A lamp in that outlet answers the question in a minute and costs nothing.
- Only then — only after door, lock, power, water and float are all clear — Everything above is free, and a control fault cannot be confirmed without instruments, which is why it comes after everything above it.
What an owner can safely check
- Close the door firmly and try again, then look at the latch plate — Push the door until the latch clicks rather than letting it swing shut. Check nothing on the top rack is holding it off the seal.
About 5 min
- Open the supply valve fully and check the inlet hose is not kinked — Trace the hose from the valve to the machine and straighten any tight bend behind the cabinet.
Tools: torchAbout 10 min
- STOP before testing anything electrical with the power on — The checks above are all cold checks. Anything that needs power applied is where an owner check ends.
Before you open anything
Safety
Switch the machine off at its breaker before you reach behind it or take the lower panel off. The outlet under a sink is a wet location, so treat a tripped protective device as a message rather than a nuisance — a device that trips again after a reset is telling you something is wrong with the circuit or the machine. Do not defeat a door latch or hold a door switch closed to make a machine run: the switch stops the wash pump while the door is open.
When it stops being an owner job
Call once the door, the control lock, the outlet, the supply valve and the float have all been cleared and the machine still does nothing. At that point the fault is behind the fascia or in the base, and both need the power off and a meter.

This page is written for the Unique dishwasher as a class, not for one family or one model line. Where a family-specific page exists for your unit it is linked above and it is the more specific answer. Deliberately not here: part numbers, wiring colours, torque figures and any measured value, all of which differ by family.
