The short answer
The useful thing to know about a Vezeni dishwasher with this symptom is which cause to try first. Here that is The door is not latching, and the one to try last is A thermal fuse that has opened. Everything near the top of the list is an owner check that costs nothing; the bottom of it is a service call.
What you actually observe
- Nothing at all when you press start — Either no power or no latch.
- The panel lights and nothing happens — The machine is waiting for a condition.
- One button on the panel does nothing — A worn membrane rather than a dead machine.
- NEAR MISS: it starts and stops with water in the tub — That is a drainage fault and it belongs on a different page.
Causes, most likely first on this build
- The door is not latching — A dishwasher will not start unless the latch proves the door is shut, and the latch is operated on every single cycle. Worn, or held off by a plate in the rack, it leaves a machine that will not begin. Ranked first on a Vezeni: a countertop unit sits in the warmest air in the kitchen, right beside the things that make the kitchen warm.
- The supply valve is closed — The isolating valve under the sink gets closed during other plumbing work and not reopened. Second here, because a hand-filled, hand-emptied unit depends on the owner's routine more than on any part inside it.
- A child lock or delay start is set — Both leave a panel that lights and a machine that does nothing, and both are set by accident with a long button press. Third, once the two above are clean: it is free, immediate, and it decides whether this is a fault at all.
- A thermal fuse that has opened — A one-shot fuse protects the control from an overheat, and when it opens the machine is completely inert. Last, and the reason the order above matters: it is the rarest cause and the only one that is not an owner fix on a unit this small.
Check in this order, and why
- Close the door firmly and listen for the latch — No latch, no start, on every machine.
- Check the isolating valve under the sink is open — Closed during other work and not reopened.
- Look for a lock or delay indicator on the panel — Cleared in seconds once you know it is set.
What an owner can safely check
- Check the tap adapter is fully seated and the drain hose is hooked properly over the sink — A countertop machine is coupled by hand for every wash, and that is the joint that leaks or fails to fill.
About 10 min
- Close the door firmly and listen for the latch to click home — It is the commonest reason a dishwasher will not begin a cycle.
About 5 min
- Find the switch under the worktop or the outlet in the cabinet and check it is on — Built-in machines are fed from a switch that is easy to knock off and easy to forget.
Tools: a torchAbout 10 min
- STOP HERE if power is present, the door latches and the panel is still dead — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Switch the machine off at the isolating switch under the worktop, or unplug it, before opening any panel, and shut the supply valve under the sink. A capacitor can hold a charge after the power is off.
When to call a technician
Call when the outlet or the switch under the worktop is proven live, the door latches, the supply valve is open and no lock or delay is set. A dead panel with live power is a control fault, and on an older machine the price of a panel is what decides repair against replacement.

What is deliberately not on this page
This page is written for the Vezeni dishwasher as a class, not for one family or model line. Where a family- or model-specific page exists for your machine it is linked above, and it is the more specific answer. Deliberately not here: error-code tables, pump and board part numbers and any plumbing specification for your installation.
