The short answer
On a Haier dishwasher, a machine that refuses to begin a cycle most often comes down to a door latch not making its switch. Haier dishwashers use a compact filtered sump with a small drain pump, so debris that a larger machine tolerates will stop this one. The first check below needs no tools, and the list stops where a meter on live terminals begins.
What you observe
- The panel is completely dark — No supply, or nothing downstream of it, reaching the control.
- The panel lights but pressing start does nothing — Power is present, so the fault is a permission rather than a supply.
- It beeps or flashes and cancels itself — The machine is refusing for a reason it is trying to tell you.
- NEAR MISS — it starts but leaves water in the bottom — That is a drainage fault and a different page.
Causes, most likely first on a Haier dishwasher
- Door latch not making its switch — Ranked first here: a lighter door and a plastic latch go out of alignment quickly, so the latch is the first suspect on this platform.
- Tripped breaker or dead socket — Ranked second: a machine with no supply is indistinguishable from a broken one until you check.
- Control lock or delay start set — Last on this list: a locked or delayed control refuses everything and gives almost no sign why.
Check in this order, and why
- Close the door firmly and listen for the latch click — A weak or missing click is the fault. First: likeliest cause, least effort.
- Check the breaker and any switch under the sink — A standard US household branch circuit is 15 A or 20 A at 120 V; a large appliance circuit is typically 30 A or higher at 240 V. Second: it separates the next two causes.
- Look for a small padlock or delay symbol on the display — Usually cleared by pressing and holding one button. Third: only once the checks above are clean.
What an owner can safely check
- Press the door closed firmly and listen for a positive click — Many no-start calls end here.
Tools: noneAbout 5 min
- Check nothing in the racks is holding the door open a fraction — A handle or a tall item is enough.
Tools: noneAbout 5 min
- Switch the breaker fully off and back on, and check the sink-cabinet switch — A half-tripped breaker looks closed but is not.
Tools: noneAbout 10 min
- Press and hold the lock button, then clear any delay setting — Costs nothing and resolves a real share of no-start calls.
Tools: noneAbout 5 min
- STOP HERE if the next step needs a meter on live terminals — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off.
When to call a technician
Call once the door latch, the supply and any control lock are all proven good, because everything after that is a live-terminal test in a wet cabinet. Call immediately if the machine trips the breaker when you reset it, or if you smell hot insulation.

What this page does not cover
This page covers Haier dishwashers as a class, not one family or model line. It reasons from how Haier builds this appliance — enough to rank the causes, not enough for wiring colours, torque figures or part numbers, which differ by family. Where a model-specific page exists it is linked here and is the better answer; this class page has no such child yet, so nothing is withheld by omission.
