The short answer
Dirty dishes are a water-and-chemistry problem far more often than a broken machine. The ranking here begins with incoming water not hot enough.
What you observe
- Gritty deposits on the dishes after a full cycle — Debris is being recirculated, which points at the filter or the sump.
- A cloudy white film on glassware — Hard-water scale or too little rinse aid rather than dirt.
- Food baked onto the upper rack only — The upper spray arm is not getting water or is not turning.
- NEAR MISS — the machine will not run a cycle at all — Then this is the wrong page; start with the wont-start ranking.
Causes, most likely first on a Shenzhen Eanxa Technology Co., Ltd dishwasher
- Incoming water not hot enough — A dishwasher relies on the water it is given; a long pipe run or a low heater setting starves it. Ranked first on a Shenzhen Eanxa Technology Co., Ltd dishwasher: it is free to test and it explains dishes that are both dirty and wet at the end of a cycle.
- Filter clogged — A filter nobody has cleaned turns every cycle into a wash in dirty water.
- Inlet screen or a low fill — A silted screen at the fill valve lowers the water level, and a machine short of water cannot wash.
- Spray arms blocked or not turning — An arm fouled by a tall item cannot turn, so everything above or below it comes out dirty.
Check in this order, and why
- Run the kitchen tap hot before starting a cycle and see whether the result changes — Time how long the tap takes to run hot: a long run is the cause.
- Lift the filter out of the sump and look at it — A visible mat of debris is both the diagnosis and the job.
- Open the door mid-cycle and look at the water level in the sump — Do this carefully: the water is hot.
What an owner can safely check
- Run the kitchen hot tap until it is properly hot, then start the cycle immediately — It fills the machine with hot water from the first moment rather than the last, and the difference is usually visible.
About 10 min
- Twist the filter assembly out, rinse both parts under a hot tap with a brush, and refit it until it locks — A filter left unlocked lets debris straight into the pump, so check it seats and turns home.
Tools: washing-up brush, gloveAbout 15 min
- STOP HERE if the next step needs a panel off or a meter on live terminals — That is where the owner checks end and a service call begins, whatever the ranking says.
Before you open anything
Safety
Power off at the breaker or isolation switch before any hand goes into the sump, and give a capacitor time to bleed down. Assume there is glass in the water: glove and torch, never bare hands. The water supply valve gets closed before a hose is loosened. Keep weight off the open door, and let the machine cool before reaching in after a hot cycle — the water and the heater both stay hot for a while.
When to call a technician
Everything in the tub is owner work: filter, arms, dispenser, loading and rinse aid. The wash pump, the inlet valve and the heating element are not, and a machine that fills short after all of the above needs a technician. Expect no manufacturer service network: judge the repair on the cost of the part alone, and treat anything requiring a control board as a replace decision.

What this page does not cover
This page covers the Shenzhen Eanxa Technology Co., Ltd dishwasher as a class, not one family or model line. Where a family- or model-specific page exists for your unit it is linked above and it is the better answer — read it first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, all of which differ between families under one nameplate.
