The short answer
On a Fotile dishwasher that is leaving dishes dirty, the cause to suspect first is spray arms blocked or not turning freely, with weak circulation from the wash pump behind it. The ranking below is written for the tall-tub build with a third level, which you can confirm in seconds: a shallow cutlery tray across the top of the cabinet means a third spray feed and a taller stack of water to lift. Arms, filter, dispenser, loading and programme are owner work; anything under the sump is not.
What you observe
- One shelf clean and the other dirty — A sector problem, which only a spray path can produce.
- Greasy film that wipes off with a finger — Heat rather than mechanics: fats need temperature to move at all.
- White cloudiness on glassware — Mineral film if it clears with a weak acid, etching if it does not.
- Food deposits redeposited on the upturned items — Debris coming back out of the sump, which is a filter story.
- Dishes clean but soaking wet at the end — A drying complaint rather than a cleaning one, and rinse aid is the first thing to check.
- NEAR MISS — water standing in the sump at the end — That is a drainage fault, and the drainage page is the right one to read.
Causes, most likely first on this brand
- Spray arms blocked or not turning freely — Ranked first here: this is the cause that produces the classic pattern of one clean shelf and one dirty one, which no detergent or temperature problem ever does.
- Weak circulation from the wash pump — Second: if the arms turn freely, the filter is clean, the water is hot and the load is sane, then the remaining question is whether the machine is developing any pressure at all.
- A short cycle chosen for a heavy load — Third: an eco or rapid programme is a real programme with real limits.
- Loading that shadows the spray — Fourth: water travels in straight lines.
- Rinse aid empty — Fifth: rinse aid is what makes water sheet off rather than bead, and without it the load comes out spotted and wet even when it is perfectly clean.
- Filter and sump carrying old debris — Sixth: the wash water is recirculated, so the filter is the only thing standing between last night's debris and tonight's plates.
Check in this order, and why
- Spin each arm by hand and look through the jets — Seconds to do, and it is the only cause that produces one clean shelf and one dirty one.
- Listen for a strong rhythmic wash sound mid-cycle — A machine that sounds weak with everything else clean is a circulation question.
- Repeat the load on the longest hot programme — If it comes out clean, the programme was the limit rather than the machine.
What an owner can safely check
- Top up the rinse aid and check the detergent flap opens freely — Two reservoirs that fail quietly and change the result completely.
About 5 min
- Spin each spray arm by hand and clear any blocked jets — The fastest check on the list and the one that explains an uneven load.
Tools: cocktail stickAbout 10 min
- Run the kitchen tap hot, then start the longest hot programme — Tests temperature and programme length together, on one load.
About 10 min
- STOP HERE if the wash sounds weak with everything above clean — Circulation is a pump question and it sits behind the sump.
Before you open anything
Safety
Power off at the spur, water off at the valve, then open anything. Those two come first because the wiring and the plumbing in this cabinet run alongside each other. Leave the door latch alone: defeating it lets a hot cycle run with the door open. Bail the water out before you tip the machine forward, and treat anything in the sump as sharp until you have seen it.
When to call a technician
The line is the sump. Everything above it — arms, filter, dispenser, loading, programme — is owner work and costs nothing.

What this page does not cover
Written for Fotile dishwashers as a class, not for one family. No family-specific page for this brand and appliance is published here yet; where one exists for your unit it takes precedence over this page. Wiring colours, torque figures and part numbers are deliberately not here: they differ by family.
