How it shows up ## What people describe when they call - “A tablet or powder still sitting in the cup” - “Dishes washed but not properly clean” - “It happens on some loads and not others” In more detail ## About Fisher & Paykel detergent still in the dispenser after a cycle ### The fastest diagnosis is the code Look at what is directly above the dispenser when you load it. A dish or a lid leaning over the cover will stop it opening, and it is the cause we find most. Then dry the dispenser cup with a cloth before putting the next tablet in — moisture in the cup before the tablet goes in makes it stick to the bottom and stay there. ### Why this is the maker’s most-linked article Because it is common, because it looks like a broken appliance, and because it usually is not one. Of the causes this maker publishes, **three are free**: a dish over the cover, a wet cup, and a cycle too short to dissolve a tablet. Only the fourth is a part. ### What a drawer changes A DishDrawer has a smaller wash chamber than a conventional dishwasher and it is loaded from above, so a plate that overhangs the dispenser is easier to create and harder to see. It also means detergent quantity matters more — the maker’s own guidance for these is a teaspoon at most, and too much produces foam rather than cleaner dishes. ### When it is worth a call When it happens on every cycle, with a dry cup, a clear cover and a full-length program. At that point the cover release or the heating side is the answer, and both are ordinary repairs. This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about fisher & Paykel detergent still in the dispenser after a cycle It can help if the problem is dissolving rather than the cover. Powder starts dissolving immediately and does not depend on a tablet breaking down; on a short program in cooler water that is a real difference. It is worth trying before spending anything, and it costs nothing to test. Then compare how the two are loaded before assuming a part. Each drawer has its own dispenser and its own wash system, so a difference between them is real — but the commonest reason one drawer does it and the other does not is that one of them gets the big plates. That is a different page: the detergent went in and the wash did not do its job. Spray arm, filter and water temperature, in that order — see “dishes coming out dirty”.
