The short answer for the DC models
On the Acekool DC dishwasher models, water that will not leave the machine leads somewhere the brand-generic article does not put first — the sink plumbing itself is blocked. The brand-generic ordering opens instead with this: debris in the filter and the sump. It moves down behind the lead here, because the two codes in this family share a platform, so a cause that is real on one is real on both.
What you observe on these models
- Water comes back into the machine after it has drained — That is siphoning or a backflow, not a failure to pump.
- A pool of water in the bottom at the end of every cycle — Enough to cover the sump and the filter, and it does not go down on its own.
- The cycle finishes but the dishes are wet and smell — Dirty water sat on them for the last part of the programme.
- NEAR MISS — the machine will not start at all — No cycle means no drain; start at the will-not-start page instead.
Causes, most likely first on the DC family
- The sink plumbing itself is blocked — The machine shares its drain with the sink. Ranked first on the DC models.
- Debris in the filter and the sump — Labels, seeds, bones and broken glass collect exactly where the water leaves. Second.
- A drain hose hooked over a sink rather than plumbed in — A countertop machine pumps into open air over the edge of a sink. Third.
- The drain pump has failed — Every other item here is cheaper, faster and more often the answer, and a silent pump is the only real evidence for this one. Last, and that is the point of the order.
- Body: The spine for the DC family records two model codes that share their stem and differ only in what follows it, so the two behave as one platform for this fault. Where this departs from the brand-generic ordering: the cause that moves up on these models is this one — the sink plumbing itself is blocked — and the brand-generic lead moves down behind it.
Check in this order on the DC models, and why
- Listen at the start of the drain phase — First: A pump that hums without flow points at a blockage; silence points at power or at the pump itself.
- Ask what changed at the sink recently — Second: A new disposer, a new trap or a plumber at the sink is the single most predictive question on this list.
- Take the air gap cover off, where one is fitted — Third: It is a two-second check that is invisible from inside the machine.
Before you open anything
Safety
Power off at the breaker and water off at the valve, in that order, before anything comes apart — the capacitor stays charged after the switch and the sump stays full after the cycle. Put a towel down, wear gloves, and do not reach blind into a sump where a glass has broken. The door catch is never to be defeated.

When to call a technician
Call when the filter and sump are clean, the sink drains freely, the hose runs without a crush and has a high loop, and the machine still finishes with water in it — that puts the fault at the valve or the pump, both under the sump. Call rather than continue if a glass has broken in the machine and you can see fragments in the sump, because clearing those blind is how people get cut. On the DC models the line sits where the check stops being one you can make from outside the cabinet. On a countertop machine, weigh the repair against the machine: the labour to open one up is much the same as for a full-size machine and the machine is not.
