The short answer
A Dreame compact dishwasher smells because water is standing somewhere it should not be. On this class the usual places are the small sump filter, the folds of the door gasket, the loop in the drain hose and — on tank-fill models — the fill tank itself. All four are owner jobs, and none of them is fixed by a stronger detergent. What you have is a tank-fill countertop machine that carries its own water rather than staying coupled to the tap. This page is ordered for the second pass: the obvious fix was tried and the fault returned, so the ranking puts the causes behind a recurring or intermittent fault above the ones behind a permanent one.
What you are seeing
- A stale or sour smell when the door is opened
- A visible grey or pink film in the sump or around the filter
- A smell that is strongest at the door gasket
- If water is standing in the base at the end of a cycle, the drainage page is the primary and the smell is a symptom — This points at a different fault; the page named above covers it.
Most likely causes on a countertop dishwasher, in order
- Water left standing in the fill tank — a tank left full between washes holds room-temperature water in the dark for days, and it is the single most productive place on this form for a smell or a film to start
- Standing water in the drain hose loop — a hose that loops over a sink lip holds water in the bend permanently, and in warm weather that water is what you can smell rather than anything inside the machine
- The door gasket and the underside of the door lip — the second reservoir: soft folds hold water and food, they are never reached by the wash, and they are exactly where the smell is strongest when you put your nose to it
What to check, and why in this order
- Empty and dry the fill tank first — On this form it is the reservoir the wash cycle never reaches
- Put your nose to the gasket, then to the open filter, then to the hose end. — Whichever is strongest tells you where to start and saves cleaning all three blind
Step by step
- Unplug the machine, lift out the filter assembly and the sump screen, and wash both in hot soapy water with an old toothbrush. — Time: several minutes.
Tools: toothbrush, washing-up liquid
- Empty the fill tank completely, wash it out, dry it, and leave it empty between uses. — Time: several minutes.
Tools: cloth
- Wipe the sump recess out with a cloth and remove anything sitting in it. — Time: several minutes.
Tools: cloth, torch
Before you start: safety
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never mix a dishwasher cleaner, vinegar or any acid with bleach or with a chlorine product — the combination releases a toxic gas. Use one product per cycle, run the machine empty when cleaning it, and unplug it before removing a filter.
When to stop and call a technician
Call for service when the smell returns within days of a full clean, when water is standing in the base between cycles, or when the smell is coming from behind the tub rather than from the filter, gasket or hose. A persistent smell with clean components usually means water is being retained somewhere you cannot reach. On a repeat of a fault that was already fixed once, say so when you call and describe what was done the first time — a technician treats a recurrence differently from a first failure, and it usually shortens the visit.

What this page does not cover
This is generalized information: it covers Dreame dishwashers as a class, not one family or model. It does not carry your model's error-code table, wiring, part numbers, capacities or ambient range — those are on the rating plate and in the documentation, which are the authority wherever they disagree with this page. It leads with one form, the tank-fill countertop machine that carries its own water rather than staying coupled to the tap, and flags where the others diverge. A second address covers this same brand, appliance and symptom from a different starting point, linked below. Any family- or model-specific page is reached from the brand hub below, and takes precedence over this one. Pages this one hands down to: DREAME Dishwasher: Odor or Mold (dreame-dishwasher-smell-mold); Common DREAME Dishwasher Problems (dreame-dishwasher-problems).
