In one paragraph
A dishwasher smells when food residue is being held somewhere warm and damp — the filter, the sump, the drain hose or the door gasket — and none of those are repairs. On a Crosley water that will not clear from the sump comes first, because on a machine that has been in the same place for years, the parts that have been moving all that time are where the fault usually is. Filter cleaning, hot maintenance cycles and drain checks are owner work; only a smell that survives all of them needs a visit. The order below is written for a long-service machine in a settled installation; on a unit that was installed or moved in the last few weeks, setup and supply faults rank above everything here.
What it looks like from the front
- The smell is worse after the machine has stood unused — Standing water going stale in the sump or a dry trap letting drain odour in.
- A black film in the gasket or under the filter — Visible biofilm, which is the source rather than a symptom.
- A sour or drain-like smell when the door opens — The filter and sump are the first suspects.
- NEAR MISS — A burning or hot plastic smell — That is electrical and belongs on the safety page; stop using the machine.
The causes and their order
- Water that will not clear from the sump — First on this brand: on a machine that has been in the same place for years, the parts that have been moving all that time are where the fault usually is. A partial drain fault leaves more water standing than the design intends, which turns a maintenance issue into a permanent one.
- Residue in the door gasket and around the tub lip — Second: The gasket channel and the tub lip stay damp and are rarely cleaned, so they hold a film that smells strongly when the door is opened.
- A filter and sump holding food residue — Third: The filter collects everything that comes off the dishes and keeps it in standing water between cycles, where it goes sour within a day or two.
- Only ever running short, cool programmes — Fourth, and the last to suspect: Eco and quick cycles never get hot enough to clear grease from the sump and hoses, so residue accumulates in a machine that appears to be working perfectly. These units change homes more than most, and levelling, hose routing and venting are what the move breaks first.
The order to work in
- Check the water level over the filter at the end of a cycle — Water above the filter after every cycle is a drainage fault and it belongs on the drainage page. First, because a long-service unit reports its consumables before it reports anything else, and this check costs nothing.
- Wipe the gasket with a white cloth and look at it — A grey or black mark on the cloth is the residue that is causing the smell.
- Lift the filter and smell it — If the smell is on the filter, the diagnosis is complete and the fix is a brush and hot water.
Owner-side steps
- Clean the gasket, the tub lip and the door edge with hot soapy water — Dry afterwards and leave the door ajar so those surfaces are not permanently wet.
Tools: clothAbout 20 min
- Wash the filter and coarse screen in hot soapy water and clear the sump — Wipe the sump walls too; a film there re-seeds the smell within days.
Tools: brush, spongeAbout 25 min
- Stop here if the next move needs a meter on live terminals — That is where an owner check ends and a service call begins.
Working safely on this machine
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Close the taps before any hose comes off, and never bypass a door or lid switch to run the machine open.
When this becomes a service call
Call only when the filter, sump, gasket and hose have all been cleaned, hot maintenance cycles have been run and the smell persists — that usually means water is standing somewhere it should not.

Scope of this page
This is the family-agnostic page for Crosley dishwashers. Nothing more specific exists to send you to at the moment; a model-level page, once written, is linked here and is the better answer. Deliberately not here: wiring colours, resistance values, torque figures and part numbers, which differ between families.
