The short answer
A GE dishwasher smells because something organic is staying wet somewhere it should not. Nearly always that is the filter and sump, the seal and door edge, or water sitting in a drain hose that never fully clears. Find where the water is staying rather than masking the smell, because a cleaning cycle removes the odour for a week and changes nothing.
Causes, ranked for this Ge dishwasher
- Filter and sump holding food soil — Why: The filter collects everything the wash removes and stays warm and damp between programmes, which is the ideal place for the smell to develop and the first place to look.
- Door edge, seal and the lip below the door never washed — Why: The spray arms cannot reach the door edge or the underside lip, so soil accumulates there indefinitely and holds odour after the tub itself is clean.
- Water retained in the drain hose without a high loop — Why: A hose that sags or lacks a rise above the tub keeps stagnant water permanently and lets sink odours travel back, which is why the smell is of drains rather than food.
- The machine used rarely or on low-temperature programmes only — Why: Short cool programmes never reach a temperature that clears biofilm, so a lightly used machine develops a smell that a heavier user never sees.
- Sink waste, disposer or trap rather than the dishwasher — Why: The smell is often in the plumbing the machine drains into, which is why cleaning the dishwasher repeatedly never fixes it.
What to check, in order
- remove and wash the filter assembly and clear the sump beneath it. — Because: it is the top-ranked source and it is where the soil actually is.
- wipe the door edge, the seal and the lip below the door. — Because: the wash water never reaches these and they hold odour after everything else is clean.
- note whether water stands above the filter after a programme. — Because: a drainage fault causes the smell, and no cleaning will fix it while it persists.
- check the drain hose for a high loop and the sink waste for its own smell. — Because: a drain odour comes from the plumbing rather than from the machine.
Checks you can safely do yourself
- Switch the machine off at the breaker, remove the filter assembly and wash it under running water with a brush and gloves on. — Tools: gloves and a brush — Time: several minutes
- Clear the sump beneath the filter carefully, looking for glass fragments, and wipe it out. — Tools: gloves and a torch — Time: several minutes
- Wipe the door edge, the seal, and the lip below the door where soil collects out of reach of the spray arms. — Tools: a cloth and warm soapy water — Time: several minutes
- Check the spray arm holes for blockage and clear them with a cocktail stick. — Tools: a cocktail stick — Time: several minutes
- Confirm the drain hose rises above the tub before dropping to its connection, then run the hottest programme empty. Stop here: the pump is reached from underneath. — Tools: a torch and a cable tie — Time: the better part of an hour, mostly waiting
Before you open anything
Safety
unplug-before-service
Wear gloves when clearing a dishwasher sump, since broken glass is the commonest thing found there and it is not always visible. Kill power at the breaker before reaching in. Never mix cleaning products in the tub, and in particular never combine bleach with anything acidic.
Where the owner fix ends
Cleaning the filter, sump, seal and spray arms, and forming a high loop, are owner work. Call a technician when water still stands after a programme with a clean filter and clear hose, because the pump is what remains; and call a plumber when the sink waste or trap smells independently of the dishwasher.
