Symptom
Bosch dishwasher smells
A smell when the door opens, or one that arrives on the dishes. Rarely a repair, usually a filter, and occasionally a drain hose installed in a way that lets the sink back into the machine.

Five ordinary causes
What this usually turns out to be
Cheapest and commonest first, which is also the order we check them in. They sit hundreds of dollars apart, and only the unit settles which one is yours.
-
The filter
What is caught in it is what you can smell. Out by hand, under a tap with a brush, and the problem usually leaves with it.
Maintenance & descaling from $145 -
The seal and the door edge
Residue collects along the bottom lip and in the seal channel where no water reaches. Wipe it with a cloth and see what comes off.
Maintenance & descaling from $145 -
The drain hose without a high loop
If the hose does not rise above the machine before it goes to the drain, sink water flows back in. That smell arrives from the sink, and it is an installation problem.
Installation & re-fitting from $185 -
Standing water
A machine that does not fully drain leaves an inch behind, and it goes stale within a day or two. That is the drain page rather than this one.

Not enough hot cycles
A machine used only on eco and short cycles never gets hot enough to clear grease from its own plumbing.

01
Take the filter out and smell it
The whole diagnosis, most of the time. Wash it with a brush and mild soap.
-
02
Wipe the door seal and the lower lip
Where water never reaches. What comes off on the cloth is usually surprising.
-
03
Look under the sink at the hose
It should rise up near the underside of the counter before dropping to the drain. If it runs flat or downhill, that is the smell.
-
04
Run an empty hot cycle
With a dishwasher cleaner or a cup of white vinegar. If the smell goes and stays gone, it was maintenance.

About Bosch dishwasher smells
The fastest diagnosis is the code
There is no code for this one and there does not need to be. Take the filter out and smell it — that answers the question in about ten seconds and it is the answer four times out of five.
The ten-second version
Take the filter out and smell it. If that is the smell, wash it and you are finished. It is the answer to most of these calls and it costs nothing to establish.
The one that is not maintenance
The drain hose is supposed to rise close to the underside of the counter before it drops to the waste. That high loop is what stops sink water flowing back into the machine. When a dishwasher is installed in a hurry the loop is often missing, and the result is a machine that smells of the sink and no amount of cleaning will change it.

Before you book
Questions about bosch dishwasher smells
It smells worse when we have been away.
Normal. Water sitting in the trap and the sump goes stale, and the machine has not run to flush it. Run an empty hot cycle when you get back.
Can I use bleach?
Not in these machines — the tub and internals do not care for it. A dishwasher cleaner or white vinegar on a hot cycle does the job without the risk.
Is a smell ever a real repair?
Occasionally, when it is standing water from a drainage problem or a hose installed badly. Both show themselves quickly once you have checked the filter.
