- “Machine dead with a leak code showing”
- “Water at the front edge of the door”
- “A damp cabinet base with no visible puddle”
Symptom
Bosch dishwasher leaking
Water on the floor, or a machine that has stopped and refuses to start. The leak protection on these dishwashers catches water in the base before it reaches your kitchen — which is why the first sign is usually a machine that will not run rather than a puddle.

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 door seal
Hardens with age and stops sealing at the bottom corners first. The cheapest cause here, and the one that leaves water at the front edge of the door.

The sump and its gasket
Under the filter. Weeps rather than pours, which is why it fills the base pan over weeks and trips the sensor before anybody sees water.

Hose connections
Particularly after a machine has been pulled out and pushed back for any reason. Worth suspecting if the leak started right after other work.

The inlet valve
Weeps under pressure even when the machine is off, so the base fills between cycles. A machine that trips overnight without running points here.

Too much detergent
Foam escaping past the door seal looks exactly like a leak. Worth ruling out first if it started when the detergent changed.
In five minutes
Before you call anybody
None of it needs tools, and all of it makes the visit shorter.
-
01
Turn the water off
At the valve under the sink, before anything else. This is the one check that has to happen first.
-
02
Look at the door seal
Run a finger round it, especially the bottom corners. Hard, cracked or flattened is your answer, and it is a modest repair.
-
03
Check the detergent
If it started when you changed brand or dose, run one cycle with half the amount before booking anything.
-
04
Photograph the code, then book
And do not tip the machine to clear it. That empties the pan and resets the lockout without repairing anything.
How it shows up
What people describe when they call
Two shortcuts
Narrow it down before anybody arrives
A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.

If there is no code at all
The data plate is inside the cabinet, upper left wall or behind the grille. All models

About Bosch dishwasher leaking
The fastest diagnosis is the code
If the machine has stopped with a leak code, that is the protection system rather than the problem. Turn off the water at the valve under the sink and leave it off — the machine has already decided it is cheaper to stop than to keep going.
The lockout is a feature
A float and a sensor sit in the base pan of these machines. When water reaches them the dishwasher shuts down, drains what it can and refuses to restart. It is the reason a small leak here becomes a machine that will not run rather than a ceiling repair downstairs — and it is why the code is not the problem, it is the alarm.
What is actually leaking
- The door seal, hardened and no longer touching at the corners
- The sump or its gasket, weeping slowly under the filter
- Hose connections, especially after the machine has been moved
- The inlet valve, which lets water past even when the machine is idle
- Foam from too much detergent, which is not a leak at all

Questions about bosch dishwasher leaking
There is no water on the floor. Why has it stopped?
Because it caught the water first. There is a sensor in the base pan, and it shuts the machine down before a slow leak reaches your floor — which in an apartment above somebody else's ceiling is worth a great deal.
Someone said to tip it backwards to reset it.
It works and we would rather you did not. Tipping drains the pan and clears the lockout; the leak is untouched. The next time the pan fills you may be away for the weekend.
How urgent is it?
With the water off at the valve, not urgent at all. With the water on and a machine that keeps running, urgent — especially above the ground floor.
