A Bosch dishwasher showing E3300 is reporting a condition associated with water cannot enter the dishwasher normally. Use the code as a starting point, then pair it with the full model/E-Nr and the way the appliance behaves.
The guidance below stays at the owner-safe level: observe the symptom, check only accessible items supported by the model documentation, and stop before opening protected electrical, water, gas, or mechanical systems.
At a glance
- Code: E3300
- Appliance: Bosch Dishwasher

- Diagnostic direction: the incoming-water or fill path
- Service area context: San Francisco; confirm coverage by ZIP code
How to read this warning
The technical anchor for E3300 is water cannot enter the dishwasher normally. That description should remain unchanged when the page is imported. What can vary is the hardware behind the condition, so the model/E-Nr and the observed behavior are necessary context.
For this reason, E3300 should be used to narrow the troubleshooting path toward the incoming-water or fill path, not as automatic proof that one specific component has failed.
Symptoms that add diagnostic context
Before changing settings or cycling power, note what the appliance is doing. Useful observations include:
- The dishwasher can fail to take in water.
- The selected program can stop near the beginning.
- You can hear repeated attempts to take in water.
- The displayed warning can come back on the next cycle.
Where diagnosis may need to look
Based on the source record, diagnosis may need to consider the following possibilities without assuming any one of them is confirmed:
- An incoming water supply that is restricted or unavailable.
- An inlet hose that is kinked, crushed, or damaged.
- Flow-meter, inlet-valve, sensing, wiring, or control fault.
Safe checks before service
- Confirm the household water supply to the dishwasher is open.
- Look over the visible inlet hose for a kink, crushing, or obvious damage.
- Write down whether any recent plumbing or installation work occurred.
- Avoid open the inlet valve or internal flow-meter circuit as a homeowner check.
These steps are meant to gather useful information without exposing live wiring, bypassing an interlock, defeating a leak-protection device, or opening a system the owner documentation does not designate for user access.
Safety stop conditions
Turn off the water and stop use if there is active leaking.
What service needs to determine
If water supply and the visible inlet path are normal but the code returns, the fill valve, flow measurement, sensing, wiring, or control path requires model-specific diagnosis. When requesting service, include the complete Bosch model/E-Nr. Similar-looking dishwashers can use different controls, pumps, drying systems, and diagnostic logic.
A useful service request includes the exact display, what the appliance was doing immediately before the warning, and which external checks were already completed.
Before parts or service are selected
Use the complete Bosch model/E-Nr when matching E3300 to technical documentation. Similar-looking products can use different sensors, controls, pumps, motors, or diagnostic logic.
FAQ
For the source record used here, E3300 is associated with water cannot enter the dishwasher normally. The complete model/E-Nr still matters because Bosch can use different hardware and diagnostic logic across product families.
Do not continue if the warning is accompanied by the stop conditions listed above. Water near electrical parts, leaking, smoke, a burning odor, sparking, or repeated breaker trips are reasons to leave the appliance off and arrange service.
Where the Bosch documentation for the exact model allows a normal power reset, use it once after recording the code. A returning warning means the underlying condition still needs attention; repeated resets are not a repair.
Not necessarily. An error code narrows the detected condition or system. The model number, symptoms, and model-specific testing are still needed before selecting a component.
Have the full Bosch model/E-Nr, the exact E3300 display, the cycle stage or operating state when it appears, the visible symptoms, and the safe checks already completed.
