Bosch Dishwasher Error Code E04
If your Bosch dishwasher shows Error Code E04, it usually indicates that the appliance has detected a problem with the water flow or the spray system during the wash cycle. When this happens, the dishwasher may stop the program or fail to clean dishes properly.
The dishwasher relies on correct water pressure and functioning spray arms to distribute water throughout the appliance. If the system detects a fault, it may display the E04 error code.

What the E04 Error Means
The E04 error code generally means the dishwasher has detected an issue with the spray arm system or water distribution inside the appliance. This can prevent water from circulating properly during the wash cycle.
If the dishwasher cannot distribute water as expected, it may pause the program and display the error code.
Common Reasons This Error Appears
Blocked spray arms
Food debris or limescale buildup can sometimes block the spray arm holes and affect water distribution.
Poor water pressure
Low water pressure entering the dishwasher may prevent the spray system from working correctly.
Temporary system fault
Occasionally the dishwasher may display an error after a temporary interruption in the wash cycle.
Safe Checks You Can Try
Before contacting a technician, there are a few safe checks you can perform.
Inspect the spray arms
Remove the dishwasher racks and check the spray arms for blockages. If any of the small holes appear clogged with debris, gently rinse the spray arms under warm water.
Check water pressure
Make sure the water supply valve connected to the dishwasher is fully open and that the appliance has normal water pressure.
Reset the dishwasher
- Turn the dishwasher off using the power button.
- Switch off power at the wall socket or circuit breaker.
- Wait 1–5 minutes.
- Restore power and start a new wash cycle.
A reset may clear temporary system errors.
