Bertazzoni Dishwasher E4 Error Code

Overflow alarm

Water that reaches the base is picked up by a switch, and the dishwasher then shows E4 (E04 in some lists). Bertazzoni’s definition: overflow, some element of the dishwasher leaks.

Safety lines first

1. Before calling for service, turn off the main water supply.
2. If the base pan holds water from an overfill or a small leak, remove it before restarting.

Starting another cycle with a wet pan is not advised.

Checks printed in the manual

• use of the detergent
• whether the dishwasher is level
• the micro-switch
• the drain pump
• the amount of water filled
• where the leakage is

Detergent use and levelness are the two a homeowner can reasonably look at. The others require access to parts.

Q&A

Is drying the base enough to run it again? The manual permits a restart only after the water is removed, and it still lists finding the leak.

Related codes

• F1: overflow as reported by F-code models
• F3: continuous water entry
• E1: a fill that is too slow

Before restarting

The wording is clear on one point: the water has to be out of the base pan before the dishwasher runs again, and the main supply stays off until service has been called. After that, the six checks in the manual start with the detergent used and the level of the machine, which are the two items an owner can reach.
