The fill stage and low pressure
If E07 shows up within the first few minutes, you can usually hear that the tub is taking its time. On a good supply, a dishwasher fills in a couple of minutes and goes quiet. When pressure is poor, the valve stays open longer than the machine expects, and the control may take a dim view of that. The inlet valve is the electrically operated gate that lets water in, and the control expects the tub level to rise within a set window while it is open.
Homes high on San Francisco hills, upper-floor flats served by long risers, and kitchens that were recently re-piped can all have lower pressure at the dishwasher than elsewhere in the house. None of that makes E07 certain, but it helps explain why two kitchens with the same model behave differently.
Take the code with some caution
For this Bertazzoni dishwasher, E07 has no confirmed universal meaning, and the code is not proof of a faulty valve. It tells you what the control reported, and the technician finds the reason by testing.
Supply checks to try first
- Open the cabinet under the sink and make sure the dishwasher shut-off valve is turned fully, not partway.
- Run the kitchen faucet and see whether the flow is strong. A weak trickle there means the dishwasher is also starved. A strong flow there points the search toward the dishwasher’s own inlet side instead.
- Look at the braided supply line for a sharp bend that could restrict flow.
- Check whether anyone had water shut off nearby, since sediment can follow a repair on the main.
Do not remove the supply fitting to look inside it. Water behind the valve is under pressure and the fitting is not designed for casual handling.
Sediment after plumbing work
After a main shut-off or street repair, small grit can lodge in the screen at the inlet. Washing machines and dishwashers suffer first because their valves are narrow. If E07 started the week of a plumbing job, say so. That detail helps separate a blocked inlet screen from a fault in the level sensing.
When it needs a technician
If the faucet flow is healthy and the valve is fully open but E07 comes back at the same moment in the fill, the inlet side of the machine needs measuring. That involves the valve, the level sensing, and the wiring between them, all of which are tested with the machine open. The visit starts with diagnosis, and you approve any repair in writing first.
Frequently asked questions
The machine expects the tub to fill in a set time. Poor pressure stretches that time and can trigger a protective response.
That means loosening a pressurized fitting, which is best left to the technician.
Not always. Timing varies by model, so note when you see it.
Then the cause is likely inside the machine, and a visit is the next step.
Model compatibility: Bertazzoni reuses codes across series and model years, so E07 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
