Every dishwasher cycle begins by taking in water, and the machine times that step. On a Bertazzoni dishwasher, E1 (shown as E01 in some listings) means the step ran too long. The use and care manual says that if the flow meter cannot detect the defined amount of water after 4 minutes of the inlet step, the dishwasher warns with E1. Bertazzoni lists this code in the use and care manuals for the DW24XV, DW24PR and DW18PR dishwashers.
Three causes listed for owners
The manual with the owner-level table gives three possible causes in one line:
- the faucet is not open
- the water intake is restricted
- the water pressure is too low
The DW24PR manual’s list of status indicators on the display also includes one for water failure, meaning the faucet is not open, which fits the first cause.
Start here
- Find the shut-off valve on the supply line and make sure it is fully open.
- Start the cycle again.
What service goes through
For a code that persists, the manual prints a seven-item check list: water supply, inlet valve, inlet, flow meter, pressure switch, drain and PCB. It is worth reading because it shows how the machine is built:
| Item | Role |
|---|---|
| Water supply, inlet | Water has to arrive and enter |
| Inlet valve | The electric valve that opens to let water in |
| Flow meter | Counts the water actually entering |
| Pressure switch | Senses the water level in the tub |
| Drain | Listed among the items to check |
| PCB | The control board that reads the sensors |
