Error codeE1
ApplianceDishwasher
Quick answer
E1 on a Bertazzoni dishwasher is a slow-fill warning. Check the shut-off valve first.
Model compatibility: Bertazzoni reuses codes across series and model years, so E1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E1 means the dishwasher flow meter did not register the set amount of water within 4 minutes of the inlet step.
What E1 is timing
The first thing a dishwasher cycle does is bring in water, and the fill is timed. Three Bertazzoni models carry this code in their manuals (DW24XV, DW24PR, DW18PR). E1, which some lists print as E01, appears when 4 minutes of inlet pass and the flow meter has still not counted the defined water amount.
Possible causes for owners
One line of the owner-level table covers three possibilities:
a shut faucet
a restricted intake of water
pressure that is too low
The DW24PR display also has a water failure light among its status indicators, and it stands for a closed faucet.
First step
Check the supply line’s shut-off valve and turn it fully open, then run the cycle once more.
If E1 persists
For service, the manual prints seven things to check. They run from the water supply through the inlet valve and the inlet to the flow meter, then the pressure switch, the drain and finally the PCB.

Questions about E1
Is E1 the same as E01? Yes, some listings simply print it with a leading zero.
Which models carry it? The use and care manuals for the DW24XV, DW24PR and DW18PR.
Can an owner go past the valve? The owner-level table stops at the three causes, and the seven-item list is a matter for service.
