Bertazzoni Legacy 24-Inch Dishwasher Code E1: Water inlet too slow

What E1 means

On Bertazzoni legacy dishwashers in the DW24XV, DW24XT, DW24PR and DW18PR families, E1 is a water inlet warning. On the DW24XV and DW24XT it means the fill time ran longer than expected because the faucet is not open, the water intake is restricted or the water pressure is too low. On the DW24PR and DW18PR the flow meter did not detect the set amount of water within 4 minutes. The cycle stops with E1 on the display.

Common causes of E1

Water supply valve under the sink is closed or only partly open
Inlet hose kinked or the inlet screen blocked with debris
Household water pressure too low at the time of the cycle
Inlet valve or flow meter not passing water as expected
Control board not reading the fill signal

✓ One safe check you can try

1. Press Cancel and wait for the drain to finish. 2. Open the shutoff valve under the sink all the way. 3. Check that the fill hose behind the dishwasher is not bent or crushed. 4. Run the kitchen faucet for a moment to confirm normal pressure. 5. Start a short cycle again. If E1 returns, leave the dishwasher off and call us.

! Why to stop there

A hose that is only partly blocked looks the same as a bad inlet valve, so guessing at parts wastes money.
Pulling the dishwasher out to reach the inlet valve means working beside a water line and a live wire connection.
Running the cycle again and again with a weak fill can leave the wash unfinished and the dishes dirty.
We test flow, valve and board in order, and quote in writing before work begins.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E1E1 questions

What does E1 mean on my Bertazzoni dishwasher?

It means the machine did not take in water as quickly as it should. Either the supply is closed or restricted, the pressure is low, or the part that meters the water is not reporting a proper fill.

Which models does this E1 description cover?

It covers the 24-inch and 18-inch legacy machines sold in the US, such as the DW24XV, DW24XT, DW24PR and DW18PR. Newer Heritage dishwashers report a water inlet problem with FF instead.

Can I keep using the dishwasher with E1?

Not until the fill problem is cleared. Check the faucet valve and hose first. If the code comes back on the next start, we can trace the inlet path for you and give a written price first.
