Bertazzoni PE304INDXV Cooktop Code E1: Supply Voltage Below 85V

What E1 means

On Bertazzoni professional induction cooktops such as the PE244INDXV, PE304INDXV and PE365INDXV, E1 means the supply voltage is too low, less than 85V. The cooktop will not run properly in that condition. The instruction is to check the power supply, and if it is normal, to turn the cooktop back on. Owners see E1 and a cooktop that stops or refuses to start.

Common causes of E1

A power supply feeding the cooktop with too little voltage
A loose or poor connection at the supply
A momentary dip that clears when the cooktop is switched on again

✓ One safe check you can try

1. Switch the cooktop off and check whether other appliances on the same supply are acting up. 2. Look at the breaker to make sure it is fully on. 3. Turn the cooktop back on once the supply seems normal. 4. If E1 returns, stop and call us so the supply can be checked.

! Why to stop there

Low voltage can come from the house wiring, which is beyond a cooktop repair.
Measuring a 240V supply and its connections is work for a licensed professional.
We give a written price first, and our repairs carry a 30-day workmanship warranty.

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

How low does the voltage have to be for E1?

The code appears when the supply drops below 85V. That is far under what a cooktop on a 240V circuit should see, so something is wrong with the feed.

Will E1 go away on its own?

If it was a brief dip, switching the cooktop back on may clear it. A repeating E1 means the supply keeps falling low and should be examined.

Is E1 the opposite of E2?

On this series, yes. E1 means the voltage is too low, while E2 means it is too high, above 285V. Both send you to check the power supply first.
