HI is a high voltage failure code. No owner fix is listed; the next step is service.
Model compatibility: Bertazzoni reuses codes across series and model years, so HI 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
HI is a high voltage failure; the manual says to contact service.
If a Bertazzoni dishwasher displays HI, the manufacturer’s fault table translates it as a high voltage failure. One instruction sits beside it, contact service, and the table lists neither a reset nor a part to clean nor possible causes.
Sensible caution
Because voltage relates to the supply reaching the machine, repeated restarts are not a test worth running.
Stop whatever cycle is running and jot down what the display shows.
Take the plug out of the socket, or turn the breaker off for a hard-wired unit, before anyone checks behind the kick panel.
Do not handle the plug or the junction box. Electrical wiring in the home is for an electrician or technician.
Whether the trouble is in the house wiring, the power cord or the dishwasher’s own control is not stated by Bertazzoni.
Facts to have for the call
Technicians appreciate plain observations. Did HI appear at the moment of switch-on, or mid-wash? Are other lights or appliances on that circuit acting strangely? Has the dishwasher been shifted or put back in recently? Nothing here is a diagnosis, and the manual does not ask for any measurement.
What the table does not offer
There is no published fix for the owner, so unplugging and calling is the whole plan.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
