# Bertazzoni dishwasher error code HI

### What HI means on a dishwasher

High voltage failure. This one is about the electricity arriving at the machine rather than about the dishwasher. That comes out of the dishwashers manual this maker publishes for the machine, and it is one of only three documents in the whole current catalog that carries a code table at all.

### What to do

- Do not keep restarting it. A supply problem will not improve by being asked again.
- Mention any other appliance on the same circuit behaving oddly — this is occasionally an electrician's job rather than an appliance repair.

Write the code down before you clear it, and photograph the display if you can. On a machine that only shows a problem intermittently, that is the one piece of evidence that disappears the moment power is cycled, and it is the first thing anybody will ask you for.

### What the repair is

Conditions like this one end at [Dishwasher control & electronics repair](https://bertazzonimiami.support/services/dishwasher-control-and-electronics-repair/) more often than anywhere else. The figure on that page is a starting point; the exact cost is confirmed after an on-site diagnostic and agreed in writing before anything is opened.
