--- title: "Dishwasher will not start" description: "Bertazzoni dishwasher will not start: the panel lights, you press start, and nothing happens — or nothing lights at all." url: "https://bertazzonimiami.support/symptoms/dishwasher-not-starting/" date_modified: "2026-08-27" Appliance type: "Dishwashers" --- # Bertazzoni dishwasher will not start ### The fastest diagnosis is the code Push the door firmly closed and try again — a dishwasher will not run if the latch switch has not made, and the machine is telling the truth when it says the door is open. Then cut power at the breaker for a full minute, not just the panel button. Between them these two find a good share of these before anyone drives out. ### The latch is a switch Every dishwasher refuses to run with the door open, and it decides that from a switch rather than from the door. A latch that has worn leaves the switch unmade with the door apparently shut — so the appliance is behaving correctly on bad information, and the fix is a small part rather than a board. It is the single most common cause of a dishwasher that will not start on any make. ### Where the code helps These dishwashers report, and a machine that will not start with a code showing has already narrowed the problem for you. Record it before you clear it. It is the only appliance on this site that gives you that advantage, and it is worth taking. The door latch and its switch The commonest answer by a distance, and inexpensive. The latch is a safety switch as well as a catch, and a worn one stops the machine as effectively as a failed board. A control lock or delayed start Set by accident, cleared in seconds. Worth ruling out before anything else because it costs nothing. No water arriving A supply valve turned off under the sink, or an inlet valve that has failed. The machine begins and abandons the cycle, which reads as not starting. A completely dead panel Points at the supply, the door switch or the main control — in that order, and the first two are cheap. The control board Last. A machine that will not start with a proven latch, a live supply and no lock set is the case that ends here. Close the door properly Firmly. Then try again. It sounds too simple and it is the answer often. A minute at the breaker A real power cycle, not the button on the panel. Is the water on The supply valve under the sink gets turned off during other work and not turned back. Any code at all On this machine there may well be one, and it names the condition. The latch, before the board What it usually means Lights on, nothing happens on start Completely dead panel Starts only if the door is pushed hard The fastest diagnosis is the code Push the door firmly closed and try again — a dishwasher will not run if the latch switch has not made, and the machine is telling the truth when it says the door is open.

The machine believes the switch, not the door. It is an inexpensive stocked part and it is the first thing checked, well before anything electronic — which is why it is worth pushing the door firmly and trying once more before you book. ### It hums for a moment and stops. That usually means the machine is starting and then deciding it cannot continue — no water, or water it cannot detect. Check the supply valve under the sink first; it is free and it is turned off more often than anybody expects during unrelated plumbing work. ### Can I reset it myself? Yes, and it is worth trying: power off at the breaker for a full minute. Write down any code first, because clearing it destroys the evidence. A code that stays away afterwards is a very different situation from one that returns immediately. --- **[Read full article: Dishwasher will not start](https://bertazzonimiami.support/symptoms/dishwasher-not-starting/)**
