Gaggenau's own manual is direct about this one: the power voltage is too low, and there is no problem with the appliance. Its instruction is to have an electrician check the supply voltage and the electrical installation feeding the appliance, which puts this squarely on the circuit the appliance was connected to at hookup. Gaggenau appliance display What to do when E:9001 shows on the appliance ### Kind of code Power and wiring Some new appliances check the supply they are plugged into and say so when it is wrong: voltage too low or too high, the live and neutral reversed, or no ground. On a new install that points to the outlet, the circuit behind it or the cord kit, not to the appliance. Leave it unplugged or the breaker off; a changed outlet, a new circuit or a panel repair is a licensed electrician's job, and the appliance is connected once that is done. ### Usually leads to Pre-installation site check A visit before you order: opening, path in, gas, water, drain, power and exhaust checked against the spec sheet. ### Shows up as Breaker Trips on the First Run: Leave It Off and Find Out Why When the breaker trips on the first run, power to a newly installed appliance is cut the moment it starts to heat, spin, cool or pump. ### Make Gaggenau Gaggenau installs are architectural: flush wall ovens, combi-steam ovens, integrated columns and cooktops set into stone, each to a tight cutout drawing. ### Source Gaggenau US dishwasher use and care manual, document 9001798908_A Confirmed in Gaggenau's US dishwasher use-and-care and installation manual (document 9001798908_A). ## Before you book, in this order. Each step comes from Gaggenau's own guidance for E:9001 on its appliances. Follow it to the end: the last card says whether this is a visit. 01 Confirm the appliance is on its own dedicated circuit rather than sharing one with other heavy loads. 02 Note whether lights elsewhere in the home dim when the appliance is running, which points at a shared or undersized circuit. 03 Do not attempt to open the electrical panel or test voltage yourself; this is licensed electrician work. 04 Book a visit and mention the exact wording of this alert, since Gaggenau's own manual calls for an electrician rather than a technician for the appliance itself. ### Still there? It usually turns into [pre-installation site check](https://applianceinstallation.center/services/diagnostic-visit/). Book with the code and the model number. ### What not to do This is not a failure inside the dishwasher's own electronics. Gaggenau's own manual states there is no problem with the appliance and directs the fix at the building's electrical supply. ## What you may notice with it.

Confirm the appliance is on its own dedicated circuit rather than sharing one with other heavy loads. If it comes back, it needs a visit. ### Why would a brand-new appliance flag a voltage alert instead of simply not turning on? Gaggenau's control electronics are able to detect incoming power that reads lower than expected and raise this specific alert, rather than behaving erratically or not starting at all. ### Is this something the installer should have caught before finishing the hookup? A properly rated, dedicated circuit is generally checked as part of a licensed installation, so this alert appearing afterward often points at a broader house-wiring issue rather than something the installer missed. ### Can I just try a different outlet or circuit myself? No — Gaggenau's own instruction is to have an electrician check the supply voltage and the installation. Moving the connection yourself isn't the documented fix and involves working with house wiring. --- **[Read on the site: Gaggenau E:9001: incoming power to a dish care machine](https://applianceinstallation.center/error-codes/gaggenau-e9001/)** **[Book a visit with ApplianceInstallation.center](https://applianceinstallation.center/schedule/)**
