Gaggenau coffee machine display What to do when Contact customer service shows on the coffee machine ### Kind of code Control board and power The electronics that read the keys and run the grinder, the pump and the heater have flagged a problem with themselves or with the power reaching them: a supply that dipped or spiked, a board that lost its settings after an outage, a display or touch panel that stopped answering, or a relay that stuck. One switch-off at the key or the breaker clears a passing glitch; a message that returns, or any hot smell, means the power stays off and a technician tests the board. ### Usually leads to Coffee machine control board repair Testing and replacing the power board, control board and touch panel of a coffee machine, and the sensors they read. ### Shows up as What a Coffee Machine Error Code or Warning Symbol Means A coffee machine error code may show as a short string of letters and numbers, a flashing symbol for water, grounds or the brew unit, a short sentence on a text display, or a machine that stops with one light blinking. ### Make Gaggenau Gaggenau coffee systems are serviced in place after the owner describes what the last cup looked like. ### Source Gaggenau CMP 250 Fully Automatic Espresso Machine Use and Care Manual, Simple troubleshooting Printed in the US Use and Care Manual for the 200 series CMP 250 built-in espresso machine. ## Before you book, in this order.

Switch the machine off with the main switch and leave it off. If it comes back, it needs a visit. ### Is it safe to keep using my Gaggenau after Contact customer service appears? The machine normally will not brew in this state, and repeated restarts can hide what the technician needs to see. Leave it off until the visit. ### Does a Gaggenau service visit mean taking the machine out of the wall? Only for some repairs. The technician decides after testing, and handles the removal from the niche if it is needed. ### What is the difference between this Gaggenau screen and a numbered error? The numbered error gives the owner a screen step to try first. This one skips straight to service. --- **[Read on the site: Gaggenau CMP 250: Contact customer service](https://coffeemachinerepair.center/error-codes/gaggenau-contact-customer-service/)** **[Book a visit with CoffeeMachineRepair.center](https://coffeemachinerepair.center/schedule/)**
