What does MEIKO error code 11 mean?
On Meiko M-iClean U undercounter dishwashers, message 11 asks staff to carry out maintenance. It is a reminder on the color display, not a stop. The maker says it is possible to continue working, and to call a service technician. The machine keeps an error memory that is checked each year, so this reminder fits into a regular service schedule. Unlike the messages that report a failure during a cycle, message 11 is about time and upkeep. It prompts attention to wash arms, sieves and filters that need cleaning, to water treatment parts that are due for service, and to any settings or counters that triggered the reminder. If the daily and weekly cleaning has been done and the message comes back, the interval has probably passed and a technician needs to do the annual work. The display text is 11.
