What does MEIKO error code 14 mean?
On Meiko M-iClean U undercounter dishwashers, message 14 reminds staff that heat is being lost through an open door. The color display shows it as an operator notice. It is a gray information message, and nothing is broken when it appears. The maker's step is simply to close the door to prevent energy loss. Closing the door is all the machine asks, and the message clears once the heat stays in. An open door lets the heated air and steam out, so the machine works harder to keep the tank and boiler at temperature. The reasons in the manual are a door left open between loads, a door that does not shut fully, a door switch that reads open, and racks left half in the machine. If the message stays with the door visibly closed, the door switch or the latch is the next thing to look at. The display text is 14.
