Button board with display for MAZZER Mini electronic and Mini filter professional coffee grinders. Round green printed circuit board with a four-digit red display, five buttons and two through holes, as shown on the part. The display is marked LFD4155-31-PF; two ULN2003A chips can be read on the board.
Data to compare with the part being replaced: manufacturer code S000SPU03/DQQ, the same number stamped on the back of the board together with 10360. ⚠️ Count the BUTTONS and check the position of the two holes and of the connector: similar round boards carry different displays and keys.
When to replace it: if the display can no longer be read or shows incomplete digits, if one or more buttons stop responding, or if the board is oxidised or burnt out.
Always check the code and model of the machine before purchasing.
