Worcester Bosch Digital Programmer 87161053910

The Worcester Bosch 87161053910 is a digital programmer — also referred to as a clock, timeclock or timer — used to set when central heating and hot water are fired up. It gives the user control over daily and weekly operating periods so the appliance runs when the home needs heat rather than continuously. It is supplied as a direct replacement part for Worcester Bosch Danesmoor and Greenstar Camray appliance families.

• The display is blank, dim or showing scrambled characters.
• The appliance fires outside the set heating or hot water periods.
• The programmer loses the time and date after a power interruption.
• Buttons do not respond, or settings cannot be changed or saved.
• Heating or hot water fails to come on when a timed period is due.

• Confirm your appliance model against the compatibility list, as the programmer is shared across several Danesmoor and Greenstar Camray variants.
• Check the existing programmer's part number and any alternative number printed on the unit before ordering.
• Note the alternative part number 1014519, which may appear on older documentation or labels.
• Isolate the appliance from the electrical supply before removing or refitting the programmer.
