Worcester Bosch Pump Assembly 15-60 230V 8716119824

This is a Worcester Bosch circulating pump assembly rated 15-60 and running on a 230V supply. It moves primary water around the boiler and the heating circuit, so it sits at the centre of the appliance's circulation rather than at the periphery. The assembly is used across the Worcester Bosch Greenstar and British Gas badged combi and system ranges.

• No circulation: radiators stay cold while the boiler fires, or the flow and return pipes at the boiler show little temperature difference.
• The pump is noisy in use, with rumbling, grinding or a whine that changes with speed setting.
• The boiler locks out or shuts down shortly after ignition because the flow switch or temperature sensors do not see movement.
• The pump head is hot but not turning, or the shaft cannot be turned by hand with the power isolated.
• Repeated overheat faults on the appliance where the pump is the only circulation source.

• Check the GC number on the appliance data badge against the compatibility list; the same boiler family can use more than one pump variant.
• Confirm the number on the old pump matches 8716119824 or one of the previous numbers listed above before ordering.
• Check whether the pump gasket or sealing washer is reusable; a replacement seal is normally needed when the head is removed.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
