Ideal Pump Complete Kit 176858

The 176858 pump complete kit is a circulation pump assembly supplied by Ideal for its Vogue range of domestic gas boilers. The pump moves heated water from the boiler through the primary circuit and around the radiators, so it sits at the centre of the appliance's hydraulic operation. This kit is the complete pump assembly rather than an individual component, making it the part to fit when the existing pump body or head has failed.

• No heating or hot water despite the boiler firing and the thermostat calling for heat
• The boiler repeatedly locks out or shows a pump-related fault code
• Radiators warm unevenly, or the flow and return temperature difference is unusually wide
• Grinding, whining or rumbling noise from the pump housing
• The pump head is hot to touch but the body is not circulating water

• Check the GC number on the appliance data badge against the list above to confirm the boiler variant
• Confirm the existing pump carries the number 176858 or the alternative 1782705 before ordering
• Inspect the pump seals and gaskets on removal and replace them if they show signs of hardening or leakage
• Work on the boiler's water circuit should be carried out by a competent person; isolate the appliance and drain down before removing the pump
