Description
Worcester 87186445620 3-Way Valve Cartridge – Greenstar 2000
Replace a worn or sticking diverter cartridge with this new compatible Worcester 87186445620 3-way valve cartridge. It fits Worcester Greenstar 2000 25kW and 30kW combi boilers.
The cartridge sits inside the three-way valve assembly and helps direct water between the central heating and domestic hot-water circuits. Therefore, a worn or seized cartridge may cause poor hot water, heating problems or incorrect switching between operating modes.
However, similar symptoms can result from the actuator motor or another hydraulic component. Consequently, a qualified engineer should diagnose the boiler before ordering a replacement.
This new compatible component is designed as a direct replacement where Worcester part number 87186445620 is required. In addition, it comes with a 12-month warranty for added confidence.
