Full details
The Worcester Bosch Pressure Gauge (87161164280) is an essential component designed for homeowners and heating technicians who need to monitor the hydraulic pressure of their boiler system. Its primary benefit is providing a clear, reliable visual indicator to help detect system leaks or expansion vessel issues before they cause total boiler failure. While it is a precision-engineered genuine spare part, please note that it must be installed by a certified Gas Safe engineer to ensure safety and system integrity.

FAQs
Can I replace the pressure gauge myself?
No. Due to safety regulations, all boiler spare parts must be fitted by a certified Gas Safe engineer.
What is the correct pressure range for my Greenstar boiler?
Generally, the system should operate between 1.0 and 1.5 bar when cold. Check your specific user manual as some models vary.
How do I know if the gauge is faulty?
If the needle remains stuck despite system pressure changes, or if the dial is clouded/leaking, it likely requires replacement.
Is this a universal pressure gauge?
No, this is a model-specific part (87161164280) designed for Worcester Bosch systems.
Does a low pressure reading always mean a leak?
Not necessarily. It could indicate a faulty expansion vessel or pressure relief valve, which should be diagnosed by a professional.
Troubleshooting
Gauge reading does not change when filling the system
The capillary tube or gauge connection may be blocked by debris. Consult a Gas Safe engineer to check for obstructions.
Gauge needle is fluctuating wildly
This often indicates a faulty expansion vessel. Verify the expansion vessel's air charge.

Setup, Compatibility & Care
This component is compatible with various models including ErP I System and Greenstar units. Because this is a pressurized water system component, it is mandatory that all boiler spare parts are fitted by a registered Gas Safe engineer. Attempting to install or adjust this gauge without professional certification can void your boiler's warranty and create hazardous gas or water leaks. For care, ensure the boiler cabinet is kept clean and dry, and avoid applying impact or force to the gauge face to maintain its calibration accuracy.
