What it is
The Worcester Bosch 871860020A0 is a suction pipe used in the manufacturer's Greenstar Compact and Si Compact boiler ranges. It forms part of the internal pipework that carries air or condensate away from the combustion and heat exchanger assembly, so the boiler can run at its designed operating conditions. The pipe is supplied as a Worcester Bosch spare and is listed under the Pipes & Hoses spare part category.
Signs this part needs replacing
- Boiler locks out or fails to establish a stable flame during ignition
- Whistling, gurgling or unusual suction noise from the boiler casing
- Visible cracking, splitting or perishing along the pipe wall
- Water or condensate tracking around the pipe connections
- Debris or scale build-up restricting flow through the pipe bore
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the correct variant.
- Confirm the part number 871860020A0 matches the pipe currently fitted before ordering.
- Inspect the pipe connections and any seals or gaskets at the same time, as these are often disturbed during replacement.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
