What it is
The Glow-worm 0020014174 is a flow sensor supplied for Flexicon and Ultracom appliances. It sits in the water circuit and detects movement and rate of flow, passing that signal to the appliance control board so the boiler can decide when to fire and how much output to demand. A failed sensor leaves the board without reliable flow information, which typically shows up as poor or intermittent hot water rather than an obvious mechanical fault.
Signs this part needs replacing
- Domestic hot water runs cold or only warms intermittently while the heating circuit behaves normally
- The appliance fails to fire on a hot water demand, or fires and then drops out shortly after
- Flow-related fault codes or lockouts appear on the control panel
- Hot water temperature fluctuates noticeably between draws
- The sensor body, connector or wiring shows contamination, corrosion or a loose plug
Before you order
- Confirm the appliance model and GC number against the compatibility information for this part number
- Compare the number on the existing sensor with 0020014174 before removing it
- Check whether the sensor is supplied with its sealing washer or O-ring, and order a replacement seal if the old one is disturbed
