What it is
The GW3-A5 is a pressure switch manufactured by EOGB and supplied as a replacement for the GW3-A2. It is used on EOGB Dungs boiler applications to sense pressure and signal the appliance control circuit accordingly. The part is listed under the EOGB Dungs model range.
Signs this part needs replacing
- The boiler fails to prove pressure and locks out or refuses to fire.
- Repeated lockouts or intermittent running that points to unstable pressure sensing.
- The switch no longer changes state when the sensed pressure changes.
- Visible damage, contamination or blocked pressure ports on the switch body.
- Fault codes or diagnostics on the appliance that indicate a pressure switch fault.
Before you order
- Confirm the existing switch is marked GW3-A2 and that the GW3-A5 is the stated replacement.
- Check the pressure switch is the correct item for your EOGB Dungs boiler model.
- Inspect any pressure sensing tubes and ports for blockage or leaks before fitting a new switch.
- Isolation of the gas and electrical supplies is required before any work on the appliance.
