What it is
The Alpha 1.5720 is a diverter valve motor used on the Alpha Wall Hung Flowsmart 50 gas boiler. It drives the diverter valve, moving it between the heating and hot water positions so the boiler directs water to the correct circuit. The motor is the actuator that operates the valve; the valve body itself is separate.
Signs this part needs replacing
- No hot water when a tap is opened, with the boiler continuing to serve heating
- Radiators heating up when only hot water is demanded
- Diverter valve failing to move between the heating and hot water positions
- Boiler locking out or displaying a fault when hot water is requested
- Motor body running hot, noisy, or failing to turn the valve spindle
Before you order

- Check the part number on the existing motor matches 1.5720
