What it is
The Alpha 3-way valve motor drives the diverter valve that switches the boiler between central heating and domestic hot water. It is a genuine Alpha part, number 1.028572.
Signs this part needs replacing
- The valve or motor fails to switch between heating and hot water, or is slow and noisy in operation
- No hot water or no heating on one circuit while the other works normally
- The motor hums but does not turn, or the cartridge is seized, sticking or leaking
Before you order
- Isolate electrical power and drain down the relevant circuit before removing the valve or motor
- Confirm the fault is the motor or cartridge itself rather than the signal driving it
- Match the part number exactly, as these assemblies are often revised between production runs
