The part which you have selected is a Ariston Motor + Spring 3 Way Valve Kit, and is designed to fit Ariston E-Combi ONE 24/30 combination gas boilers.
Ariston Combi 3-Way Repair Kit is the part that allows the water in your combi to be separated, which is called three-way, and ensures that the heater does not work when you only run hot water. In other words, it is a piece made in order not to have to turn on the heaters when you want to use only hot water. The part in this part is called the repair kit. Replacing the repair kits allows the three-way valve to be repaired and prevents hot water mixing into the pads.
