Genuine Ariston replacement domestic hot water (DHW) 3-way diverter valve spring kit, part 65100541. Fits the Ariston Microgenus HE 24, 28 and 32 combi boilers. Restores correct switching between heating and hot water circuits.
The Ariston 65100541 is a genuine replacement DHW (domestic hot water) 3-way diverter valve spring kit for the Microgenus HE combi boiler range. The diverter valve is the component within a combi boiler responsible for switching between space heating and domestic hot water modes, directing the flow of heated water to either the central heating circuit or the hot water plate heat exchanger. A failing diverter valve spring typically causes the boiler to produce hot water but no central heating, central heating but no hot water, or intermittent switching between the two. The spring kit contains the internal spring components that provide the mechanical switching force within the diverter valve body. Note that this kit covers the DHW-side spring mechanism; confirm the specific valve assembly before ordering.
This is the correct replacement when the diverter valve is sticking, failing to return, not fully diverting, or causing temperature fluctuations due to weak or fatigued internal springs.
The kit is a direct‑fit Ariston component, matching the original spring rate, length, and seating profile for precise valve operation.
Key Features & Benefits
Ariston diverter‑valve springs - ensure correct mechanical force and smooth valve travel
Direct replacement - fits OEM 3‑way valve assemblies with no modification
Restores correct valve switching - eliminates sticking, partial movement, and mode‑change delays
Precision‑rated spring tension - ensures consistent performance under repeated heating cycles
Improves DHW/CH stability - prevents temperature swings and intermittent hot water
