What it is

The left hand hydraulic block is a Chaffoteaux component used on Minima Mx2 gas boilers. It forms part of the boiler's hydraulic assembly, where it directs water flow between the heating circuit and the domestic hot water circuit. It is listed under diverter valve spares for this appliance family.

Signs this part needs replacing

  • Domestic hot water runs hot and cold, or fails to reach temperature, when a tap is opened
  • Heating operates when only hot water is demanded, or hot water is produced when only heating is demanded
  • The diverter mechanism sticks, seizes or fails to move between positions
  • Water weeping or dripping from the hydraulic block body or its seals
  • Scale or debris build-up inside the block restricting flow through the assembly

Before you order

  • Confirm the boiler model matches one of the Minima Mx2 variants listed above
  • Check whether the failed component is the left hand or right hand block, as the two are not interchangeable
  • Verify the part number 61312303 against the markings on the existing component or the manufacturer's parts list
  • Inspect the surrounding seals and connections for damage before refitting
