What it is

The left hand hydraulic block is a component of the diverter valve assembly on Ariston Combi A series boilers. It carries and directs water through the hydraulic section of the valve, supporting the changeover between domestic hot water and central heating. This part is supplied by Ariston under part number 61315510.

Signs this part needs replacing

  • No domestic hot water, or hot water that runs cold shortly after draw-off
  • Domestic hot water temperature fluctuating or failing to hold steady
  • Heating running when only hot water is demanded, or the reverse
  • Water weeping or staining around the hydraulic block or diverter valve body
  • Radiators staying cold while hot water is drawn, or poor changeover between modes

Before you order

  • Confirm whether your boiler requires the left hand or right hand hydraulic block
  • Check the boiler model against the Combi A 24 MFFI and Combi A 30 MFFI listings
  • Establish whether the appliance was built before or after April 2006
  • Match the part number 61315510 to the number on the existing component
