What it is

The Ideal 181131 is a complete hydroblock kit for the Ideal Logic CODE Combi Esp1 26 combination boiler. The hydroblock assembly carries the boiler's main water circuit components, handling the flow of water between the heating and hot water sides of the appliance. This kit is specified for AFQ code or later builds.

Signs this part needs replacing

  • Water weeping or dripping from the hydroblock body or its connections
  • Loss of system pressure that cannot be traced to any other component
  • The boiler failing to switch correctly between heating and hot water
  • Whining, grinding or unusual noise from the hydroblock area
  • Seized or stiff operation of the diverter section, affecting hot water delivery

Before you order

  • Confirm the appliance is an Ideal Logic CODE Combi Esp1 26
  • Check the boiler's GC number against your appliance data badge
  • Check the build code on the appliance to confirm it is AFQ or later
  • Verify that the complete kit is required rather than an individual hydroblock component
