What it is

The Sime 14 pole cable is a wiring harness used to connect the CN15 and CN5 plug connectors within Sime Murelle PRO HE boilers. It carries control and signal wiring between the boiler's electronic assemblies. The part is listed by Sime under reference 6325603.

Signs this part needs replacing

  • Fault codes or lockouts traced to a broken connection between the CN15 and CN5 plugs
  • Visible damage to the cable, such as chafed, scorched or brittle insulation
  • Loose or intermittent contact at either connector causing erratic boiler behaviour
  • Cuts or breaks in individual conductors found during continuity testing
  • Corrosion or heat discolouration on the plug terminals

Before you order

  • Confirm the boiler model and serial number against the fitment list above
  • Check the existing cable's pole count and connector layout match this part
  • Inspect the CN15 and CN5 sockets on the board for damage before fitting a replacement cable
  • Isolate the appliance from the electrical supply before removing or refitting the cable
