What it is

This is the X9 cable wiring harness manufactured by Viessmann, part number 7823825. It is the internal loom used on Vitodens WB1A combi boilers built from 14.01.2005, carrying low-voltage control and sensor connections between the boiler's electrical components. The harness is specific to this appliance family and build period.

Signs this part needs replacing

  • Intermittent faults, lockouts or error codes linked to control or sensor wiring
  • Heat damage, brittle or cracked insulation on the harness
  • Chafed, trapped or severed conductors on the loom
  • Corroded or loose connector terminals at the harness plugs
  • Boiler failing to fire or respond correctly after wiring disturbance

Before you order

  • Confirm the appliance is a Vitodens WB1A combi and matches one of the listed serial numbers
  • Check the boiler build date is from 14.01.2005
  • Inspect the existing harness connectors for damage and confirm the X9 designation
  • Verify the fault is in the harness rather than at the connected component
