What it is

This is a sacrificial anode with an integral connection lead, supplied by Viessmann under part number 343F. It is fitted to protect the appliance's water-containing components from galvanic corrosion, and the connection lead allows the anode's condition to be checked electrically during servicing.

Signs this part needs replacing

  • Anode continuity test returns a reading outside the acceptable range
  • The anode body is visibly consumed, pitted or reduced in section
  • White or grey deposit build-up over the anode surface
  • Repeated or worsening corrosion-related issues in the appliance's water circuit

Before you order

  • Confirm the appliance model and serial number match the fitment listed
  • Check the existing anode's condition by continuity test before ordering
  • Verify the connection lead connector matches the appliance's test point
