What it is

The Vokera low tension cable, part number 20038366, is a wiring harness used on Vokera Unica i28, i32 and i36 boilers. It runs from the CN2 connection to the water pressure switch, flow meter and DHW NTC, carrying the low voltage signals between these components and the appliance's control. It is a service part for the Unica range, including ERP variants.

Signs this part needs replacing

  • Intermittent or erratic readings from the water pressure switch, flow meter or DHW NTC
  • Fault codes or lockouts that clear when the harness is disturbed
  • Damaged, corroded or loose plug connectors at either end of the cable
  • Chafed, cracked or heat-damaged insulation along the cable run
  • Boiler failing to register a DHW draw-off or losing pressure signal during operation

Before you order
