What it is

The 0010028086 is a printed circuit board for Vaillant boilers, built as the Type 3, 2-relay variant. It is the boiler's central control, running ignition, pump and fan via the appliance's sensors and switches, and enforcing safety shutdown on fault. This is a refurbished, tested unit.

Signs this part needs replacing

  • Boiler will not ignite or repeatedly locks out
  • Display or controls become unresponsive
  • Pump or fan fails to activate on demand
  • Intermittent faults or resets

Before you order

  • Confirm your boiler needs the Type 3, 2-relay variant specifically - Vaillant PCBs come in different relay/type versions for the same model range, so check against your existing board or serial number
  • Isolate the electrical supply before removal
  • Fitting must be carried out by a Gas Safe registered engineer
