What it is

The Vokera 20085974 is a gas diaphragm used in selected Vokera Easi-Heat i and Vibe Max appliances. It is a flexible component that responds to pressure changes within the gas valve, and it is renewed when it no longer seals or moves as it should.

Signs this part needs replacing

  • Unstable or fluctuating burner pressure
  • Appliance fails to ignite or repeatedly locks out
  • Erratic flame modulation or poor burner performance
  • Whistling or unusual noise from the gas valve
  • Visible splits, hardening or distortion on the diaphragm when inspected

Before you order

  • Confirm your appliance model matches one listed in the Fits section.
  • Check the part number 20085974 against the appliance data badge or the manufacturer's parts list.
  • Have the model and serial number to hand when checking compatibility.
  • Gas valve work must be carried out by a Gas Safe registered engineer.
