What it is

The Potterton Pressure Switch Kit is a service component for the Potterton Promax 24 Store range of unvented cylinders. It is listed under part number 7647881 as the kit pressure switch ErP. The pressure switch monitors pressure conditions within the store and signals the appliance control circuit accordingly.

Signs this part needs replacing

  • The store cylinder fails to fire or locks out on a pressure-related fault
  • Intermittent operation when there is a call for heat or hot water
  • The appliance does not respond to demand from the cylinder
  • Repeated fault codes or resets linked to the pressure circuit

Before you order

  • Confirm the cylinder is a Promax 24 Store ErP model
  • Check the serial number ends in BC
  • Verify the cylinder capacity is 90L, 115L or 150L as applicable
  • Compare the existing component against part number 7647881
