What it is

The Soft Start Unit 7kW is a Worcester Bosch electrical component supplied for the Greenstore 7 appliance family. It controls the initial current drawn when the compressor starts, reducing the inrush load placed on the supply. It is specified for the SOFT Start variants of the Greenstore 7 Combi and Greenstore 7 System.

Signs this part needs replacing

  • The protective device trips or the RCD operates each time the appliance starts.
  • The compressor hums or attempts to start without running up.
  • Noticeable voltage dip, such as lights dimming, when the appliance starts.
  • Repeated start-up lockouts or the appliance failing to run through its start sequence.
  • Audible buzzing or clunking from the unit area during compressor start-up.

Before you order

  • Confirm the appliance is a Worcester Greenstore 7 Combi or Greenstore 7 System SOFT Start model.
  • Match the existing component to part number 87161134850 before ordering.
  • Check the appliance rating and the supply circuit against the 7kW rating of this unit.
