What it is

The Potterton Mixing Motor G1/2 Inch SSC619 is a mixing motor for Potterton Commercial boiler appliances. It is listed for the Potterton Commercial Sirius SAT range and has a G1/2 inch connection. The part number is SSC619 and the SKU is 5138693.

Signs this part needs replacing

  • The mixing valve does not move when the boiler changes flow temperature demand.
  • Flow temperature remains too high or too low despite changes in demand.
  • The motor runs without moving the valve, or makes unusual noise.
  • The boiler locks out or fails to modulate correctly during a heating or hot water cycle.
  • Visible damage, overheating or water ingress is present at the motor housing.

Before you order

  • Confirm the existing motor is marked SSC619 or the boiler is a Potterton Commercial Sirius SAT model listed above.
  • Check the valve connection is G1/2 inch.
  • Inspect the valve body for seizure or debris before fitting a motor; a motor cannot correct a mechanically stuck valve.
  • Check the boiler model and serial plate to confirm compatibility.
