What it is

The Hamworthy thermostat pocket, part 531050013, is the pocket that carries the flow temperature sensor on the appliance. It is listed in the Hamworthy spares range as a single stat pocket and is used on Modumax and Purwell Variheat floor standing boilers. The pocket holds the sensor in position against the flow temperature so the control can read the water temperature.

Signs this part needs replacing

  • The flow temperature reading is unstable or reads low because the sensor no longer sits in firm contact with the pocket.
  • Corrosion, pitting or thinning is visible on the pocket wall.
  • Scale or debris has built up inside the pocket and stops the sensor seating fully home.
  • A weep or leak is present at the pocket joint.
  • The sensor has seized in the pocket and cannot be withdrawn without damaging the pocket.

Before you order

  • Confirm the appliance model against the fit list above.
  • Check whether the sensor itself is also damaged, as the pocket does not replace the sensor.
  • Match the part number 531050013 against the number on the old component or in the appliance manual.
