What it is

The WPA adaptor with thermistor is a Navien component used on NPE-AWE and NPE-SWE series condensing appliances. It forms the connection point at the water pipe assembly and carries an integral thermistor for temperature sensing. The thermistor signal is used by the appliance control to monitor water temperature at that point in the circuit.

Signs this part needs replacing

  • Temperature readings at the appliance display are erratic, implausible or absent.
  • The appliance locks out or faults on a temperature sensor or water temperature error.
  • Visible weeping, staining or scale build-up at the adaptor joint.
  • Corrosion or cracking on the adaptor body or its threaded connections.
  • Damaged or chafed thermistor wiring at the adaptor.

Before you order

  • Confirm the appliance model and serial number against the manufacturer's parts list.
  • Check the adaptor body and thermistor plug for physical damage before removal.
  • Isolate the water and power supplies and depressurise the appliance before work.
  • Have new sealing washers or O-rings to hand if the existing ones are disturbed.
