Description

Pressure Sensor Typ 505 Confort for Roca Boiler — Hydraulic Circuit Pressure Control

Original replacement for boilers of the Roca brand (also referenced by Fagor). The pressure sensor monitors the water pressure in the hydraulic circuit and sends the signal to the control unit to regulate the boiler's operation. If it fails, the boiler may lock due to low pressure or fail to start even if the circuit is in proper condition.

Common Symptoms

  • The boiler shows a low-pressure error even though the pressure gauge indicates normal values.
  • The unit locks or turns off intermittently without apparent cause.
  • The boiler does not start and the display indicates a pressure failure.
  • Unstable or incorrect pressure readings on the control panel.

Why Does This Part Fail?

  • Wear of the internal sensor due to continuous pressure and temperature cycles.
  • Calcium deposits that block the sensor inlet and alter the reading.
  • Pressure spikes in the circuit that damage the sensitive element.
  • Moisture or corrosion in the sensor's electrical connectors.
