E03 Fault Code — System Sensor — Стиральные и сушильные машины

HTP: Fault Code EO3 System Sensor Failure: This screen shows that there is a problem with the system sensor circuit. The circuit could be open or shorted. Possible reasons for this error are: There is no system sensor connected to the Master Boiler. The system sensor is faulty. There is a short circuit in the system sensor wiring; possibly from a staple placed through the wire, or damage to the wire causing both conductors to touch. The system sensor wiring is open due to defect or damage.

Disconnect the system sensor from the wiring and measure the resistance of it. Compare the measured resistance to the table in this manual to see if it corresponds to the temperature of the sensor. If the resistance does not agree with the sensor, replace the sensor. If the sensor is OK, disconnect the sensor wiring from both the boiler and the sensor and check continuity using an ohmmeter. Repair or replace as necessary.

If this error is present, all boilers in the cascaded group will run and ignite simultaneously when there is a heat demand. Each boiler will modulate to maintain set point temperature on its own supply sensor. This code will reset automatically when repair is complete. This code will not display if system setting function ERROR SYSTEM SENS is set to OFF
