Error 2134 - Abnormal water temperature (TH6) detected.

What does 2134 mean?

The thermistor TH6, which monitors water temperature (inlet for BU), has detected a temperature of 85°C (185°F) or greater. This high temperature causes the unit to stop and enter a 3-minute restart delay mode.

• The pump is not connected properly or is malfunctioning
• A fault with the TH6 thermistor itself
• A disconnected TH6 thermistor connector

Click steps to track your progress.

1. 1

   Verify that the pump is properly connected and functioning to ensure adequate water circulation.

2. 2

   Check the thermistor connector for TH6 to ensure it is securely plugged in and not loose or damaged.

3. 3

   If the connector is secure, the TH6 thermistor itself may be faulty and providing an incorrect temperature reading.

4. 4

   A qualified technician should confirm the actual water inlet temperature and potentially replace the TH6 thermistor if it's faulty.

5. 5

   Ensure proper water flow and temperature regulation within the system to prevent overheating.
