Worcester Bosch 2964 B Error Code

Описание: Worcester Bosch 2964 B Error Code explained.

If your Worcester Bosch boiler is showing the 2964 B fault code, this means there is a short circuit detected on the flow temperature sensor (thermistor). This sensor measures the temperature of water leaving the heat exchanger so the boiler can control heating safely.

When the thermistor or its wiring fails, the boiler receives incorrect temperature readings and shuts down to prevent overheating or damage.

In this video, BeFix — Reliable. Local. Gas Safe — explains:

• Corrosion in the thermistor connector

• Or PCB signal errors

⚠️ If the 2964 B fault returns after a reset, the boiler should not be run until inspected by a Gas Safe engineer.
