Technical description

The external switching contact has opened

What causes this fault?

This fault occurs when a safety device connected to the boiler’s control board has broken the electrical circuit to stop the unit from running. The most common reason is a blocked condensate pump that has reached its limit and sent a signal to prevent an overflow, or an external thermostat that has malfunctioned. Essentially, a secondary safety device has stepped in to shut the system down for protection.

This fault is frequently seen during cold snaps when external condensate pipes freeze, causing the pump to backup and trigger the safety switch.

Engineer required

This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
