Which one of the following faults causes coffee in a Brewer to keep boiling after brewing cycle is finished?

The cause of coffee in a brewer to keep boiling after the brewing cycle is finished can be due to a faulty thermal fuse.

- The purpose of the thermal fuse is to prevent overheating of the Brewer.

- When the set temperature is reached, the fuse melts and interrupts the circuit, shutting off the power supply to the heating element.

- If the thermal fuse is faulty, it fails to melt and disconnect the power, leading to continuous boiling.
