The Electric Cooktop Does Not Turn On

There are several solutions for this problem:

  • The Electric Cooktop may not be plugged in. Check to see if it is plugged in.
  • The main switch is turned off. Make sure to turn the unit on.
  • Check to see if you are experiencing a power failure.
  • The power may not be flowing to the socket. Check if there is electricity in the outlet in question by using another small object that runs on electricity (e.g., hair dryer). If there is no electricity in the outlet, consult an electrician.
  • The fuse may have blown or the circuit breaker tripped. Replace the fuse or reset the circuit breaker.

The Domestic Fuse Has Tripped

Check whether the residual-current-operated circuit-breaker (FI) or the domestic fuse for the electric circuit has tripped. The main fuse and residual-current-operated circuit-breaker (FI) are for your safety and respond if there has been an overload or short-circuit in the electric circuit. Check whether other appliances in the electric circuit caused an overload. If required, contact an electrician.
