I can't switch the fryer on. What is wrong?
Possibly the control panel has not been mounted correctly. You should hear a click when assembling it onto the fryer. The thermal safety cut-out may also have switched the appliance off. If this is the case, set the on/off switch to 'off', let the oil or fat cool down and press the 'reset' button at the back of the control panel. You should then be able to use the appliance again.
