My Candy C5006 electric cooker has one hob ring which when turned up to a high setting trips the electric fuse, all olther hob rings work ok.

It is likely the control board. You need a technician. They are expensive so you need the correct diagnosis and warranty on the work.

Hi, Try taking the back off (sometimes the have have clips)?

Unfortunately, Induction hobs on domestic cookers have always been a problem. A single, one ring catering hob is $1,200 and is expected to last 2 years in an industrial environment.

There are two videos here, but I reckon you will need a service call.

I am not familiar with your model of cooker but I assume it is a gas cooker.

Gas cookers have safety devices in the oven and grill the hob rings do not need. I speculate even the domestic oven hasn't escaped the interference from the electronics industry and I expect the aforementioned safety devices depend on (low voltage) electronics and electronics depend on electricity - that the lights aren't working would suggest there is no (low voltage) electricity.

Even in the case of an electric oven the thermostat could be electronic and need (low voltage) electricity to work.

I suspect the internal power supply has failed.

Hi, Have you altered the time clock on the cooker? It is possible that the clock/timer is set for 'Auto'

It is either a faulty ring, or the regulator that controls it is faulty.
You really need a meter to test the ring with to be certain which part is faulty.
Hope this helps.

Ours started doing the same Displaying L on four hob displays. I figured to press the bottom right hob and the minus button at the same time should unlock it.

Thanks

it will have nothing to do with the supply, although it does sound as though he could have done a better job. if the appliances are brand new get Zanussi out to it. shame on the guy for not checking that they worked as they should. hope this helps.

The symptoms you describe are a classic example of an oven element heating up, and as it gets hotter, the insulation is breaking down, thereby causing the earth leakage trip to operate.
To confirm this , switch on the oven, and turn all 4 rings on the top to full heat, 2 at a time, let them stay on for at least 10-15 mins, and if it does not trip, then you can be pretty sure it is the oven element(s) that is the problem

It is not likely to be the wall switch, as if it were faulty, i would expect the trip to go right away.
If you want to check further, then turn on the oven again and see if it trips, if it does ,then it is definately the oven element(s) that is the problem.

If it is a fan assisted oven , the element is at the rear of the oven, and possibly one under the base ot the oven. If it is a conventional convection oven, then there is an element at each side of the oven, even if one is faulty, replace both.

Plz rate my solution.
Thanks.
