My lofra cooktop is locked & have tried all the suggestions of turning off at switchboard e.t.c & it remains locked ??

Two things to try. Either unplug it or turn it off at the breaker.. Clean the cook top control area and allow it to dry overnight. You can turn the power back on after cleaning ideally. In the morning, with the power resumed just wipe the control area off with your bare clean hand.

I have no idea why this worked for me, but it did. Good luck.
If that fails, you can look up error codes or schedule a repair.

might be transformer noise? try turning the cooktop circuit off at the electrical main switchboard.
or get your wife to stop singing opera!!

try turning power off at electrical main switchboard for a minute, then back on. reset clock and see how it goes.
otherwise > call the repair man.

lofra oven doesn,t turn on

had exactly the same thing happen; did you figure it out?
Would like to know if you had a big fee as won't bother if it is expensive to fix! Thanks Emma

There are two reasons for the lock to remain locked. One: the thermostat/wiring failed. This results in the oven's control still believing that the oven is too hot (over 450 degrees) and thus will not unlock. The other possible problem is that the unlock mechanism failed.

You can try to unlock the oven manually. (For some ranges, you can do this from the back of the range.) Please add a comment with the model of the oven/range for more assistance.

I hope this gets you started on solving the problem.

STRANGE THAT ALL YOUR VALVES WOULD GO BAD AT SAME TIME, I WOULD PERHAPS CHECK YOURKNOBS ( USUALLY THERE IS A SMALL METAL INSERT THE PRTECTS THE PLSCTICKNOB ITSELF, IT SOETIMES SLIPPS OF AND REMAINS ON THE VALVE STEM IF SO YOU WONT BE ABLE TO PUSH IT DOWN TO TURN IT ON, SIMPLY REMOVE THE INSERTS FORM THE STEMMS AND REINSERT THEM INTO THE KNOB IF THIS DOE INDEED SEEM TO BE THE ISSUE, OTHER THEN THAT REPLACING THE VALVES.

It sounds like the selector switch is shorted, the only way to fix that is to replace the switch

always unplug electricity before working on any electrical appliance

It is child lock.

Turn cooker on, press two + at front of oven, this will then take it off for that cooking session.

To turn child lock off switch on hob, and touch - for 5 seconds.
