To turn the control lock its as below.

Turn the hob on so it shows L

Then you need to press the - and the front right + buttons at the same time

Then press the - button again and that should turn the lock off.

Try that and see how it goes. now it may not do it first time so try it a few times and see how it goes from there and let me know.

Should it flash Er03
It flashes up and once I let go to press the minus key it blinks of an the hob goes off and when I turn it on it's still locked with the L
UK Appliance Technician: Daniel, Home Appliance Technician replied 10 months ago

E03 is a fault on the electronic control board im afraid.

So if its not unlocking and flashing the er03 then im afraid its looking like the control board is the fault here.

One thing you can try if you havent is turn the power off to the hob and leave it off for 30 minutes as this can discharge the capaitors on there and can sometimes do a hard reset.

Then turn it back on and see how it goes from there.

If still the same then im afraid its looking like the control board itself in there is the fault and will need to be replaced on this.

Can the control board be replaced without having to buy a whole new job unit
Customer reply replied 10 months ago
Hob unit I meant
UK Appliance Technician: Daniel, Home Appliance Technician replied 10 months ago

Yes it can be but it isnt cheap. You are looking at £140 just for the board im afraid.

Is there anyway that you can do the reset other than just turn it off and is this a comman problem any idea what might have caused it
UK Appliance Technician: Daniel, Home Appliance Technician replied 10 months ago

Theres no reset on these. Just sometimes turning it off can discharge the capacitor and do a bit of a hard reset.

Control boards do fail on these hobs so its not uncommon for them to fail. As to what caused it then it can just fail without doing anything to it.

UK Appliance Technician: Daniel, Home Appliance Technician replied 10 months ago

Ive tried that again today it is flashing, Er22 now
UK Appliance Technician: Daniel, Home Appliance Technician replied 10 months ago

ER22 means ''Key evaluation defective, control cuts off'' Basically this is a control unit fault. The service manual states for the er22 fault the control board is faulty and will need to be replaced.

Basically all the faults you have here is all pointing towards the control board im afraid, Sorry
