We recently purchased a new freestanding cooker from John Lewis. An AEG 49332i-MN with Induction hob which my wife was delighted with!
The cooker is hardwired direct to a Crabtree consumer unit with a main RCCB 80A 30mA – Via a B40 MCB switch, cooker switch on the wall to junction box behind cooker then to cooker. The house is 16 years old and the old cooker never used to trip the electrics.
Straight from day one our electrics ‘tripped out’ randomly 2 to 3 times a day ONLY IN STANDBY MODE with no elements turn on whatsoever JUST THE CLOCK illuminated and working. It will trip at 2am in the morning when we’re all tucked up in bed.
We had John Lewis cooker repair man out to check the possible faulty cooker.
He found NOTHING WRONG with the cooker and said that when the cooker is in standby the clock does not use/require an earth on the circuit board at that stage.
He suggested replacing the wall cooker switch – which I did – It didn’t help, the electrics still tripped out. So I bypassed the junction box at the back of cooker – still didn’t help. I then wired the cooker straight to the consumer unit and replaced the cooker MCB with a new one. That didn’t help.
The electrics have NOT tripped at all when the cooker is NOT connected and NOT in standby. And have not tripped when we actually use the cooker whether it’s the hob or the ovens. It has tripped a few times when I have turned it off at the wall after cooking tea but 99% of the time is when it’s in standby mode.
So 2 weeks later, it was finally swapped for a new cooker. Problem solved we thought – it lasted about a day and a half and it tripped again!
Does anyone have any idea what’s causing this? My wife loves this cooker but turning it off at the wall and not using the timer is not really an option with a new cooker. Any ideas as to solving this issue would be gladly appreciated.
I also want to say that John Lewis have been brilliant about this and can only praise their after-sales service.
