So – Good news and bad news
On inspection the 2 grill elements look identical. Same shape, same connections, so I simply swapped them over to find out if the fault was the element.
Good news – the new top grill (old bottom grill element) no longer trips the RCD.
Bad news – The small fan behind the grill is now constantly on. This is not the big fan in the main oven – this is the one that circulates air around both ovens (cooling fan?) Normally it switches off after the oven has cooled down . Cant see any loose wires that I might have dislodged, and the procedure to swap the grill element was really straightforward
Any ideas
ok. Thanks Dave.
Element is fine after the RCD is reset.
switch on grill
wait 2 minutes – RCD trips
reset RCD
Grill fine after that. I can see its bright orange all around
If the element is faulty , would this happen? would it not just keep tripping the RCD?
Sorry – just trying to understand
Thanks Dave
I think its only the grill setting. I need to keep checking.
when you say a slight earth fault – is that a loose connection? or is that normally a fault in the element itself?
It switches on for a couple of minutes before it trips, so I wondered if it was some sort of thermostat issue i.e. when it gets to a certain temperature???
After reset, the grill heats up with no issue. Strange
MRB uprated to 32A. been fine for a few days, but now when top grill is switched on it trips the RCD after about 2 minutes.
It doesnt trip straightaway, but pretty much trips everytime on the grill after its been on for a couple of minutes.
reset the RCD and its fine, it doesnt trip again.
Any ideas?
Re: Bosch WFL 2450
ok, so based on Clives tips its the bearings.
On this particular model, is renewal fairly straightforward?
i.e are any special tools required?
Is there anything else I should change whilst I’m in there?
Thanks in advance
