Siemans hb915506b Size of main oven in litres

Read off the power consumption of each oven and other equipment being fed from the cooker supply and have an electrician check the size of your cooker feed cable and main cooker breaker.
If the cable is not thick enough for the oven, you cannot increase the breaker size!
The breaker may of course be faulty, measure the current draw as the brealer trips.

As most building codes require Ranges/Ovens to be on an independent circuit, most do not have fuses installed. Chances are the element in the oven has blown out, leaving an open circuit, much like a fuse would. This would explain why everything else works, but that does not.

Hi, for the top oven:
Actual capacity 39 litres, Usable capacity 35 litres.

for bottom oven:
Actual capacity 59 litres, Usable capacity 50 litres.

That depends upon the mains voltage. 2.3KW at 240V = about 9.6A, which would want atleast #16 (AWG) or 30/0.25 (metric) wire. If your mains voltage is higher, you could use smaller wire. If your mains voltage is lower, you'd need larger wire.

Are you SURE your oven only uses 2.3KW? That sounds awfully low to me, barely more than a milkhouse heater.

Sounds like the amperage draw of the oven is right at the breaker size. Circuit Breakers should not be loaded more than 80%. Breakers take time to trip when they are close to the limit. IF the problem started with the replacement oven element, it may be the wrong one and could be tripping the breaker by drawing too much power.

Otherwise: Wiring or breaker not sized right, maybe another load on the breaker in addition to the oven, possible bad connections causing extra amperage, or wrong the oven element made for a higher amperage oven. In rare cases the breaker might be bad, but this is not likely.

Someone experienced needs to a) identify the breaker size b) verify the wire connected is appropriated sized c) verify the oven's current requirements and d) look for bad connections.

Normally another load would not be on the oven circuit unless a diy person changed the wiring. With those items verified, a clamp on amp meter would be used to verify actual current draw when the oven is on to ensure the load is appropriate for the breaker, wiring and oven. If at this point the load is less than 80% and the breaker still trips, change the breaker.

The recipe is the one to follow, NOT stove. And always in center rack of oven. Too low burns underneath, too high burns top

It requires a min of 6mm twin and earth to be used from the main control switch to the oven

either a siezed washmotor that can be freed or will need replacing... sorry

Phoned siemans direct and they are sending me an instruction booklet in the post

I havent solved the problem and I dont want to pay to find out the litreage of the oven.
