Oven not heating
there is more to this than meets the eye if youre oven takes a long time on fan setting it may be thermostat but more likely to be fan not turning at all or quickly enough the stat capillary is above oven element and if fan not blowing air away from capillary oven stat will shut oven temp down too soon if using conventional heat eg no fan make sure there are no full size trays directly on bottom of oven this will block heat from bottom element effectively giving only half the heat output.
hope this helps

My Bosch HBN 5605 .0B oven has a 15-20 degree
I detected a similar problem following the sudden appearance of Err1 in the display. (Oven 4-5 years old, and the grill element failed when it was 3-4 years old). This indicated a temperature sensor problem. My local dealer came with his Thermocouple and confirmed an "under temperature" reading on the standard and baking settings. I agree that the fan setting is probably OK. He replaced the sensor. I monitored the situation for a while and was not happy because an under temperature could be quite dangerous when cooking certain foods, and also causes problems when baking bread.
The location of the oven sensor is also a problem because it is at the top right by the grill which also serves as the top heat source.
I had corresponded with Bosch about this and their response was, frankly, less than satisfactory. In the end I decided to call out their engineer (cost £85-ish) who wired my oven up to his computer. In the end he said that the oven was working as it should be (despite it taking a very long time to actually reach the target temperature of 200C.
In my view of I want 200C, then I should get 200C, not an approximation.
Interestingly the secret info (not in the manual) is that the temperature bar readout does not indicate that it has reached the actual temperature, but may be 90% of the temperature (so if you want 200C you get 180C.
An unsatisfactory solution is to get an oven temperature of the meat probe type and put that in the oven, then you will get a more accurate reading of the temperature. You would need one that goes above 200C (my first one only goes to 200 but I have found another that goes to 250C). Mine is by CDN model DTP482, any good cook shop should stock this.

My bosch oven grill element is not working and my
More than likely the grill element has failed, and this could account for the oven not getting hot enough, as on some makes, the grill element is on at the same time as the oven element, so if the element has failed, then it will not be hot enough.
My advice would be fit a new grill element, and this hopefully will solve the problem of the oven not being hot enough.
Please rate my solution.

Common heating faults with Bosch HBN 430560B / 430520B single oven
For all Free appliance repair videos visit our VIDEO
1, If the Bosch fan motor in the back of the oven is going round and
the temperature light is on (normally little red light), but there is no heat
then you will probably need a new oven element, these are generally very easy
to fit and readily available from our website these can be tested with a
To gain access to the BOSCH element you will
have to remove the back plate from inside the oven. Once removed you will see
the fan and element, if you
look closely at the element you will
probably see a small hole burnt in it where it has blown. Sometimes however
there is no evidence of a fault but the element
is open circuit ie:
broken inside the element casing, either way it will need replacing. Some
elements will are fixed from inside the oven and some are held in place by nuts
from the rear of the machine.
2, If your BOSCH fan
oven is getting warm but takes a very long time to cook or is burning the food
more on one side than the other, then you need to check if your oven fan motor
is working you will
see the blade turning fast if it is ok. if the element is heating but the fan motor is not blowing the heat into the oven then
you need To replace the oven fan motor
is a little more
expensive and a bit more involved.
3. If you have the opposite problem ie: your oven is over heating
and burning everything then you will need to replace your BOSCH oven thermostat
4, A quite common and easily overlooked answer is if your BOSCH oven is not working at all ie: no
heat and no fan then the chances are that someone has put the oven timer
into AUTO mode,
simply put oven back to MANUAL mode and all should be working again.
