Hi Rich

 

 

if your Bosch HBN331W0B Single Oven is not heating or tripping the electric supply there is a good chance that one of the elements has blown. I have included some videos below to help you test and then replace the element. Also I have include a link here for list of parts for your Bosch HBN331W0B cooker.

 

For your future reference I’ve included some Common faults with these Bosch HBN331W0B cookers to assist you in the future or anyone else reading this.

  • The oven will not turn on
    The first thing you need to check is that the oven timer is not on auto if it is turn it on to manual.
  • No Heat in Oven
    If the fan is running and the thermostat light comes on but you get no heat (or just the thermostat light on in non-fan ovens and cookers) then the probability is that the fan element or oven elements have failed.
  • Electricity trips (Rcd) when I turn the oven on or grill
    This is normally an element that has gone to earth, This is a well-known fault with electric ovens, the insulation breaks down in the elements and trips the RCD , best way is to stick a meter on each element and check that they have not got earth leaks on them. But this can also be a wiring fault.
  • The grill element doesn't work
    This would usually indicate that the grill element is faulty. Check these: Grill element, Oven changeover switch, Overheat thermostat, Main oven thermostat, if used to regulate the grill temperature.
  • The oven fan is not working or spinning correctly (slow) or is noisy
    The fan motor may need to be replaced see video on this also the cooling fan motor can cause same problems.
  • The oven overheats and burns everything
    Normally this is a simple thermostat failure which would manifest itself as this symptom.
  • The oven or cooker cuts out after it's been on for a while
    This is an overheating problem which can be caused by the fan motor or main oven thermostat or a faulty safety thermostat that will be causing the problem. It can also be caused by a failure of the cooling fan, where fitted, but usually these go noisy before failing, Safety thermostats are used to prevent the oven or cooker overheating and will shut the oven down.

If you need any more help on this oven feel free to send me an email or use the live chat. All the best Paul.

    Hi
    I have a Bosch HBN131560B single oven that is approx. 13 years old.
    It stopped working (generating heat) suddenly a couple of days ago after using the grill. Neither the grill nor the main oven elements are working.
    The thermostat light comes on even when the temperature is on 0 (zero). The fan in the oven (inside the heating element) does not work, nor does the internal light but the display does not show any error code or anything abnormal. The other fan (that blows air above the door) does come one when oven is on.

    I am really struggling to establish what part could be faulty… the safety thermostat maybe?

    Any assistance would be welcome.

    Didier
