Bosch HBN70 keeps tripping the RCCB when temperature is reached?

hi, we have a Bosch HBN70 double oven which trips out the downstairs circuit breaker (RCD/RCCB) when using the lower oven, it only happens when it reaches the temperature and the heater is supposed to cut out.

after it trips out, we reset the RCD, and the oven can trip out up to 5 more times before eventually working as normal.

do we need an electrician, a bosch engineer, or could I fix the problem myself?

any advice / suggestions would be appreciated.

p.s. this has only started since the oven light went out - could that be connected?

thanks

Bosch Bosch HBN70 Kitchen Appliances, Electric Cookers Double Oven Trips

Buy a new fan motor and element and watch the youtube tutorials to see how easy it is to fit the parts yourself. Just remember to disconnect from power supply. If in doubt switch all the electrics off using your trip - no doubt you'll be familiar with that by now if it's been happening regularly for the last 2 years..!

Cost approx £100 - £120.

Call a proper engineer and dont mess with this, if its tripping the RCD, that generally means a fault to earth, you could easily electricute yourself if you dont know what you are doing
