Steam Generator Issue. Call for service, you can't fix these yourself as they are fully computer controlled. Maintaining them is a cost of doing business.

you have a code that is not documented, phone their service department. It is probably just advising there has been a power outage.

So I found the service manual for this model.

https://www.rational-online.com/media/downloads/en-gb/manuals/rational-original-operation-manual-cmp-en-gb.pdf

The list of codes is on page 105. Code E34 is simply listed as contact customer service. Which is not really all that helpful in diagnosing the problem. Have you tried to reset the oven? Disconnect the power cord for 2-3 minutes and trying again? If this doesn't work, given the general code, you should call the customer service number in the manual.
Hope this helps.

Hi, error 12 is displayed when the oven pcb is too hot, check that the air filter is clear and the cooling fan is running. Also it could just be the software, if it is an older oven and has the original software then it may just need upgrading by someone who knows what he/she is doing.

Sounds like a bad relay

Most likely it is a blown heat element, you could check it if you have a multimeter or continuity tester.

Hi,
Before you go working too hard to get you oven to go into the self clean mode(self destruct)....check out this tip...

" Wish I had read this first. I never would have used the self cleaning option. Thanks for the info!!

Hi, It very well could be the ignitor. Sometimes they work at first and then will not open the gas valve later in cycle. You can set the oven to heat and watch the ignitor. If it glows and the gas will not ignite in 30 to 45 seconds, the igniter is getting weak. I jope this helps.
Please let me know if I can assit you further.
