Does this need to be hard wired on installation?

no -- the stove uses around 20 -30amps when in operation so a normal plug and leads are inadequate for the job
normal installation requires a hard wire through an isolator switch
be safe, pass the short cut, and have an accredited electrician do the job

Posted this several years ago. It's possible the oven sensor has gone bad or lost connection. Try cutting out the little plastic electric plug that connects the sensor to the oven wiring. Then hard wire it together with two small wire nuts.
If that doesn't work, you will need a new sensor, as we did. But when we installed it, we used the little plastic electric plug to connect it. Two days later it started acting up again.
The instructions said to hard wire it with two small wire nuts, but since it came with a plug it made sense to use it. Finally, even though it didn't make sense, I cut out the plastic plug and hard wired it. It's been about 3 years now and we've had no further problems.
THERE IS SOMETHING WRONG WITH THAT LITTLE PLASTIC ELECTRIC PLUG. YOU MUST NOT USE IT. HARD WIRE IT.

If your supply is 220v you can use it off a 13A plug. If 110V No.

The wiring should go to a cooker switch box...usually found at the back of an adjacent cupboard or on the wall. This will usually have a large red switch with a power indicator light and a standard switched socket.
On most installations of seperate oven and hob...the hob will be hard wired to the big red switch and the oven will be plugged in to the standard socket. So switch the socket off and see wether your oven is off...if the oven is connected to the big red switch instead then it must be hardwired...

Hello,

Welcome to FixYa.

You don't HAVE to hard wire, you can install a regular oven plug and receptacle outlet, but this is the recommendation of Bosch.

**Before installing the oven have a qualified electrician verify that your home is provided with adequate electrical service and that the addition of the oven will not overload the branch circuit on which it is to be installed. A separate three-wire or four-wire single phase, 240 Volt, 60 Hz., or a 208 Volt, 60 Hz. branch circuit is required.**

I'm not sure how clear this will come out when I post it, so if it is not acceptable let me know. I can send you the complete installation guide "pdf" via email if you post an email address.

I'll watch for your reply, good luck. Thank you for choosing FixYa today for your inquiry.

Your oven needs to be hard wired to a junction box. No plugs on a oven that pulls 30 or more amps 220v Read your install book that came with the oven.

Providing it is just a single fan oven on it's own. then it will work fine from a normal 13 amp socket.
If it is a double oven, then it will have to be hard wired into a cooker control switch box, protected with a 30amp circuit trip or fuse.
Please rate my solution to your query.
Thanks.

U need to open/unscrew back and look at bottom connections to the left ( looking from the back) Earth green and yellow- Blue is neutral and Brown is live you probably need electrical female spade connectors for your end of the 'hard' wire !!
