Hi folks,

To cut a long story short the circuit breaker in my flat tripped earlier this evening. Unusual occurence as this has happened two or three times max in the 2+ years i've been here.

Baumatic B10 electric hob:

Anyways after a bit of resetting and switching things off and on i narrowed it down to the hob which was causing the breakers to trip.

However.........there is a twist.

After a bit of self diagnosis i've realised that the hob itself switches on and powers up as normal when you turn the dial. It goes onto power setting 1 and heats up fine. Turn the dial round one more click onto 2 and all is good. Turnit round one more click to 3 and off everything goes in house as the breaker trips (note the main breaker switch goes, not the individual switch for a specific room).

After further messing around with the four hobs i have found the issue to be consistent with all four of them having the same symptoms; ie all fine at 1 or 2 but onto 3 and it's adios. I have also had the four rings on in different combinations and also all on at the same time at level 2; again all fine but try and put the heat up to 3 or higher and it cuts right out.

Last used yesterday (Sunday 16th) and all working fine with all four rings used for cooking dinner with no probs.

The oven sits seperately from hob but they both run off the same big red 'COOKER' button which is set into the kitchen wall. Oven and grill both working as normal and i even rattled them up to max output (230c) to see if they cut out but thankfully they warmed up as normal.

Perhaps a lot of that is irellevant but trying to give as much info above as possible!

Any help or advice would be appreciated. Thanks in advance.

regards,
Steven.
 
The fact that it powers up , means that the fault probably lies withing a transformer meaning that there is a short circuit or a overcurrent fault within the windings of transformere, as its a RCBO there is no way to discriminate between the two without tests being carried out.

I am all for making repairs where appropriate but i cant stress enough that this IS NOT a diy matter so if you dont feel confident carrying out such tests then it probably isnt for you.

also i dont know what Baumatic are like for spare parts. as there will be some kind of transformer that wil need replacing, if it was simpy a wiring issue then it would trip on all settings
 
Thanks for the reply HighTower (spooky actually as i was watching police academy 3 last night after i posted this).

Further to the confusion this morning i tried it again and all four of them working as normal and go up to full temperature. Girlfriend then mentioned she might have "spilled a little water" on the hob yesterday before leaving for work.

If it happens again and turns out to be intermittent i know where to start with the transformer and will get a professional in to have a look - thanks again for the response.
