elderly couple next door just told me theyre buying a new oven cos theirs keeps tripping the electrics. told em id be wanting to try a few things first, but they said that cos the chap is very ill, he cant be taking things to bits any more. and the cost of a call out plus possible parts means theyre buying a new one.

so......me being a nice neighbour said id try and save em a few hundred quid by finding out the problem 🙂

seems its only happened since his wife sprayed inside the bottom oven with mr muscle. so shes thinking shes got the electrics wet or something. doesnt sound right to me. should be able to use oven cleaner in an oven!!

its a double oven/grill type jobby, and apparently whatever they switch on, top oven, bottom oven or grill, it trips the electrics. the hob, which is also from the same 'main switch' but other side of a gangway, works fine.

so my plan is to isolate electrics in the morning, pull the oven out (fitted oven) and check for loose wiring, or anything damp. apart from that i cant think of owt.

can anyone else suggest owt? its a zanussi ZDA 55 if that means anything.

thanks

Maybe the oven cleaner has melted bit of the cable and its shorting on the casing

Totally OT now, did you get the latest mag ok, posted it Saturday

Sounds like a burnt out element. Should be easy to spot but getting to them can be a bit fiddly. They are cheap to replace, just take the old one into a oven spares shop and they'll match it.

i had a smeg double oven (never again) that would regularly blow one oven element and then trip our electrics. don't know if that helps at all.

Often you can access them from inside the oven, sometimes just sat there, sometimes behind a thin metal panel screwed/slotted in place. Take a torch. Otherwise, whip the oven out and start taking off panels.

looking at this pic on page 9 of [url= http://www.serviceforce.co.uk/pdfs/U01104.pdf ]the manual[/url] theres an element in each of the ovens. so am i right in thinking that if 1 element was knackered, then it wouldnt trip the electrics if the other one was switched on? (it trips whenever anything is switched on)

therefore it cant be the element? or am i sadly mistaken? 🙂

Glad it got there ok Dave, good issue I thought,enjoy 🙂

Went for cable because you mentioned no matter what you turned on it tripped. Watch those double ovens when you pull them out, bloody heavy and the repairers usually have a table ready to rest them on

Could also be worth checking out the oven lights, often if they go they can cause the RCD to trip. Do you know if the consumer unit has a RCD fitted?

i dont know how its set up yet, turin, but again, my limited knowledge would be ruling that out as itd only trip the once wouldnt it, when the light actually went?

the fact it trips the leccy whenever any part of the oven switches on seems to suggest a wiring prob to me. like i say tho, its limited knowledge 🙂

If the lamp has blown this can lead to the RCD tripping, not the normal individual circuit breaker. The same would happen if one of the elements have gone. Ive had a look at the manual for it but there is no trouble shooting advice.

Best thing to do is to check whether there is and RCD fitted

by that, do you mean it can blow the main trip, rather than the one just solely for the oven?

would it test out by removing the bulb maybe?

thanks

depending on the set up yes, its worth removing the lamp,if nothing else it starts the process of elimination, it should be easy to remove, according to the manual the cover is removed by pushing in and unscrewing.

Like I said it could be the element that has also blown and causing the same thing if its the RCD.

Depending on the set up the RCD could be the big main switch, or there could be two of the RCDs, just depends on how the house is wired. If its only the cooker that is going off its unlikely to have an RCD fitted and therefore unlikely that its the lamp.

If your happy/competent enough, when you take the oven out, switch the oven and hob off at the switch and also make sure the circuit breaker is off. If you remove the plate which covers the connections, there should be a series of spade connectors which lead out to various parts of the cooker. If your comfortable and keep a note of where they go, you can remove one at a time and see if you can isolate the fault.

caveat though, only do it if your happy to do so, and confident about it. If not then leave well alone and see about getting a domestic appliance repair person out and if they are reputable they should at least be prepared to provide an estimate of the repair. If you are anywhere near Edinburgh I can suggest one

did exactly as you said mate. and its pinpointed the element. cant actually see anything wrong with it visually, but by removing the spade connectors the oven doesnt trip when switched on. stick em back and it does.

so......matey said that he priced it up at £150 fitted, and at their time of life he'd rather just have a new one than fanny about replacing stuff as it goes bit by bit. oven 10 yrs old anyway. fair point, and theyre happy enough to have just got to the bottom of it. at least he got the peace of mind of knowing that he hasnt just spunked hundreds out when it was just a light bulb or somethings 🙂

thanks ever so much for your help

If you have managed to get so far as you have done without help, can't you just get a new element from t'interweb and fit it? I got one for our Beaumatic and it was only about £25 delivered and took minutes to fit.

A m_f said, new elements are cheap and usually available locally.

if it was me then yes i defo would. they seem quite happy at the thought of a new oven now tho. theyve got one on order that comes and will be fitted tuesday, so he said if anything was to change, then it needs to be quick. not sure id really know what to do and how to fit it really. i could have a quick shufty i spose and see what price they are, but id hate to cancel their new oven and then **** it all up trying to help 🙂

important thing is theyre happy and got peace of mind now 🙂

We've got a Zanussi double electric oven. We're on our 3rd element. When it blows it definitely trips the oven breaker in the box.

Fifteen minute job to replace, sourced our replacements locally via the t'interweb. Nearly bought a spare to put on the shelf for the next time it goes, apparently quite common with Zanussis.
