New bosch hob tripping RCD 70V between case and earth if you disconnect the earth on the hob and test between the two
ERN:PKE611D17E /01 FD9502
Earth has been tested I even tested the case (with earth disconnected) to the earth on the ring main at that showed the same voltage.
Live to earth 230v with the cable taken out of the hob and tested.
I am a qualified Electrician but not have done a lot with white goods, the Consumer unit has just been installed 17th edition with two rcd's just wondering if you came across this before.
Normally this would only happen if the interior earth on the appliance failed or if the earth circuit of the property was defective at the point of connection or further.
Problem is, if you open it up to check the earth and find a defective element or something else, you would have invalidated your warranty to get it repaired/replaced
Thanks every thing works ok ,washing machine ,dishwasher shower etc. just the hob trips it .Thanks for advice have been on some forums and this has happened before due to a RCD being installed .
all they say all other appliances may be eating into the tolerance of the RCD ...One even said the service engineer got a belt of a case (80V) on the case..
No only if the hob is connected..
If the hob is disconnected, you need to put an insulation tester on the feed cable to the appliance. Neg on earth, and live on both neutral and live together, or separately.. Something like a 500v megger would do the jobLet me know what readings you get
