BEKO DVC 665 s Electric Cooker GOOSED

I have a Beko DVC 665 s electric cooker and it’s goosed 👿 👿

I bought the cooker 14 months ago for £369 in the sales. Its been playing up for the last few months tripping the electric. It started with the back ring making a funny crackling noise, then kept tripping out and sometimes tripping whole house. When the cooker trips it makes a bang sound.

I doesnt do it all the time, but now the 2 back rings dont work at all and one of the four little lights that tell you the cooker rings are hot doesnt work. The light near the hob dial also flickers ❓ ❓ ❓ ❓

Totally gutted cos I dont have an extended guarantee and mine has ran out, although problem started when still In guarantee I never reported it 👿 👿

I wish I would of came on here before purchasing a BEKO product.. ❗

Any suggestions as to how costly the repair might be cos Im just thinking of skipping it and buying a new one…dont want to be ripped off by engineers.
