Thanks for that. Good news and bad news im afraid. The good news is it can be repaired if the back wall isnt spongy but the bad news is its not a cheap fix.
As the compressor is hot and theres no cooling in the fridge then this is going to be a system fault. Its more then likely a blockage in the system but it could also be a faulty compressor.
But for this fault you will need to get a fridge engineer in as it isnt a diy repair. They will need to put there gagues on the pipe work at the back to see what pressure the compressor is pumping at.
Now the cheapest option here is to get Hotpoint in on there fixed price repair. They do a fixed fee for £110 all in so no matter what it needs they will fix it for that price.
So they will call out and check it out. If its a blockage in the system they can then clear out and regass it from there or if the compressor has failed they can replace it.
This way will be a lot cheaper then getting a local engineer in as a regass from them is around the £150 mark.
Sorry its not good news but if you need anymore info just get back to me.
As to being a member then its not showing up as that as it just shows as a one off question. Its just giving you the option i think so if you dont want it just ingore it as its just a one off question that yo have asked.
