Is the evaporator inside the freezer just building up with to much ice?
Also lets try an auto test and see what happens.
Open the fridge door and keep it open.
Turn both the fridge and freezer to the off position
Press and hold the super freeze till the leds come on.
Now after a few seconds 2 leds will go out and the power light will be lit.
It will run an auto test for about 5 mins. If it picks up a fault it will stop and flash some lights. If it does let me know which lights flash or lit up.
After about 5 mins it will stop so then you can turn it back on.
Let me know what happens.
Ok thanks for that. That error code is F06 which means the defrost heater triac short circuit.
The triacs are on the control board itself and as you have replaced the defrost heater already im afraid you re looking at a faulty control board im afraid at the top.
Now the bad news. These control boards are sold blank so if you buy one it needs programming so you also need to buy the card reader and smart card as well. Now the card reader and smart are about £90 for the reader and £20 for the smart card. plus the cost of the board which is roughly about £100 so its not a cheap repair.
The cheaper option here is to get Hotpoint in to fix on there fixed price repair which I about £110. This includes all parts and labour as they will use there laptop to program the new control board up. This will be a lot cheaper then you doing it yourself im afraid.
Its the way Hotpoint do it now with there control boards. There are all sold blank so you need the software to do it. Its only worth buying the card reader if you are doing quite a few control boards. For a one off its just not worth it as Hotpoint will call out and replace the board cheaper.
If you need anymore info just get back to me.
