Hi. I have a hotpoint aquarius AQC9BF7S1 uk. Have just pit a bew heater element in it as it was showing fault code f08 and wasnt heating up.
It now runs fine and heats up lovely however after 4 minutes on cycle it starts flashing error code f08 again (still works and has heat) then a few minutes later it stops working. Have checked condensor unit and filter. And have checked all wiring and connections.
Any help or advice on this matter would be great.
Many thanks in advance
