Hello all,

So I have a Bosch dishwasher that kept tripping the fuse. Looked into it and bought a new motor/heat pump. Exactly the same model number etc. fitted it, ran a a cycle but doesn’t heat and I get an error e09 at the end of the wash which says heat pump failure. This is the first time I have had this error and also never had a problem with no heat before. Tried old heat pump and same thing.

Any ideas?
