Bosch Dryer E51 fault

[pmb]

Good morning
I have a Bosch WTH84000GB/06 dryer which is displaying E51.
I must admit my knowledge of Heatpump dryers is lacking.
I have not been to this one yet as I could not find a meaning of E51, can anyone help me out with some tips please?

Last time saw this dryer the condenser had a decent amount of fluff inside, I cleaned away what I could but the stuff that was deep seemed inaccessible.
I looked at stripping the condenser down on an older version and it looked like the housing did not come apart without breaking the clips that hold it together.
Thanks, Darren

google search bring up possible motor triac fault

That would be obvious when you start it you will just hear the relays clicking and the power modules on these do fail they are easy to fit aswell

Thanks for getting back to me, I appreciate the advice.

I went to this one earlier and it turned out to be a E56 fault ‍♂️
I tightened all the wiring connectors and it worked for me.
I did notice some pitting on the square chip on the Power PCB though so I am not sure if it will happen again, I’ll have to see.

E56 is a communication error between power module and interface module it sounds to me like the power module fault as e51 is a motor wiring or motor fault
