Samsung/Gen6 plumbed boiler (ASHP)

[Paul16461]

Two year old system, serviced annually has repeatedly shutdown with E911 error code. 
ASHP filter has been cleaned of debris 3 times (non ferrous). 
any ideas why this keeps happening every 3-4 days.  
thanks in advance.

Your system looks manky.

 

Delete the strainer and install a proper filter is step one.

 

Is system correctly inhibited? Not a fan of glycol if your system is filled with that. If not needs a suitable inhibitor and if a low temp system biocide.

I can't help with your question, but I've moved it to the ASHP sub-forum and mentioned that it's an ASHP in the title (I would generally assume a "boiler" is gas or oil fired).
