Mid position Honeywell stray/ghost current 60v

[Jon doc]

Turning into quite a common problem and seeing it more and more,  I know replacing the Honeywell for a Drayton eliminates the stray 60v as the latter only leaks about 20v...

but my question is...

Rather than replacing, what is the danger of fitting a suppressor between the switch live and neutral to soak up this stray current?

reading up on suppressors they seem to be geared more towards protection from spikes,

this isn’t a spike, it’s a constant 60v that would rise to 200 plus if I was to remove it from the load (swl connection at pcb)

Any ideas?  
main concern is how this type of protection fails..  short,open ect...

cheers

What are you measuring this 60V with?

The only time that I've had a problem like this is when I've seen evidence of a water leak

I personally hate 3 port mid position valves, but that is another story.

In a standard setup where the switched output is used to fire a boiler any stray leakage is irrelevant So what is it connected to that is getting bothered?

And Honeywell are usually reckoned to be one of the best, with Drayton next and Danfoss at the bottom of the heap imho.
