Update on the above

Having gone back and tested everything (again) I have now replaced the fans and both boilers appear to be running fine. There was no issues with reverse polarity. Having inspected both fans there is evidence of water damage to both of these units. I contacted Wolf in Germany and they informed me that water damage to the fan is one of the most likely causes (which seemed to be the case). Having spoken to the owner of the property he did have the flue openings sealed up a few months ago so before this there was possibly an issue with rain water running down the outside of the flue and on to the top of the boiler and eventually making its way inside the case and dripping on to the fans as there is evidence inside the boiler (mainly the first one that went) that this was the case.

SO! fingers crossed, they will be back in working order for a few more years.

Many thanks to all that helped on this

John
