Hello HRSPWR,

So i did replace the seal kit for the regulator although others said too replace as is instead of wasting time but due too new regulator being around £500 it was worth a punt on the £85 rebuild it.

Unfortanlty it didnt work, so company have ordered replacement regulator for the machine.

As an odd issue the sister machine in same location doing the same daily jobs has just failed and doing the same issue. Removing the gas filter was extremely clogged with debris even been cleaned 6 months ago..

So now were led too believe could be issue with the gas there being supplied causing issue "dirty gas causing blockages/issues?

Thanks
