Hello all, First sorry for my bad English. I have a cnc plasma machine made by Pierce Control equipped with an HPR260XD, Few days ago everything was working fine. Today when I switched on my HPR unite, water started leaking from the torch, I replaced the check valve, solenoid valve, and the bypass valve. Same problem, water keeps leaking from the torch, also the reservoir whenever I turn on the unit, it starts bubbling and swelling. I tried everything yet the problem haven't been fixed! I contacted my machine manufacture support, they had no idea what causing this issue, they told me to replace the valve which I already did, so any one have an idea what causing this problem?! and thanks in advance.
