hi there
Mine recently froze up. I replaced the interior high pressure hose which had burst. The 240V pump seems good.
I have to hold down the float in the float chamber to fill it up before it builds up enough pressure to jet water out of the lance. The burner kicks in and smoke comes out the exhaust but the water's cold even on max temp. Water sometimes jets out of the junction of the cylinder head and the pump on the left hand side, by the high presure hose outlet. I have to retighten the cylinder head to stop it. This suggests to me some sort of blockage from the head out the lance. The pressure guage on the head is permanently stuck at 100Bar, machine on or off.
I can't seem to get hold of a service manual, only an operations manual. Replacing each part by a process of elimination will be too expensive so I'm looking for some sort of checklist. I assume that the service manuals are available only to dealers? Any help appreciated.
