Pro pressure washer 3200psi will only pump soap if lance is disconnected?

SOURCE: Karcher pressure washer won't start

Dear ralph_birtwi,
Most pressure washers when their gun is released, the machine stops automaticaly. This is done ny means of a control valve. When the gun is closed...pressure is built and the control valve moves and switches a micro switch off. In your case the micro switch is still closed in off position. Now this happens if a machine is left and stored with pressure in it., This control valve could get jammed and leaving the micro switch in off position. It could also stay in off position by sticking, due to incorrect chemical.
So the control valve or even called spill valve, must be renewed.
Sometimes a little lubrication with the right type of silicon grease will get the control valve working again. This job is sometimes delicate and better done by a qualified technician.
Regards,
fulltech.

Hello:
Best to use NON DETERGENT 10W30. Be sure you fill the reservoir only 1/3 to less than 1/2 full.

It sounds like the (RMW 2.2 G24) pump has gone out. Mine had this problem after about 6 hours of use. I was able to order a new pump for around $160.00, and then installed it myself. Go figure it was just out of warranty. I think my next pressure washer will be one with a professional pump as I was told the one on my husky is only rated for about 40 hours of use.
