I have a pump at cabin it pumps water but won t build up pressure and shut off got this pump 7 years first problem

Normally there is a pressure TANK, used in conjunction with a Booster pump. Do you have one on this system? That's where the pressure is stored. If no pressure, the bladder is either failing or has failed.

Pump has not pressure and will not restart automatically

It may be the back flow check valve. If that valve is bad water will recirculate and never build pressure. If that is OK power it down then power back up. If it does not start then the controller is probably bad.

If I use a small amount of water, the pump starts, but does not build pressure. The pump continues to run and acts if it is air locked or lost prime. If I shut the switch off and let the pressure go and...

Sounds like a well pump with a leaky foot valve. I beleive you are correct in that it air lockes then when you shut it off the water flows back eliminiting the air lock.

What is the maximum water temp my machine can take?

The manufacturers do not recommend more than 120deg inlet temp. Overheating is a comon and serious problem for these high RPM direct drive pumps. Heat builds whenever the trigger gun is not pulled. Some pumps have special "hot pack" kits available, but even that maxs out at 160deg. Most real washers made for hot water, heat the water after the pump, not before. Special separate Hot Boxes are available for 2k or so.

Have an Onga JJ400 jet water pump several years old, pump is working but delivering poor water flow

Is the pump building pressure and shutting off? If the pump keeps running but not building pressure than there is most likely a problem with the well (low volume). Also check for a water logged bladder tank.

Karcher G 3050 OH the pressure is not constant, I think that is the pumps pressure regulator but I'm not sure

Check the suction line for leaks. It needs constant water
supply to build a constant water pressure. You may also
check the pressure regulator for leaks. You may also
check the carbide or ceramic pistons for breaks. Send you e-mail for further assistance.
