The pressure hose fitting (AR114 power washer) refuses to stay in the unit.

if you're talking about the high pressure hose, no it does not it connects to the machine and then to the host using a quick disconnect

There are several different configurations for these fittings. If you bought a generic replacement hose, it may have a different fitting than what is on the machine. May have to replace the fitting on the machine, or buy a hose specific to your pressure washer.

If you are replacing the hose because it burst you might contact the manufacturer. Mine, of a different brand, burst and they sent me a new pressure washer saying that it was very difficult to install a new hose. They had a lot of problems with hoses from China.

I just finished replacing mine.

It is much easier if you do these steps:

1. Remove the serpentine belt.
2. Remove the nuts holding the main fuse box over the battery.
3. Remove the reinforcing bar over the battery.
4. Remove the battery.
5. Remove the windsheild washer tank.
6. Now you have access to remove the pump pulley. Without removing the stuff, it may be possible, but it will be extremely difficult.
7. Remove the pump pulley.
8. Loosen the high pressure hose fitting.
9. Remove the return line clamp.
10. Remove the power steering pump mounting bolts.
11. Remove the high pressure hose fitting.
12. Remove the power steering pump while sliding off the low pressure hose.
13. Remove the clips holding the reservoir on the pump.
14. Remove the reservoir.
15. Install new o-ring on the reservoir.
16. Install reservoir on new pump.
17. Install clips to hold reservoir on pump.
18. Install new o-ring on high pressure fitting.
19. Place new pump in position while sliding on low pressure hose.
20. Loosely attache high pressure fitting.
21. Tighten pump to mounts.
22. Tighten high pressure fitting.
23. Install clamp on low pressure hose.
24. Install power steering pulley.
25. Install washer reservoir.
26. Install battery.
27. Install reinforcing cross member.
28. Install fuse panel.
29. Install serpentine belt.
30. Bleed the power steering system.

need to remove front panel on washer usually 2 clips at top of unit between front panel and top panel approx 2 inches over and one on each side..if you stick a slim screwdriver in you can gently push and the clips will release allowing you to remove front cover.. once in there check the side of tub there is a small hose runs to side of tub assembly this is a pressure switch hose make sure it is connected and no holes in it.. if that is ok then check hoses going to tub and at the drain pump assembly.. may require you to start washer to check connections ... if no obvious leaks yet then fill washer and run through a spin cycle check pump assembly they are notorious for cracking or leaking ... hopefully you can find culprit this way... once you find source of water you can order parts from www.sears.com then hit the parts direct link up top it will go to a page you can enter your model number and find a parts diagram and price ...good luck to you

I have a SIMONIZ S2000 electric. I bought the unit about 8 weeks ago used it once. On the second use yesterday the unit didn't work as well, the pressure seemed only a bit better than hose pressure and soap did not dispense at any pressure. SO.... after much thought I turned the hose/tap pressure down so that I only got about 2-3 GPM instead of the typical 5-6GPM normally coming out of my hose....... it worked! Soap dispenses and spay is way better! It seems that if if the inlet hose pressure is high the pump doesn't work as well... go figure.

1. If you have an inlet chemical injection valve make sure that the hose is intact and that the valve is closed.
2. Purge all air from the line by holding the nozzle actuation lever open until all air has been purged. When you connect the water supply hose turn it on before connecting the high pressure hose and let the unit self purge to the pump outlet high pressure hose fitting. Then connect the high pressure hose.
3. You could have a stuck spring and ball inside the high pressure head of the pump. You can tip the unit on its' side and add a substantial amount of WD-40 to the water supply hose fitting in an attempt to free the springs and balls.
4. Try BRIEFLY running the unit without the hose connected to see if there is high pressure water ejected from the high pressure fitting.
5. Inlet water screen at hose connection is clogged (hose screen and rubber) Check screen for debris.
6. The water strainer is clogged. (Almost looks like an LPG regulator just after but in line of the supply hose connection to the pump)

Order of troubleshooting

1, 2, 5, 6, 4, then 3.

Thanks for using FixYa!

with unit unpluged,turn water on,if water come's in you have a bad inlet valve,if not than check rubber hose from outer tube to water level switch,if thy are connected than you have a bad water leaval switch.

there is a small clip on the triger where the hose attaches to is, pull clip out pull hose off
