Pressure washer lost pressure in the middle of a job

you have a blockage in the jet at the end of the wand

Hello Morris Daniels - Are the house valves fully turn on? Is the hose kinked or pinched? If not, then it sounds like you have an issue with the water pressure and possibly will need to replace the pressure switch. First try checking water pressure at another faucet in the house. Wait until water supply and pressure increase (water pressure for washer must be at a minimum of 30 psi). Straighten the water inlet hose if it is twisted or kinked. If any proves to be ineffective, contact a professional to move forward accurately.

Hello - Washer not filling with water can be caused by many reasons. Most common cause is a faulty switch that doesn't allow the value inside turn or a kinked fill hose. Other possibilities can be water valve faults, faulty control board, pressure switch or wiring failure. Are the house valves turn on fully? Contact a professional to move forward accurately?

Hello there and welcome to fixya
there are several things that you will need to check first ok please verrify the following
It doesn't pump or spin
If it doesn't pump water out or spin, check to see if the motor is running, then proceed as follows:
If the motor is running, your washer probably has a frozen pump pulley or a broken pump belt. To check the pulley, remove the pump from the washer and try to rotate the pulley manually. If it doesn't turn freely--if it's frozen or stiff--replace it. If the pump belt is broken or looks quite worn, replace it--but be sure to check the pump pulley before you change the belt.
If the motor isn't running, the lid switch may be defective. If so, the washing machine can't spin and may not function at all. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washing machine to get to the switch. If it's defective, you need to replace it.
It pumps, but doesn't spin
If your washer pumps out the water but doesn't spin, check these:
The lid switch may be defective. If it is, the washing machine doesn't spin. The switch is inside the washing machine main housing near the door frame. Often you have to raise or open the top or front of the washing machine to get to the switch. If it's defective, you need to replace it.

Hello there and thank you for choosing fixya

The motor coupler may be broken. Many Whirlpool®-manufactured washers use a small, relatively inexpensive motor coupling. It's plastic and rubber and is mounted to the shaft of the motor on one side, and to the transmission on the other. Over time, the coupler wears out and fails. You may need to replace it.
A belt may be broken. Many washing machines have one or two belts. If a belt is broken or badly worn, you need to replace it with a genuine belt from the manufacturer. (Some washing machine belts are designed with special characteristics not found in automotive belts.)
The clutch may be worn. If your washer is a GE, it may use a clutch to come up to the proper spin speed. As the clutch wears out, it may prevent the unit from spinning well or at all. If the clutch is worn, you need to replace it. For this job, you probably want to hire a qualified appliance repair technician.
The drive motor may be defective. Many washer brands use a reversing motor. For agitation the motor runs in one direction, for spinning and draining, the other. It's possible for a motor to burn out in one direction and continue to operate in the other. If this happens, you need to replace the entire motor.
The transmission may not be shifting properly. Older washers produced by Whirlpool® have a transmission with an electro-mechanical shifter. If the shifter becomes even partially defective, the unit may drain the water but not spin. This is a complex system, if your washer has a shifter problem, you may want to hire a qualified appliance repair technician to repair it.
The spin bearing or basket drive may be worn or seized. These components allow the inner tub to spin freely inside the outer tub. When this is the problem, you usually hear a loud sound during the spin cycle. Call a qualified appliance repair technician.

what you need is a pressure pliers tool , that will do the job, thanks AJ

You only have to regulate the incoming valve in your wall (to the washer) to have safe pressure.........don't see any reason why you can't do this.........& get on with your tons.......
