Why want my pressure washer suction the solution while pressure washing the house?

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.

Dismount the bolt that is use to connect the soap line.Turn on the washer and test if you fill if is "suction" intake air.Sometimes it becomes clogged so see if anything is clogging the suction .Is that not work the suction system is bad.

Possible that the waterlevel sensor pressure switch is not working and so unless it contacts the cycle will not proceed according to the program.
So remove and test the pressure switch with a suction or blowing to see the contacts clicking.
If the switch is OK the program controller can be faulty

there should be a low presure tip for dispensing wash cleaner or if you have an adjustable wand turn it to low presure setting also make sure the suction tube is open some have a adjustable filter...good luck

your not missing anything, check the pump, they tend to go bad over time and may need replacing. The pump provides the pressure as well as the suction for the whole process, pulling water from the hose or tank and pushing it forcefully through the pressure washer line. If the motor is running and you have the water going through the line and to the pump, and no water is coming out, my guess would be the pump.

Since you did not mention the pump brand or type. I will just assume it to be a pressure washer, complete
with gun. The pump comes two suction hoses. One for the water supply and one for the soap bottle or pail There is pressure adjuster right at the pump near where the hose is connected. You can adjust to higher pressure by turning it clockwise. You can adjust the nozzle spray pattern by turning it. However, if your pump comes with only one set of suction hose. Then, it is designed to get the water
supply from the faucet with hose bib. The only one
set of hose is for the soap bottle or pail. It will **** the soap once the nozzle spray is opened.
hose,

Picks up under low pressure conditions by adjusting wand or changing tip.

your filter is dead. fit new cyclone filter

inlet valve connected to water inlet is stopped-up. Unscrew it, take a safety pin run through valve then take the pin and push through valve connected to pump. should do the trick. (the valve the suction hose for the soap is connect to)

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.......
