Question about McCulloch FHH25A Gas Pressure Washer
Posted by Anonymous on
Sound like you need to replace the unloader valve,or take it apart and free it up,lube the seats and o rings and retry the washer to see if it works.The valve has the pressure regulator in it so the knob that you adjust the pressure with needs to come off and then just unscrew the unloader valve.

1) Make sure there is water in the solution tank.
2) Try priming the machine by instructing the consumer to squeeze the trigger
repeatedly for 1 to 2 full minutes. Important: If you cannot
squeeze the trigger all the way in, remove the tank from the back of the
machine and then try squeezing the trigger with the tank removed. There is an
internal valve that could be sticking. By removing the solution tank and squeezing
the trigger, it should break it loose, allowing the trigger to be fully depressed.
3) Make sure the open end of the siphon tube in the solution tank is not pushed into the
side of the tank, covering the end of tube. If it is, push the bend in the
Siphon tube toward the back of the solution tank.
4) Check to see if the siphon tube has become disconnected from the outlet fitting on
the inside of the solution tank. If so, you need to buy a replacement solution tank. Parts
can be found at www.bissell.com
5) Check to see if air comes through the spray tip by repeatedly squeezing the trigger
with solution tank off the unit. If not, spray tip may be clogged. Try and unclog
spray tip with a pin or paper clip.
If still no spray, please check the following:
a) Make sure the solution tank is installed properly.
b) Check to see if black O-ring is present on rear connector to solution tank.
