If the pressure washer engine doesn`t spin as you pull out the recoil starter rope, you probably need to replace the recoil starter, because it`s not spinning the flywheel. If the starter rope won`t budge when you try to pull it, the engine may be locked up or the recoil starter may have failed.
If your pressure washer is refusing to work or even turn on, the culprit could potentially be the power switches. Most pressure washers use two micro switches that disconnect both the live and neutral connections between the supply and the motor. These switches can jam cutting the power out from reaching the motor.
If the pump is leaking, the cause may be minor and easy to repair. Check the seals, packings, and O-rings for wear. These can easily be replaced, saving you the cost of a new pump. However, major leaks such as the ones caused by cracked or damaged plungers, can lead to pump failures.
It Can Harm The Unit

A pressure washer requires water to cool and lubricate the pump, which is the part responsible for pushing water from the supply hose to the nozzle. Without water to cool and lubricate it, the pump will work harder than it should, causing it to wear down quickly.

In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
Water leaks and inconsistent behavior are also signs of a potential failure in the near future. González: The typical signal when there is an unloader malfunction is a reduction of flow through the nozzle, which results in pressure loss. Dean: Typical symptom of an unloader failure is a sudden smooth pressure loss.
In simple terms, the mathematical constant 2.31 converts a unit of energy against gravity into a unit of force against any other area. This constant converts a foot of head of water into pressure: Head in feet of water divided by 2.31 equals pressure in psi, and pressure in psi times 2.31 equals head in feet.
By definition, `Head` is a measure of energy. The units of energy are feet (or meters). `Pressure` is a force applied against a unit of area such as a pound of force applied to a square inch of area (psi).

I have used the McCulloch (FH180A) three times over the course of two years. On my fourth use the pressure washer just surged on and off and I would get a tiny spray from the gun each time it surged. In other words it would do nothing. Please help… very frustrated. Thanks
ANSWER : Sounds like the problem could be low input water flow or pressure. There could be crud on the intake where you hook up the garden hose, there could be some other sort of blockage. Try hooking it up to the hose and pull the trigger (with the power switched off) and wait to see if water comes out the tip. Also look at the tip(s) themselves. sometimes a piece of crud gets into the hose and then clogs the tip.
