Your pressure washer provides you the power to blast away dirt, discolorations, and grime from all type of surface areas. If your pressure washer isn’t doing the job — perhaps the engine won’t begin, or it’s not spraying correctly — we have the repairing recommendations to help you identify the issue.
Craftsman Pressure Washer Won’t Start
The part(s) or condition(s) noted below for the sign Pressure washer won’t start are purchased from probably to least most likely to take place. Check or test each product, beginning with the items at the top of the page.
The main Of Frequent Causes for Pressure washer won’t start:
Check the spark plug for signs of wear or damage. If the porcelain insulator is broken, an electrode is burned away or damaged, or there is heavy carbon buildup at the electrode, change the stimulate plug. To identify if the trigger plug is defective, use a stimulate plug tester. You ought to see a strong stimulate in between the tester’s terminals when the engine is cranking. If there is no stimulate, this suggests that the stimulate plug is defective and should be replaced.
The carburetor may be obstructed. A blocked carburetor is most typically triggered by leaving fuel in the pressure washer for an extended period. In time, a few of the ingredients in the fuel might vaporize, leaving behind a thicker, stickier compound. This sticky fuel can clog up the carburetor and prevent the engine from starting. If the carburetor is clogged, attempt cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the whole carburetor.
The ignition coil sends out voltage to the stimulate plug while the engine is running. If the ignition coil is faulty, the engine may not begin. Before replacing the ignition coil, make sure that the spark plug is working correctly. If you have validated that the stimulate plug is working properly, test the ignition coil with an ignition coil tester. If the ignition coil is defective, change it.
The flywheel key may have sheared in half. The flywheel key is a little metal piece which fits into the crankshaft and engages with the flywheel. If the engine stops all of a sudden due to the pressure washer hitting a problematic item, the flywheel key breaks in half to avoid damage to the engine. To identify if the flywheel key is broken, remove the flywheel from the engine and inspect the flywheel key. If the flywheel key is broken, change it.
Craftsman Pressure Washer Runs Rough
Many Frequent Causes for Pressure washer runs rough.
Carburetor – see description above.
Carburetor Repair Kit
The carburetor may be clogged. A clogged up carburetor is most commonly triggered by leaving fuel in the pressure washer for an extended period. In time, some of the components in the fuel might evaporate, leaving behind a thicker, stickier compound. This sticky fuel can clog up the carburetor and cause the engine to run approximately. If the carburetor is obstructed, attempt cleaning it with carburetor cleaner. If cleaning up the carburetor isn’t effective, rebuild or change the entire carburetor.
The fuel filter may be clogged. A blocked fuel filter is most frequently caused by leaving fuel in the pressure washer for a long period. In time, a few of the active ingredients in the fuel might evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the fuel filter and trigger the engine to run roughly. If old fuel was left in the pressure washer, drain pipes the old fuel from the fuel tank and replace the fuel filter.
As fuel is taken in, the pressure in the gas tank rises. To relieve this pressure, the gas cap utilizes a small vent to permit air to get in the gas tank. If the gas cap vent is clogged, air will not have the ability to go into the gas tank, and the pressure in the tank will start to rise. When the pressure in the gas tank exceeds the pressure in the engine, the engine will stall or run inadequately. To identify if the gas cap vent is obstructed, try a little loosening the gas cap and after that beginning the engine. If the loosening up the gas cap allows the engine to remain running, this shows that the gas cap vent is blocked. If the gas cap vent is blocked, replace the gas cap.
The air filter may be blocked. If the air filter is blocked, the engine will get too much fuel and inadequate air. As an outcome, the engine might run approximately. If the air filter is clogged, replace it.
The pre-cleaner might be clogged. However, this is uncommon.
The trigger arrestor is a little screen that avoids the engine from producing triggers. Gradually, the trigger arrestor can become clogged with soot. If the spark arrestor is blocked, the engine might run approximately. To unblock the trigger arrestor, eliminate it and tidy it with a wire brush. You may likewise replace the stimulate arrestor.
Craftsman Pressure Washer Leaking Water
Causes for Pressure washer leaking water:
You might need to reconstruct or change the pump assembly. If the pump is more than a couple of years of ages, and you use the pressure washer reasonably often, change the pump assembly. If the pump is reasonably new, and you do not use the pressure washer frequently, either reconstruct the pump assembly or change the pump seals.
You might require to restore or replace the pump. If the pump is more than a couple of years of ages, and you utilize the pressure washer reasonably typically, change the pump. If the pump is relatively new, and you don’t utilize the pressure washer often, either reconstruct the pump or change the pump seals.
Thermal Release Valve
The leak might be due to the normal operation of the thermal release valve. The thermal release valve permits warm water to leave the pressure washer if the water temperature becomes exceedingly high. If the pressure washer is left running while it is not spraying water, the water in the pump will begin to warm up. When the water temperature rises above the acceptable limitation, the thermal release valve opens to allow the warm water to exit the pressure washer.
