Pressure washers by Excell are an excellent cleaning alternative for all domestic and professional applications. Some of the most common issues with pressure washers occur with their pump and the water supply network of hoses. Typical problems are water pressure being too little or too high, the water leaking from either the pump or the hoses, or the pump making strange noises.
Excell Pressure Washer Problems:
If your Excell pressure washer is leaking water, locate the leak source, which could be either the pump, the input hose, the high-pressure hose, or the spray gun. Ensure that all the seals and connectors are tight and intact. In case of pressure fluctuations, examine the nozzles and make sure the unloader valve is correctly calibrated. If the pump makes strange noises or leaks oil, check it’s properly lubricated and inspect its seals to see if they aren’t damaged.

Excell Pressure Washer is Leaking Water
Water could escape from your Excell pressure washer’s hose attachments. To determine the water leak’s location, inspect the pump’s hose connections and spray gun one by one.
One of these three sites is more likely to develop a leak. The pump itself might cause the leak. Another possible leak location can be the pump’s intake and exit hose connections. Furthermore, water could also escape from the spray gun’s connection with the high-pressure hose.
● Excell Pressure Washer: Water Leaking from the Pump
If your Excell pressure washer leaks water straight from the pump, the piston seals are most likely worn out and need to be replaced.
Most pressure washer pumps use a positive displacement piston mechanism to push water across the hoses. A piston seal keeps water from entering the pump. These seals deteriorate with time, eventually leading to a leak. In such a scenario, you may need to remove the pump casing and inspect the piston seals by yourself for indications of wear.
This only applies if you have a plunger pump. Axial and wobbling plate pumps are factory built and cannot be dismantled for repairs. Consequently, their seals cannot be changed separately, and the whole pump must be replaced to resolve the problem.
● Excell Pressure Washer: Water Leaking from the Hose Connection
If the hose connections on your pressure washer are leaking, you should try replacing the pipe fittings/couplings at these attachments.
A pipe connector attaches the pipe to the low-pressure inlet of the pump, and the seal on these connections is leak-proof. As a result, if there is a leak at this site, it is more probable that the connection and its seal have worn out. Similarly, the outlet seal should be replaced if the connection at the pump’s high-pressure output and its accompanying hose leaks.
● Excell Pressure Washer: Water Leaking from the Spray Gun
Examine the hose-gun connection and tighten the screws if the spray gun on your Excell pressure washer leaks. In addition, check the high-pressure line at the outlet for a damaged O-ring and replace it if necessary.
Most pressure washers use a push fit to connect the high-pressure hose to the spray cannon. Check that the fit is proper and that the connection is not loose. If it contains screws, make sure they’re tight. If the leak persists after tightening the fitting, check to see if the hose’s O-ring is present and undamaged. This leak might have been caused by a broken or missing O-ring.
Pressure washer seals, gaskets, and O-rings are available at various local stores and online.
Excell Pressure Washer: Water Pressure Problems
Follow the steps below if your Excell pressure washer isn’t creating sufficient water pressure.
● 1. Excell Pressure Washer: Low Pressure
To resolve low water pressure, check that enough water is entering the system and that the input line is not blocked with debris. Additionally, ensure that the exit nozzle is not worn out or clogged.
The volume of water entering the pump must be sufficient to create sufficient pressure to perform the cleaning. You must also examine and eliminate any twists or bends in the inlet hose. Furthermore, most inlet hoses have a dust filter that connects to the pump. Check and see if any dust has been lodged in the filter. If the pressure remains low, ensure you’re using the correct nozzle, and it’s not clogged with debris.
● 2. Excell Pressure Washer: No Pressure
Check the water source, hoses, and nozzle if your pressure washer loses pressure. After that, examine the unloader valve and the pump; at least one must be repaired.
Pressure loss may also be caused by nozzle debris or a low water supply. The problem is most likely with the pump and unloader valve in this scenario. Adjust the unloader valve gently while the pump operates, and the trigger is pressed to check whether the pressure improves.
If the issue continues, the unloader valve, which could be faulty, must be replaced. It would be good if you also examined the plungers and O-rings of your pump for damage.
Air bubbles caused by cavitation may cause long-term damage to different pump components, resulting in pressure loss. Before changing the components of your pump, consult the owner’s manual. Because most pumps are manufactured as a whole unit, they cannot be dismantled and must be entirely replaced with an identical one.
● 3. Excell Pressure Washer: Surging Pressure
Inspect your nozzle for clogs or signs of damage if your water pressure suddenly increases. Adjust the unloader valve so more water enters the bypass and less reaches the spray nozzle.
A pressure washer’s unloader valve transfers a part of the high-pressure water flow to the pump intake or water tank rather than the spray nozzle. Very little incoming flow is bypassed when you tighten the unloader valve, resulting in high pressure at the nozzle output.
Loosening the unloader valve increases the bypass flow rate, minimizing pressure spikes at the spray gun. If this does not work, examine your nozzle for apparent signs of damage and replace it as the manufacturer directs.
● 4. Excell Pressure Washer: Drops Pressure after a Few Seconds
If your water pressure drops abruptly, it might be due to a worn-out nozzle or a hose leak. A faulty unloader valve might potentially have contributed to this problem.
In contrast to the earlier example of surging, if the unloader is adjusted too loosely, the pressure at the spray gun may decrease. If this setting is too loose, any flow quantity may overcome the spring tension and flow to the water tank. As an outcome, the water pressure at the nozzle exit drops. Furthermore, check your hoses for any holes or leaks. Make sure your nozzle is not clogged with dirt or debris.
● 5. Excell Pressure Washer: Strange Noises from Pump
If your pump is producing strange noises, it might be due to worn-out connecting rods or bearings. Lack of timely lubrication of the pump also results in the generation of unwanted noise.
High-end pressure washers’ plunger-type pumps need oil replenishment every three months. Consequently, frequent maintenance is required for these pumps to work efficiently. The pump in low-end variants is either axial or wobbling plate type. These pumps do not need oil refill since they are permanently sealed with oil after manufacturing.
– Simple fix
The pump should be serviced and greased every three months, depending on the pressure washer (axial or plunger). Non-greased metal components tend to rub against each other, generating a lot of noise. If this happens, remove the plunger pump and examine the bearings and connecting rods. A bearing replacement may be required if lubricating the pump does not resolve the issue.
If the noise continues, the pump’s connecting rods may be defective, mainly if your pump is old. Fatigue and tension may hasten the wear rate of your pump’s connecting rods, particularly if it has been operating for an extended period.
If your pressure washer’s axial or wobbling plate pump makes weird sounds, replace it with an identical pump since it cannot be repaired.
● 6. Excell Pressure Washer: Excessive Noise
If your pressure washer is making a lot of noise, it might be due to damaged internal pump components, the air seeping into the pump, a cracked pump casing, or sounds of the engine knocking due to bad fuel.
– Pump Wear and Tear:
Vibrations and noise may develop if the pump’s casing is broken. In addition, a loud grinding noise may also be caused when air bubbles get entrapped in the pump. This can wear down the seals and connecting rods of the pump.
– Engine Knocking:
Check the fuel quality in your gas-powered pressure washer engine if it is rattling. To eliminate engine knocking, I recommend using ethanol-free, unleaded gasoline with an octane number of at least 87. You can also look in your owner’s manual for more information.
● 7. Excell Pressure Washer: Oil Leaking from the Pump
A cracked O-ring or a damaged seal causes oil to escape from a pump. If required, dismantle your pump and replace all the seals by hand. If the product is still under warranty, contact the manufacturer for help.
Even though your pump’s warranty has expired, it may still be fixed if you disassemble it. You can hire a mechanic or contact the manufacturer if you lack the requisite expertise. To help you with the replacements, I suggest purchasing an oil seal kit comprising seals and rings in different sizes.
During reassembly, be sure that all bolts and fittings are correctly tightened. Pressure washers should never be exposed to high temperatures to avoid further oil leaks. If your pressure washer’s pump is permanently sealed, the only solution is to replace it.
● 8. Excell Pressure Washer: Water in Oil
Water may enter the pressure washer if the oil seal on the pump gets broken. You should consider replacing the seal in this situation.
Water causes the pump oil to become milky, further confirmed by a damaged oil seal. The pump must be completely disassembled to replace the seal, including the housing, valves, seals, and rings.
I’d do this right after the pump’s warranty expires. If the pump is still under warranty, the manufacturer should repair or replace it. This only applies to pressure washers, such as plunger pumps, whose pump oil can be replaced. Most low-cost pressure washer pumps are permanently sealed and must be entirely replaced if broken.
● 9. Excell Pressure Washer: Soap Not Dispensing from Reservoir
If your pressure washer isn’t siphoning soap from the reservoir, you should check if you are using the right-sized nozzle. In addition, you should examine the soap injector kit and see if any parts are damaged or worn out.
The owner’s manual recommends a specific nozzle for the soap injection function, which provides sufficient suction pressure for all detergent types. Make sure you’re using the proper nozzle. If it still doesn’t work, ensure the nozzle on your injection kit isn’t clogged. A chemical injector repair kit may help you by supplying the necessary replacement parts.
