Frequently Asked Questions
At PowerWash.com, we prioritize the performance and dependability of the engine and pump over brand names. Our dedication lies in providing our customers with top-notch pressure washers that deliver exceptional results. We understand that brand loyalty can sometimes overshadow the true value and functionality of a product, which is why we meticulously curate our recommendations based on performance, reliability, and overall user experience.
The importance of GPM (flow) vs. PSI (pressure) depends on the cleaning task. Generally, prioritize GPM for larger areas and PSI for stubborn dirt, while considering the surface’s recommended pressure ratings.
Proper nozzle sizing ensures safe and efficient operation, especially when changing the pump’s specifications.
White smoke is usually residual oil burning off and is not harmful. Persistent smoking or black smoke indicates a potential issue that needs further investigation.
To replace the oil plug:
- Unscrew the sealed plug shipped with the washer.
- Replace it with the vented plug provided.
- Clean any oil from parts like the air filter or spark plug if necessary.
Use non-detergent, non-foaming oil for the pump, and refer to the owner’s manual for the correct engine oil, typically SAE 10W-30 or a suitable alternative based on operating temperature.
Change the engine oil after the first 20 hours or 1 month of use, then every 6 months or 100 hours. Change the pump oil after the first 50 hours, then every 100 hours or 3 months.
To winterize your pressure washer:
- Stabilize the fuel.
- Flush out all water.
- Use a pump-saver to protect against freezing and moisture.
Direct-drive pressure washers cannot pull water due to their high RPM, unlike belt-driven models which are designed for gravity-fed water sources.
A hot water pressure washer heats water after it passes through the pump, allowing it to function as a cold water washer as well. The water is heated before reaching the hose and gun.
No, it’s not recommended to repair a leaking hose. Replace it with a new high-pressure hose for safety and efficiency.
Yes, you can connect hoses of varying diameters if:
- The connections are compatible.
- The flow is not restricted, ideally going from smaller to larger diameter hoses.
Yes, always turn off your pressure washer when not in use to:
- Prevent overheating and damage to the pump.
- Avoid melting the pump seals.
Pressure washer surging can be due to:
- Restricted water flow.
- Kinks or blockages in hoses.
- Debris in the nozzle.
To address low pressure issues:
- Ensure hoses are not kinked or blocked.
- Clean the water inlet filter.
- Check and clean the trigger gun and nozzles.
This cycling issue is often caused by:
- Leaks in the system.
- Pressure switch activation due to pressure changes.
- Check for proper connections and intact O-rings.
Your electric pressure washer might stop due to:
- Disconnected power cord.
- Tripped GFCI or circuit breaker.
- Overloaded circuits due to high amperage appliances on the same circuit.
If your electric pressure washer isn’t starting, consider these tips:
- Avoid using extension cords as they can harm your machine.
- Ensure the power cord is plugged directly into a grounded outlet.
- Check for a tripped Ground Fault Circuit Interrupter (GFCI) and reset it according to your owner’s manual.
- Connect the high-pressure hose between the spray wand and the pressure washer.
- Turn on the water supply.
- Press the trigger on the spray wand to release any trapped water or air.
- Keep the trigger pressed and turn the washer to the “ON” position.
