Clogged Intake Filter

The intake filter plays a decent role in keeping your water pump safe from any additional dirt and debris. So, if the intake filter is full of dirt and debris, it restricts the flow of water inside the fuel pump, and thus, the issue of inadequate pressure from the pressure washer occurs.

What should you do to fix the clogged intake filter? 

The solution to this problem is simple. You neither need to call a mechanic nor spend too much money. Instead, you should carefully remove the intake filter and inspect its condition.

Now hang on. If you find debris on the intake filter, rinse it under a water tap. Doing so will help you remove the debris from the intake filter. Beyond that, try to clean the intake filter regularly.

In addition to that, check the link below to understand the issue of a clogged intake filter on your Ryobi pressure washer.

Blocked Nozzle

This is one of the most frequent issues with the Ryobi pressure washer. Similar to the intake filter, the debris can also run into the jet of the pressure washer’s nozzle.

Unfortunately, you won’t get the expected water pressure from your Ryobi pressure washer if this happens.

OK, I know what you’re thinking. Well, recovering the issue of blocked nozzles can be pretty straightforward too. You need a handy teeny tiny tool that looks like a pin. You are supposed to have one in your brand-new Ryobi pressure washer.

In most cases, the tool comes with the user manual of the Ryobi pressure washer.

Now, want to see how it works right now?

You need to remove the nozzle from the spraying gun on your pressure washer. Next, you should hold the nozzle in your hand, and, on the other hand, you need to poke the cleaning kit inside the jet of the nozzle.

Next, move the cleaning kit around to clear away the debris that might be stuck inside the jet under the nozzle. Do this a couple of times. Once you have done this, clean the nozzle with fresh water.

Note: Keep the cleaning kit in the right place so you can use it later. Follow the video below from the Ryobi official YouTube channel about cleaning the blocked nozzle.

Insufficient Water Supply

How can you ever expect decent water pressure from your Ryobi pressure washer if there is an insufficient water supply?

Extreme changes are due to inadequate water supply in different sections of the pressure washers causing improper pressure. So, you need to fix the issues as soon as you can.

But here’s a catch. You may be wondering where you need to start. Or, what to check first? Check the steps below.

• Step 1: Check the garden hose connected to the garden tap. If the hose is not properly tightened or connected, you should try to connect it properly with the garden tap.
• Step 2: Inspect whether there is any leakage in the house of the pressure washer. If you find any leakage, you should repair it or replace the hoses based on their condition.
• Step 3: Notice whether any part of the hose is kinked. You should straighten the hose if you find the issue of hose kinking.
• Step 4: Check the pressure hose if it is wounded. If you find the problem, ensure the pressure hose is fully unwounded. This will help the hose to ensure a smoother supply of water through it.

Faulty Water Pump

The water pump, one of the main components of a pressure washer, may be defective over the years. However, there’s no rule of thumb that you only need to replace it if there is additional damage. Beyond that, you should replace it if it gets too much older.

• Step 3: Once you remove the bolts, you should pull out the pump using your hands.
• Step 4: Remove the soap hose of the pump.
• Step 5: Remove the idler assembly using the wrench.
• Step 6: Transfer the thermal relief from the old pump to the new pump. You should also need to use the bolt wrench here.
• Step 7: Install the thermal relief on the new pump.
• Step 8: Tighten the thermal relief after placing it on the new pump.
• Step 9: Insert the idler assembly and soap hose into the new pump.

Air Bubble in the Inlet

We can’t just let this issue unchecked. Too many air bubbles in the inlet cause the issue of the pressure washer, not building pressure. But how do you ensure the problem?

When you press the spray gun, air bubbles are in the inlet if the air from the nozzle is way more than the water. And you need to resolve the issue.

The solution to this problem is simple too. Moreover, the problem occurs if you can’t attach the inlet firmly with the tap. Due to this, air runs into the inlet or hose more than water and affects the performance of the Ryobi pressure washer.

So, to avoid the issue, you need to ensure the inlet of the pressure washer’s hose is firmly connected to the water tap. Moreover, The solution to this problem is more like what you need to do in case of insufficient water supply mentioned above.

Wand Leakage

The wand leakage most probably occurs due to the damage of a defective O-ring. So, to resolve the issues, you need to first fix the O-ring inside the wand of your Ryobi pressure washer. Once you find it is damaged, this is probably the issue that causes wand leakage.

So, the next step is to replace the 0-ring with a new one.

Besides, wand dropping out from hands can cause damage which turns into leakage. So, in this case, you should replace the whole pressure washer wand. However, you can check other common reasons that can make the Ryobi pressure washer wand leaking.
