Symptoms of a Pressure Washer Water Pump Not Working
There are a few different symptoms that can indicate that your pressure washer water pump is not working properly. These include:
No water coming out of the spray nozzle:
This is the most obvious sign that something is wrong with your pressure washer. If you turn on the machine and no water comes out, it’s likely that the water pump is not working.
Low water pressure:
Even if water is coming out of the spray nozzle, it may be coming out at a much lower pressure than usual. This can be caused by a number of different problems, including a clogged filter, a faulty water pump, or a problem with the hose.
Loud noises coming from the water pump:
If you hear strange noises coming from your pressure washer’s water pump, it could be a sign that there’s a problem with the pump. These noises could be caused by a number of different things, such as a worn-out impeller, a loose belt, or a problem with the bearings.
The pressure washer won’t start:
If you turn on your pressure washer and it doesn’t start, it could be a sign that there’s a problem with the water pump. This could be caused by a number of different things, such as a blown fuse, a faulty starter, or a problem with the electrical system.
How to Troubleshoot a Pressure Washer Water Pump
If you’re experiencing any of the symptoms listed above, it’s important to troubleshoot the problem and fix it as soon as possible. Here are a few steps you can take to troubleshoot a pressure washer water pump:
1. Check the water supply:
Make sure that there is water flowing to the pressure washer. If there is no water coming out of the faucet, the problem is not with the pressure washer.
2. Check the filter:
The filter on your pressure washer can become clogged with dirt and debris, which can restrict water flow and reduce pressure. Remove the filter and clean it with a brush or under running water.3. Check the hose:
The hose on your pressure washer can also become kinked or damaged, which can restrict water flow. Inspect the hose for any kinks or damage and replace it if necessary.
4. Check the pump:
If you’ve checked the water supply, filter, and hose and the problem persists, it’s likely that the problem is with the pump itself. There are a few things you can check to troubleshoot the pump:
Check the belt:
The belt on your pressure washer’s water pump can become loose or worn out, which can cause the pump to not work properly. Inspect the belt and replace it if necessary.
Check the impeller:
The impeller is a spinning part inside the pump that moves water through the pump. If the impeller is worn out or damaged, it can cause the pump to not work properly. Remove the impeller and inspect it for any damage. Replace the impeller if necessary.
Check the bearings:
The bearings in your pressure washer’s water pump help to keep the pump running smoothly. If the bearings are worn out or damaged, they can cause the pump to make noise and not work properly. Remove the pump and inspect the bearings. Replace the bearings if necessary.
