If your pressure washer pump is not performing as it should, don’t be afraid of repairing it.
First off, if it’s not working you can’t make it worse! Right? So don’t worry about that.
Second, most decent pressure washer pumps are made to be repaired. Parts are available and there is usually easy access to the working parts of the pumps. Now, notice I said ‘decent pressure washer pumps’. The cheaper the pump (or pressure washer) the less likely that parts are available or that the pump can even be repaired. Look for brands on the pump [Annovi Reverberi (AR), CAT Pumps, General Pumps], those are easy to find parts for and repair. There are cheap gas powered pumps that are better off being replaced (Devilbiss comes to mind, or any no name pump). Sames goes for electric pumps, but they are even more sketchy at the cheaper prices.
Third, there are only so many things that can go wrong on one of these pumps. They aren’t that complex. So don’t get overwhelmed. It’s not bad.
So much for the inspirational talk. Let’s get to work on those pumps!
This is the first in a series of pressure washer pump repair articles. The first few will be general in nature, then I’ll work on getting more specific in future posts.
When looking at repairing a pressure washer pump, the first thing to do is make sure it’s the pump that’s not working correctly. I know, sounds silly. But it can be easy to guess it’s the pump, because the motor is running fine. So it’s gotta be the pump, right? Maybe.
Sometimes where there is a loss of pressure on a pressure washer, it can be the hose/gun/wand assembly causing the issue. So, the easiest thing to do is remove it all from the pump (not while it’s running). Shut down the washer and disconnect the hose from the pressure washer. Crank it up. Is water shooting out of the pump or just trickling out? Shut it down.
If it’s shooting out, there may be an issue with the hose/gun/wand. Look for kinks or blockages throughout that system.
If it’s trickling out, then you have a pump problem. Sometimes it’s between trickling and shooting out. Well, that’s a pump problem as well.
We will look at diagnosing pump problems in future posts in this series.
