If you’ve just replaced the unloader valve start with the stupid stuff like is the adjuster screwed all the way closed? I’m assuming it has one. Post a pic or details of the model you have.Hi all. I haveing problems with my Hyundai pressure washer. Anyone know why I’d be getting low pressure?
Just had to replace unloader valve but pressure not what it should be.
Csnt see a problem with water supply or air getting in.
Any other things I can check
Ye I e adjusted unloader valve.If you’ve just replaced the unloader valve start with the stupid stuff like is the adjuster screwed all the way closed? I’m assuming it has one. Post a pic or details of the model you have.
I know on my Jetmac on a couple of occasions I’ve had to back flush the water as it didn’t want to self-prime, giving those symptoms.
I replaced unloader as it exploded off the pump and was lost. I think it’s in orbit as I couldn’t find it anywhere ?Assuming the pump is good id try to back flush it in case it’s not priming.
Out of interest. Why did you replace the unloader. Is it possible it was fine and the issue was somewhere else?
Apart from the back-flush this is above my pay-grade then I’m afraid. Any idea why it ‘exploded’. Fault or just not secured properly? Might have to get this to a repair centre if you can.I replaced unloader as it exploded off the pump and was lost. I think it’s in orbit as I couldn’t find it anywhere ?
I fixed it yesterday. Replaced unloader and the washer then tightened everything up.Apart from the back-flush this is above my pay-grade then I’m afraid. Any idea why it ‘exploded’. Fault or just not secured properly? Might have to get this to a repair centre if you can.
Invariably something simple. Glad you got it sorted. ?.I fixed it yesterday. Replaced unloader and the washer then tightened everything up.
Think it was suckin air in through lose hose attachment. Back to full pressure now.
Thanks for ur help though
They can unscrew themselvesApart from the back-flush this is above my pay-grade then I’m afraid. Any idea why it ‘exploded’. Fault or just not secured properly? Might have to get this to a repair centre if you can.
As in through vibration like any fixing you mean? Or are they inherently more likely for some reason?They can unscrew themselves
They can unscrew themselves through vibration I had it happen on an old Honda one years ago shot off into the bushes never to be seen again ??As in through vibration like any fixing you mean? Or are they inherently more likely for some reason?
