Pressure washer
I have a Hozelock Compact Pressure Washer 100. It's about 4 years old and
only gets used once per year to blast the driveway at Pounder Towers. I've forgotten how much it cost, but I don't think it was much. Today I noticed that when the trigger on the gun is released the motor was still running. It should turn off ........ I've RTFM. It's no big deal as I just turn it off on the switch, I don't leave it running when I go for a fag. If I have a look inside, has anybody got any idea of what I should be looking for? I've emailed Hozelock, but I've a good idea of what they are going to say ....... Taa |

Taa The motor is wired through a pressure switch, and switches off - or should do! - when the target pressure is reached. So either the pressure switch has failed closed, or the target pressure isn't being achieved - possibly because of an internal leak. -- Cheers, Roger ____________ Please reply to Newsgroup.

I've emailed Hozelock, but I've a good idea of what they are going to say These pressure washers are positive displacement pumps. So, if it still runs when the outlet vleve is shut, there must be a bypass valve as last ditch pump moter protection. So, either ther pressure switch that should turn it off is faulty. (And bypass valve is lifting) Or The by-pass valve is faulty. Ie Passing water at too low a pressure. Valve seat knackered sort of thing. Pressure switch seems more likely. |

It sounds like the valve. As this thing looks like a pig to take apart and Hozelock seem to have a reputation for not supplying parts, I'll just keep turning off on the switch. Thanks for the heads up. |

I'll leave it be as I could well cock the thing up taking it apart. Cheers Harry. It sounds like the valve.
