« on: April 06, 2016, 02:01:42 pm »
had my was jetwash for a couple weeks, its 3000psi 21lpm

at customers house, start it all up, pull trigger fine, pull trigger again and the bolt at the bottom of the unloader (the bypass bolt/plug) explodes off, threading the unloader and bolt in the process! what the hell happened and what have i dont wrong? lol

spoke to the supplier he says he's never seen that happen before. he says makes sure the adjuster isnt all the way down??? (i cant remember if it was or not) fair enough if its my fault, its my fault, but surely if its as easy as having the adjuster to far down there should be warnings about it??

any input much apreciated!!

cheers

Surely if it's a new washer any reputable supplier worth their salt should sort it out under the warranty not just say it was your fault?

What washer did you get and what was the name of the supplier?

It's also wise once you get into pressure washing to have a backup washer should something happen say halfway through a job . I've accumalated three over a period of time so alway have a spare working washer if need be so can nip back and get one should I not be able to fix it on-site. Same goes for spare pressure washer hoses, lances, flat surface cleaners etc as can save a lot of hassle. Other option is to hire one to get you out of the crapper.

There is  nothing worse than having a breakdown on a job and I've had some to mention a few: pull cord snap, hoses blow, couplings break, lance trigger fails, fsc bearing fail but never had a washer engine break down or pump fail on a job yet touch wood.

the supplier said he'd send me a replacement bolt (a lot of good if the unloader's threaded aswell) I'll give the bolt a go and if it doesn't work I'll be asking for a replacement unloader.

I'm not one for complaining i just draw a line under it and shop elsewhere. I'll see how it goes before I name and shame. Let's just say they had raving reviews! And so far I ain't impressed. I've already purchased a new unloader as I need the jet wash up and running asap. Also bought a pressure release valve, just need to figure out the best place for it.

You dont need a prv and an unloader as they do the same job except one is clever and the other dumb. A prv just dumps excess pressure and the unloader looks for a max to unload then loads back up when the line pressure drops. Flow sensitive are similar to pressure sensitive  with the exception  that they look for flow rather than a drop in pressure.

Your supplier should help you  as you clearly have a blockage or a dodgy unloader. Clean the nozzle and then when washing wind the unloader numpty in until you don't have a flow on the return line - once set you don't need to mess with the unloader again. Should you need a reduced flow drop the revs by watching the rtt for the smaller nozzle - this will also show a worn unloader

thanks for the advice. i'll have 2 of these unloaders now so hopefully i'll be ok! if they keep going ill go for the k series jobby!

i was reading somewhere that you can fit a pressure relief valve aswell as a unloader as a second safety measure? or am i tottaly wrong?

cheers

You can but there really is no need - the machine will stall usually but if it makes you happy then it will be a second safeguard. Tee it into the RTT from the unloader. K series are great in the range but a pain if you do gum, want steam or a small flow.

got onto trading standards about it, the women says i have to give them 1 chance to repair it, so we will see.

i'm really hoping the new head solves the issue becuase i can see this turning into a nightmare. already lost business becuase of this and have looked like a complete mug infront of the same customer TWICE!

last time i try to save a few quid on a jetwash! will drive the hour to the more local place.  >:(

But they are not repairing it you are  ::)roll

Thats like buying a brand new car and the gearbox goes then the dealer expect you to fit the new replacement parts youself. Would you replace the gearbox youself... I don't think so.

tell me about it, spent 3 hours putting the new unloader on today then the  pump starting leaking, i couldnt believe it. he told me to put some ptfe tape on the bolts.... 1000 pound jetwash 3 weeks old...

he sending me the complete head with unloader attached etc so its just a bolt on jobby, so not to bad. if the heads knackered is there anything else inside the pump that can be affected?

Why are they not fixing it for you under the warranty? Can they not arrange to pick it up to either sort it out or give you a full refund?

Name and shame  ;) If you have no real mechanical skills or knowledge how do they expect you to fix it ? I bought a new washer from Wrightway and there was an issue after 2 weeks. I phoned them  and explained and asked if it was OK for me to strip it which I did, sent them the photos and the courier was at my door at 8am the next morning with the part. I am an engineer by trade but you should really be sending the machine back for repair.

i'm fairly good with a spanner so taking stuff apart and putting it back together isnt a problem but your right. ive asked for a refund but he doesnt want to accept the machine is faulty, he's blaming me for the damage. he did ask for me to send the pump to them, but what then? they say its knackered i need to buy another and all this time i cant work!

i dont mind tickering with things and fixing stuff etc, but i purchased a brand new one so i could have a carefree jetwash for a couple years.

i just dot see how me winding down the loader too far would make any difference. for one the lock nuts where 3/4 down so i couldnt even wind it too much. the only way i can see it happening is the unloader getting jammed, so the pressure couldnt go anywhere. i even had the handle pulled as it started.

if it was as simple as having the unloader wound down too far, jetwash's wood be popping all over the place????

ive scoured the web and cant find any other cases like this, where the unloader has popped

dont want to name and shame becuase maybe we can still get this sorted out. but you wouldnt beleive whats been said over the phone today. UNBELIEVABLE, is what my wife said when i had him on loud speaker...

If it was the Irish fella I spoke to him once about a Hatz machine and he said they were crap ! whys he still sell them then. The warranty may be a return to base but he should fix the issue - if the unloader  can be over pressured then there should be a limited adjustment or a proceedure in the user manual.  It does sound like he's blowing smoke up your arse and if it were me the machine would be on a pallet back to him for a refund. Where are you based ?
