A motor will always try to pull its rated watts. Watts is Voltage x amps. As you have an extension lead, the voltage reaching the pressure washer will be lower due to voltage drop in the cable. So for the motor to deliver the same power (watts) it will naturally pull more amps, blowing the fuse.In fairness, I’ve ran it off an extension lead the past three weeks, before that I was using an outdoor socket. I just started washing the cars further away so I’ll maybe go back to where I was.
My AVA P80 had went 2.5 years without blowing a fuse and now it’s blew three in two weeks.
Anyone have a link for the best fuses to replace them with?
I’ve never seen that happen before mate.Anyone else had this happen?
Puro screw top rips off when tightening it?
Twice now, happened my last one too,
Just means I’ve no seal on top of it now

it can sometimes happen - it did do it with a factory hose from AVA once on me.I got a new rubber hose made up from supplier I heard about on this forum, maybe 2 or 3 years ago and it just keeps bursting. Had it fixed 3 times already and 10 minutes into recent job it bursts again. It's like it is faulty inside and just keeps bursting out.
Supplier tell me it's just one of those things, says I've caught it on some grit and makes a hole (which I find hard to believe), but I'm only using it on Nilfisk 145, maybe once a month just around the house, concrete yard, deck, car, etc.
So I'm convinced it's a bad hose and fed up spending £12 + petrol everytime. I'm going to try somewhere else for a new hose. Any advice on what to ask for? Are there different specs or qualities?
I bought a 10m extension hose from Cleantec in 2019 and it is still like new.

Does anyone know if it's possible to run a powerwasher off a petrol generator? I've an area of kerbing to clean that is a bit away from the electric supply (but has water). I have an old Honda petrol generator that has a 240v outlet on it. If not suitable I'll fit an outside socket instead. Not sure what output the generator has.
I bought the hose from Cleantec, so not that impressed to be honest. Lots of good reviews, good enough service, pleasant staff but definitely something bad about this hose.I bought a 10m extension hose from Cleantec in 2019 and it is still like new. Well worth the money.
There's a hose place I go to that can repair them but last time the burst was at the Nilfisk lance connector and they didn't do that kind of fitting.it can sometimes happen - it did do it with a factory hose from AVA once on me.
I got my local hydraulic hose company to cut the ends off, and make me a new 15m hose and touch wood ive had no further problems with it.
My advice - look for another company closer to you who works with hydraulic hoses.

That’s a simplistic view, power factor is used in the power rating, but it’s just to explain the volt / amp relationship. Lower the volts , a motor will require more amps.
There is always voltage drop across a cable, so always run the heaviest and shortest extension cable you can. And unwind it fully when using high powered items
Depends on your “sparks” background.If it’s installation work, then they will probably never have done any motor theory. They probably think along the lines of “a lightbulb dims as the voltage lowers, so a motor must just spin slower” Sounds logical enough. But, an AC motors speed is governed by the frequency, hence the motor is still trying* to drive at the same speed, but with the lower voltage will pull more current, or worse stall and overheat the windings.God I'm glad someone else on the planet gets that. I've tried to explain the same to a qualified spark in work and they still argued I was wrong.

With a longer cable, the voltage will drop, but the frequency “50hz” will stay the same.
Again, a fairly simplistic description, but explains the basics.
What's the pressure rating of the hose? Grit outside shouldn't make too much of a difference. High pressure hoses are usually are made of at least 3-4 different materials layered up.I got a new rubber hose made up from supplier I heard about on this forum, maybe 2 or 3 years ago and it just keeps bursting.

I don't know the pressure rating and there's no printing on the hose, but I guessed buying it from Cleantec for a simple domestic machine it would be up to the job.What's the pressure rating of the hose?

Love my Ava when it works but their build quality lets them down. That’s the 2nd lance failure I’ve had and then the trigger just decides to fail as well lol
Their warranty doesn’t cover accessories it seems too for more than 2 years so I had to order replacement parts for the trigger and the lance as it was replaced it should be free but they charge a clean stroke for postage as the trigger was a small part and they charge 12 quid for postage
Not sure if I could go back in time I’d buy an AVA again
And I’m storing these in my heated garage so not at risk of frost etc which is what AVA seems to blame it on in their website and replaced all serviceable O rings too
I had something similar this week with my extendable lance.
There's metal tube on the inside for the water to pass through. It has a recess that allows the plastic housing to clamp it in place to stop it coming free when extending the lance. Mine had managed to come free and the water was leaking out of the lance housing like yours. Cleaned it, regreased and reseated it and haven't had an issue since
Do you have a link Nicky to the bit you replaced?I ordered a replacement pipe and fitted it last night haven’t tested it.
The replacement was aluminium and the original part was plastic likely a design flaw I’d say
Do you have a link Nicky to the bit you replaced?
cheers Nicky, although my gun is ok, I should have ordered one of those when I ordered a new lance as it'll likely go at some point.Internal Pipe Aluminium | AVA Store

I'm by no means a font of all knowledge on hoses, but I've had to make up plenty of hydraulic hoses before.I don't know the pressure rating and there's no printing on the hose, but I guessed buying it from Cleantec for a simple domestic machine it would be up to the job.
When I look at the damage, it's like the wires inside break and then the outer rubber splits with the water pressure. Like you, I would have thought even if grit was to damage the outer layer of rubber it still shouldn't leak.
