Hey guys I’ve just dug out the mobi washer v15 after not using it for a while (almost 12 months)
it’s still working perfectly other than the fact when I turn it on the gun continuously sprays water, I cannot get it to stop unless I power it off, all seals are present (I know the connectors are crap) and I’ve a old gun that is doing the exact same too (it leaked badly hence replacement but kept it just incase)
so is it likely something else to do with the internals or the gun itself?
don’t want waste money on a new hose and gun if it’s something going inside that can’t be fixed
it’s annoying as it works perfectly but having the gun on constant is annoying as hell I as I have to keep stop/starting the power instead
Mine does this but it's a rusted part in the gun I think. The brass plunger doesn't return into the housing basically.
It's definitely an issue with the gun in my case not the machine. The machine it's self will happily run and pressurise without the hose & gun attached.
Thanks for the reply, yeah I’m thinking it’s more so the gun I can’t really see how internally it would do this
if I don’t connect the gun at all should the hose stop any water coming through when it’s powered on? Or with no gun attached will it still just flow through the hose?
Just a means of testing it without the gun before wasting money - sadly I can’t test it till next week now so
I'm on my 2nd gun and its playing up like yours. Time too find a replacement 🙄
Rs components do spares under the sealey brand
If no gun connected the hose is open so the machine will keep pumping. The gun cutting flow allows pressure to build and trip the pressure switch inzide
My first gun did the same. Mines get a scoosh of wd40 for any long term storage. Can't say if it helps but first gun lasted months. Second is years old now
I can’t seem to find a replacement gun on the rs components site sadly, done all the usual search methods but nothings coming up
Sorry just checked email
Not rs it's CPC Darnell always get those two mixed up

Sealey pw1712 is the same as mobiwasher
Ah great thank you very muchly for that I’ll get one ordered hopefully that will fix the issue hopefully it’s not the hose as that’s like 40 quid replacement
I ended up buying a generic gun from Amazon.
it was quite a few years ago as the original accessories (hose, gun and charger) were a bit crap, but my actual Mobi (V17? With the battery) is still working. It was one of the first generation ones they did with the built-in battery so over 15 years old. I think I managed to get some Hozelock compatible connectors and hose at some point.
@oscillatewildy I have a gun if ye need one
my Mobi died
mines is one of the original ones too, it’s at least 10-15 years old too not used that much really it still works fine bar the gun sadly so as much as I’d like a new one it seems pointless when this works ok, just need a new gun and think it will be all good again till that breaks again
I've lost my mains charger for mine ( still got the car adaptor), any idea what I need/where I can get one from?
Ta.
Holy thread resurrection etc - but Googling a fix for my Mobi which has a connection fault (hose keeps popping off at the unit just enough to cut the water flow) and found this thread with a hanging question.
From what I can gather, these are nigh on identical to the Mobi ones in case anyone needs spare bits:

Anyone advise which gun is now compatible with the mobi washers? I’ve still not got around to finding a replacement gun or if anyone has a working spare they no longer need?
Sealey sell the bits. Their pw1721 washer is a clone of the mobi v17 and I’ve had parts off them recently (a pump which I had to mangle a bit to fit the v15 mobi, needed the pump diaphragm head rotating by 30° but otherwise it was exactly the same).
they have parts diagrams and seem to keep good stock. I mailed them on technical@sealey.co.uk and their sales line is 01284 757500
Thanks hot_fiat appreciate the info I’ll drop them a email to see if I can order one from them direct hopefully they’ll have spares in stock 👍
ps i can’t even see mine or your reply to this thread on my phone, just clicked more reply’s near the top is the only reason I know you’ve replied - no idea why either of our replies aren’t actually showing on the thread
