22 Year old Numatic George carpet cleaner - Fixed for £7! (pump issues)

- An old gentleman bought this round the other week, a lovely George in need of a repair to the pump! It needed a new Diode in the end, so if your symptoms match this example then hopefully it's an easy fix! Plus, minty old George for the Numatic fans 👍
Fancy donating to the channel? I’m always in need of parts for projects, so have a look at my Amazon wishlist, and let me know who you are in the note so I can read it out on camera! - www.amazon.co....

You can't beat a george the best carpet cleaner I've ever had..
I have never seen a george so clean! honestly my eyes got indigestion, i couldn't comprehend it, lol.
I know, tbh that was the main reason I did a video on it! Was horrified when the guy said if it would be an expensive fix he'd bin it so I didn't charge much and looked him in the eye when he collected it and said treat it with care, they don't make them like this any more! Imagine finding it at the car boot for £20 with its box 👌
Sometimes when the pump still works, but no water is sprayed. This is almost certainly the brass end nozzle is crusted up and blocked.
That’s one beautiful George
Was mint! That's most of the reason I did the video tbh 😂
@@beko1987 well it was worth it lol
Lovely looking George love these early 2000's and late 90s George's with that style handle
If anyone asks me to imagine a George it's this era and style for sure!
@@beko1987 yep btw this is actually from January 2000 as it is from the 3rd week
Your diagnosis was amazing! This was such a pristine machine, looked like it had just been unboxed.
Was more process of elimination in the end! Now I know you've got to hear for the one lonely pump movement to diagnose it'd be quicker next time!
@@beko1987 every day's a school day! It's fascinating how simple they were back then, yet so effective.
them pumps work in very cool ways, using the diode to create a half sine wave pulsing the electromagnet on with DC at half the duty cycle of the AC.
Nice work Sam! Saved him from a date worse than death!
Awesome job Sam 👍👍👍
Had a similar issue on my Karcher Puzzi (Same / similar Gotec pump) but it also fried the coil. The single diode doesn't do a full rectification of the AC so you get half wave (pulsed) DC going to the pump. A pulse of DC pulls the piston back to force the water out and draw another charge in behind it then when the pulse stops, the spring resets the piston to go again. This also runs the coil at 50% duty cycle so when the diode dies you sometimes end up with full AC going to the pump which runs the coil at 100% duty cycle and eventually burns it out. That's what happened to mine. Seems George's diode failed in a manner that didn't give the pump any power after an initial spike, saving the pump. To my untrained eye, the single diode seems like a designed failure point and it's a lot of voltage as current to be handle by a single, small, non-heatsinked diode. I reckon two in parallel would drastically increase the life of the diodes.
Also the pitting on the piston could explain why it wouldn't self prime - it wouldn't have had a good enough seal on the cylinder bore to pump a vacuum to draw the water.
Oh you are clever! It's not something I've come across much before as I try and stay away from wet vacs because their finicky! But as you say, you get the 1 and only slam of the piston on its half wave before nothing and that's a good troubleshooting tip now. And since they all use roughly the same motor they'll all have the diode somewhere. Put them in parralel to increase lifespan too? The manufacturers don't want that 😂
Actually from week 3 (January) 2000. The number after the year is the week.
I have an old George but font that the 3 screws that hold the motor hosing on are seized... do you know how to fix this?
hi there i bought my george a few years ago its an 04 model the blue bucket one. its never let me down until last week i got it out of the container and it made hell of a sound but worked then when i shut it off to refill and pressed the button it didn't work ( the pump works fine). i do have another george i bought for the hose which doesn't come on at all thats an 08 gve 2 model. (the owner said its the cable). should i just swap them out or is there a way i can trouble shoot the motor. thanks!
Hi I bought one about 5 years ago and took it apart to clean under the lid. Now I’ve put it back together there’s not much suction? The suction gets better when I loosen the screws around the lid! Please help!!
I've got one but it's only 1000w yet it doesn't look like the really old ones new ones have 1250w I think.
New ones are 1000w
i got a brand new one from argos used it for the firsrt time and it cutted out and was very hot to touch, i've noticee there is a peice of foam on the air intake is that blocking the hoover?
My one as well don't pump the water
Do you know or have any ideas how to unblock the jets ?
A small needle/bit of wire might do it? Just got to rod it through but without damaging the soft metal of the jet as it'll ruin your spray pattern.
Question does the green thread section for the hose on the front come off and replaceable?
No it's moulded to the tub it was 2002 that they became removable
I got one from the factory with that issue I believe, so I sent it back. What’s that part number? My current one just died an I think this may be the issue. When you flipped it on, was the pump barely audible? That’s what mine is doing now.
I could hear it fire the Piston once if you listened carefully as you hit the switch, then nothing. Was this listing but it's ended now 😢 Must just be an diode of a certain spec though... Dunno what that spec is though... www.ebay.co.uk/itm/283960578682?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=sI5Lr_IHQTC&sssrc=2349624&ssuid=QOvj0cTJQtq&var=&widget_ver=artemis&media=Copy Good luck sir 🤞
Isn't that from 3rd week of 2000?
Yup
which diode is that?
I'm afraid I don't know 😭 Was an ebay listing, might be still there?
